Pissing and Painting

Some say: “If you can piss, you can paint.” Of course, this is true in one sense: anyone can slap on a coat of paint. On the other hand – as with any activity – skill is required to achieve speed and the best results. And so we are finding!

Our progress on Westerman has been slower than expected. Our plan to complete the re-painting and varnishing in two weeks by Friday was always very optimistic. The decision to apply extra coats of undercoat, and the high humidity (over 80% some days) preventing us doing two coats a day, blew our plan out of the water.

We have caulked and payed some of the garboard seam (where the hull meets the keel), so the topsides are fully ready to paint, and have now had plenty of practice in applying paint … on with a roller and, always maintaining a “wet edge,” “tipping off” with a brush. This gives the best finish. Varnishing requires a cross-hatching method of application and again, maintaining that “wet edge,” so the all-important “tipping off” leaves no dragging brush marks.

Caulking in place.
The caulking seam “payed” with red lead putty …
… and the finer cracks above filled with “knifing cement.”

We have also been preparing the spars – rubbing down, and applying new coats of varnish.

Spars being re-varnished. The initial coat is thinned 50:50 with thinners, and subsequent coats have less thinners – say 80:20. A dash of thinners is always added, even to the final coats, to avoid dragging. Rubbing down between coats is needed, and six to eight coats are required as a minimum – ten to twelve is best, especially on spars.

We needed to re-mark the boot-top. Most boats have a painted boot-top (stripe) around the waterline of antifouling in a different colour. Not just a simple bit of decoration, it can help to prevent fouling around the waterline by allowing antifouling to be painted higher up the topsides. The old boot top was too irregular to be simply reproduced, so we had to start afresh. There are at least two methods. The traditional method is to set up wooden battens at the bow, stern and mid-ships, level with the line to be drawn, and then, using string held taught across the battens, mark points on the hull. The modern approach is to use a laser level. We used the former. It is a tricky task, especially on a clinker hull. Once marks had been made, we “joined the dots” with masking tape – again, more difficult with it being a clinker hull. A lot of sighting down the line to make sure it was “fair,” and minor adjustments were required, before we were happy with the result.

The top of the boot-top marked out.
Top of boot-top masked off, and a split-coat applied.

It’s Friday, and a late finish, but we have managed to mask out the top line of the boot-top, and to apply a split coat of undercoat/gloss. We are looking forward to seeing her with the gloss coats applied, but we may have to do another split coat before we can get the gloss on – that’s after rubbing down between coats with fine sandpaper, and a wipe over with a brush cleaner-soaked rag.

There is at least another week’s work to do. The lower line of the boot-top needs to be masked off; the area below needs to be primed; the rest of the caulking seam needs to be caulked and payed; and then antifouling can be applied. Only then can the boot-top be painted. Oh, and there’s still more varnishing to do, both on the boat and on her spars!

It’s great to completely finish a project (and we will be “dropping back” on Westerman to finish the job), but the most important thing is that we have learned a lot. Two weeks was never going to be long enough.

Next week, we are supposed to be moving on to our four-week Spars Module, starting with making an oar. I don’t know, but we may spend a few days on Westerman beforehand – it really would be great to get that gloss on!

A week away, a week of prep, and a great weekend.

We had a lovely time in North Yorkshire. The heather was ‘out’ and the moors looked spectacular. There are some beautiful villages, and really good pubs. The walk across the top of Sutton Bank (James Herriot’s favourite walk) gave spectacular views across the vales below. Afternoon Tea at Betty’s in Harrogate was a great experience – well done Anna, the 7th Duchess of Bedford for initiating this great British tradition!

York Minster was very grand, but I preferred the Abbey Church at Ampleforth – perhaps because an excellent tour from ‘Father Paul’ was rounded off by him giving Sylvia and I a private tour of the crypt. Crypts, cellars and basements always hold a strange fascination for me. Freud would have a reason, no doubt, but I think it’s the element of secrecy and discovery that gives them that allure.

We visited the home (and factory) of ‘The Mouseman’, Robert Thompson, whose trademarked furniture we also saw in the Minster and Abbey, and the local church. Spotting the mouse is rather fun . The adzed scalloping to the tops to his tables, pews and other furniture reminded me of our Tudor boatbuilding module – where, ironically, the adze was used to create a flat surface!

The pubs don’t just have good food and beer – they have some great books too!
A chair in Ampleforth Abbey. Spot the mouse!
I rather fancy making one of these.

Hutton-le-Hole, a beautiful village just south of the North York Moors, is home to the Ryedale Folk Museum. Nothing to do with folk music, it is a collection of reconstructed buildings from the Bronze Age to late 9th Century, and home to the Harrison Collection (of more than 10,000 curios and artefacts collected by two brothers).

Picturesque Hutton-Le-Hole

The Harrison collection includes many medical artefacts:

Stomach pump AND enema? Urgh!
Of course, faecal transplants are becoming mainstream practice now, so perhaps we shouldn’t be squeamish about eating poo!
To reduce bleeding, pain and shock, speed was of the essence when performing amputations in the pre-anaesthetic era. Robert Liston, a famous Scottish surgeon, was known as “the fastest knife in the West End.” He could amputate a leg in two and a half minutes, and his record was 28 seconds. However, with speed, came collateral damage: once he removed a man’s testicles as well as the leg; and on another occasion, he took his assistant’s fingers as well as the leg and, as he swung the knife back up, it clipped a spectator’s coattails, and he collapsed, dead, with the shock. Both the assistant’s and the patient’s wounds got infected, and they also died – a 300% mortality rate … worse than his usual 1 in 10.
Neurosurgeons still drill burr holes.
What are those odd blue bottles, I wondered. The label reads: “Glass moulds for stretching pig intestines to make condoms. C. 1840”

This last exhibit reminds me of a story from WW2. Churchill was asked if a supply of condoms could be sent to the Russian allies fighting in severe wintry conditions. They wanted the condoms to cover the ends of their rifle barrels, to stop them getting stoppered with frozen snow. “Yes, of course,” said Churchill, “Just label the boxes English, Extra Small.”

Back at Boathouse 4 this week, we have started our two week ‘Painting and Varnishing’ module. Our task is to paint the hull and varnish the brightwork on Westerman, a Navy whaler. I had de-rigged her before our holiday, and we had removed her caulking and done a few minor repairs. Now, we have to get her looking good and – hopefully – ready for the water.

The brightwork has been rubbed down, and had two coats of varnish, and the topsides are rubbed down, patch-primed and defects have been filled. Time to …
… get the first coat of undercoat on her topsides. It was a late finish to a week of hard work, but we were pleased to have got so much done if just five days.

Ah, the weekend … time to relax. A classic boat festival nearby, at Birdham Pond Marina this weekend was too good to miss. Sylvia and I went yesterday, and there were some super classic yachts and small boats, as well as some classic cars and vintage bikes. AND there was no charge for the beer and wine, because they had not requested the temporary licence in time. Very good Pale Ale, and all the better for being free!

One of my fellow students, James was there, and we met our recently-retired Instructor too. Now I believe it when people say I look so much better since I retired – after just two weeks, Bob was looking years younger already! James and I did some networking with local jobbing boatbuilders, and with Tim who runs the boatyard here. Altogether a super afternoon.

Birdham Pool Marina.

And today, Sunday, we had our daughter, son-in-law, and grandchildren for lunch and the afternoon.

Our Grandson has a new pedal bike, a step up from his balance bike. He soon got the hang of it and enjoyed pedalling up and down our road.

A place for the soul to find peace.

We have reached the half way point of my course in Boathouse 4. The year is going so fast. I wonder if there is time enough left to complete the process of putting my final years of Practice life behind me. I realise now that this is part of the reason for doing the course, even if it was not the original intent. Legal and financial strings, though flimsy, still bind me to the Willow Group – something highlighted only this week!

We have travelled today to ‘God’s own country’ – Yorkshire – and are staying in a stone cottage, just north of York, for a welcome week’s break.

It is just after 5, and I am sitting in the pocket hankerchief of a garden, that adjoins the cottage, taking in our suuroundings. A soft breeze barely tempers the heat of the sun, and the air is filled with birdsong and the buzz of bees. House Martins and the occasional swallow swoop overhead, and several different butterflies dance around me. A cock pheasant runs across the nearby field, as a pigeon swoops up, clapping its wings before gliding on.

As the shadows lengthen, the birds in the holly hedge sing even louder and sweeter, and I wish that I could identify them from the trills and tweets they are making.

The sound of the bees buzzing around the lavender, reminds me of Yeats’ poem The Lake Isle of Innisfree (https://www.poetryfoundation.org/poems/43281/the-lake-isle-of-innisfree): ‘I will arise and go now, and go to Innisfree, And a small cabin build there, of clay and wattles made; Nine bean-rows will I have there, a hive for the honey-bee, And live alone in the bee-loud glade. And I shall have some peace there, for peace comes dropping slow, …

In medieval times, rest was a healthy ‘activity’, whereas frantic work or listless idleness were taken as a sign of not being at peace with oneself. I can certainly identify with the former!

Brook cottage is certainly a lovely peaceful place to spend a week away, together. As the Welsh would say ‘Ile i’r enaid ddod o hyd i heddwch:’ a place for the soul to find peace.

Secondhand Tools, a Visit to Leeside Tools … and a Chance Meeting.

Ahhh … tools! Can you ever have too many? I have been very fortunate to have inherited tools from my Dad, and to have been given tools by one of my patients, who was the Foreman in the joinery team at a local large boatbuilding firm, Camper and Nicholson. With birthday, Christmas and retirement presents, I should have been fully equipped, but it’s strange how strong the draw is to extend ones armamentarium!

I have mainly sourced additional tools from eBay, and the vintage tool stall at Winchester Market (on the first Sunday of the month). I bought a couple of items in an on-line auction a few months ago – it would be great to attend one of the David Stanley auctions some time. I have also bought from Tooltique – an on-line vintage tool dealer, who refurbishes and sharpens their tools really well, and prices them very fairly. On eBay, it’s fun to find and bid for good examples of vintage planes etc, especially now that I know the market fairly well, but it’s getting harder to justify buying additional planes now!

One of our group picks up treasures from car boot sales for next to nothing, but a recent visit to our local car boot sale was very disappointing.

Fellow students have recommended Leeside Tools as a place to get good second hand tools, but with my Saturday mornings usually taken up with DOLS (Deprivation of Liberty Safeguards) medical assessments, I have not got around to paying them a visit – until yesterday, that is. I was prompted after one of our gang of four bought a superb Stanley No. 7 plane there for a remarkably good price.

The shop is made up of four or five extensions and rooms, so it is only as one ventures deeper into these areas that the enormity of their stock becomes clear. Wow, what an Aladdin’s cave!

As well as a wide range of new and vintage tools, the owner, David, has created a small museum, full to bursting with his collection of planes, plumb bobs, brace and bits, and more.

Museum Exhibits

Anyway, I didn’t find it difficult to find a few items I ‘needed,’ including some ‘pig-sticker’ mortise chisels, an I Sorby No.6 gouge, a Stanley No.80 cabinet scraper, and a 2″ chisel.

While there, a chap came in. “I need some tools from this list,” he said, brandishing a piece of paper I immediately recognised as the tool list for IBTC Portsmouth. And so it was, that I was able to give some – hopefully helpful – advice to one of the students due to start the joinery course in two weeks time. “Take a look at Tooltique.co.uk for your saws,” I told him, hoping David wouldn’t mind – well I had advised on his purchase of a Stanley No.4, boxed, for just £28, a reasonable starter block plane, a £6 vintage coping saw, and some chisels, including a nice I Sorby 1/2″. In fact, I rather enjoyed helping him spend HIS money!

NHS Spending and Political Spin

A LITTLE ASIDE FROM BOATBUILDING:

I am no longer a regular GP, but I have witnessed and experienced the strain on NHS services and workers from the perspective of General Practice, which has been particularly hit by the reduced funding under the recent period of austerity. So, perhaps more than most, I maintain a close interest in the NHS, and was interested to hear the recent announcement from our new Prime Minister, of an extra £1.8 billion for the NHS. This announcement bears close scrutiny.

The headline figures are an extra £1.8 billion over the next five years, including £1billion for the coming year.

The 2018/19 NHS England budget was £115 billion, so an extra £1 billion for this year is only an additional 0.86%.

THE BACKGROUND:

Accounting for inflation, NHS spending has historically grown at an average annual rate of about 3.7% from 1950/51. However, the average growth between 2009/10 and 2014/15 under the Coalition government was 1.1% and from then to 2016/17 under the Conservative government was 2.3%.

Last year the government announced that an additional £20.5 billion in real terms will be made available for the NHS in England by 2023/24. When it was announced, this meant an average increase on the NHS’s budget of around 3.4% a year (i.e. nearly back to average annual increases). However, with inflation over the next few years set to be higher than expected, the actual real terms increase will be less than 3.4%.

At the time, health experts said that this money will “help stem further decline in the health service, but it’s simply not enough to address the fundamental challenges facing the NHS, or fund essential improvements to services that are flagging.” In January 2019 the National Audit Office said: “There is a risk that the NHS will be unable to use the extra funding optimally because of staff shortages.”

Across the country, many NHS trusts are in deficit, because they are spending more than they’re bringing in.

The NHS was also asked several years ago to find £22 billion in savings by 2020, in order to keep up with rising demand and an ageing population. So, the Government is promising nearly the same amount of increased spending over five years as the amount of savings asked of the NHS for the same period!

IS THIS £1.8 BILLION NEW MONEY?

The Nuffield Trust has said that this money isn’t new. It says the £1 billion added to the NHS capital budget was actually “cash hospitals and other NHS trusts already have, but have been forbidden to spend. They earned it last [year] in incentive payments for cutting their costs”.

But this money couldn’t be spent on the day-to-day running of hospitals, so it had to be spent on capital projects instead: things like IT, equipment or new hospitals. Ironically, with a total spending limit placed on capital spending, trusts found they weren’t going to be allowed spend all the incentive scheme money once they had it.

The Health Foundation says that “As a result of these spending limits NHS trusts were asked to reduce their capital spending plans by 20% … This meant that some trusts had money available to them which they were being asked not to spend.” This 20% reduction has now been reversed with the announcement of money for the NHS.

As the Health Foundation puts it, from the perspective of NHS trusts, this is “money they’d already thought they could spend”. But the Health Foundation also says that from the Treasury’s perspective it’s correct that this is ‘new money’—as it’s an extra £1 billion of spending this year that it hadn’t planned for previously.

The Nuffield Trust had the same view. It says that it “will feel like a new spending commitment for the Treasury. That is because it will no longer be able to recycle NHS trust cash stored in government coffers to fund other bits of government funding, and the total amount of money going out will therefore increase. However Mr Hancock was wrong to claim this was ‘new money’ to the NHS. From the point of view of trusts it is not.”

TO CONCLUDE:

NHS spending in the past decade has increased annually much less (about 60-70% less) than the average annual increase since its foundation.

The latest announcement is for a 0.8% annual increase for this year – hardly likely to reduce the approx 40% of trusts in deficit!

The Treasury will be spending more than it expected on the NHS, but NHS Trusts will be accessing money that they had already earned (but told not to spend).

We have learnt not to expect our representatives in Government to be straight with the voters, and tell us how it really is. The NHS remains a political football, when what is needed is a cross-party consensus, long-term planning and public agreement over what should and should not be funded.

Silly anachronisms continue. For example, a well-off patient with an under-active thyroid, has ALL their NHS prescriptions free, not just their thyroid replacement tablets. Conversely, someone who is struggling to make ends meet, but not in receipt of key benefits, may be paying for three or more items for their chronic eczema/ asthma/hypertension …

The NHS is a ‘holy cow.’ Politicians can play smoke and mirrors with funding pledges and announcements, but short-termism, and fear of upsetting patient groups, means that nothing really changes.

On Planks and Planes

Mermaid is an Itchen Ferry. These small gaff-rigged cutters were originally used for fishing in the Solent, and often raced in town regattas. Mermaid’s final resting place is Boathouse 4, where she is used for planking practice by the IBTC students. Each student puts on a plank, and the practice planks are then removed, to be duly replaced by successive cohorts of students.

The preparing and fitting of my practice shutter plank went remarkably smoothly. Just a tiny gap towards the bow, which would ‘take up’ if she were ever to go back in the water.

With wood, the force of expansion with increasing moisture content exceeds that required to compress the wood. So, when ‘taking up’ occurs, the expanding planks compress the caulking seam (and the caulking material) sufficiently to dent the adjoining edges of the plank and make a better seal. That’s why traditional wooden boats open up when dried out, and are really best left in the water, with only brief periods out for repairs and antifouling.

Mine is the upper of the unpainted planks – quite a nice fit.

Practice plank fitted, it’s time to do my City and Guilds ‘test plank.’ Normally, C&G planks are not shutter planks, because they’re more difficult. Happy to do another shutter plank? I was asked. “Yes, of course,” I said, my fingers firmly crossed.

So, it’s back to Lilian:

Nearly fully planked, here’s Lilian, with my spiling batten stapled in place.

I cut the plank to size, put the bevels on the edges and …

… she was nearly there when I tried my ‘first fit.’

After much to and fro-ing between boat and bench, to take off just a few shavings at a time, I got her ‘home.’ The gaps disappeared as I got the plank seated right in – what a relief … I was really pleased!

When these shores were removed, the plank stayed in place … result!
Arguably, the fit is too good, as the wood will swell when she is launched, and there are no visible gaps now. However, a tight shutter plank can be useful in pushing the others closer together.

I am now making a scarf joint for the joint with the plank that is to continue forward to the stem (bow). I will then add a small bevel for caulking before priming the plank and fixing it in place with screws and roved copper nails.

And planes?

Well, the inner aspect of the plank has to be bollowed or ‘backed out.’ This is get the plank to fit to the inner curve of the hull and to lie nicely against the timbers (ribs). Templates are made for each timber and the plank is shaped to fit using a bollow plane.

I had an old wooden plane with a rocker, but no transverse curvature, so I fettled this by adding a transverse curve to the sole, and grinding the blade to shape. This worked well, getting the plank to fit at each station, but I needed a different plane to even out the inner curve long the length of the plank.

In my worksop (Doc’s Den), I found a wooden plane with a flat sole. Ideal, I thought – I just need to put a transverse curve on the sole and it will work a treat.

I shaped the sole, and then the iron; rubbed in boiled Linseed oil; and re-glued the handles. The next day, at the Boathouse, I noticed the maker’s stamp on the plane:

mark1.jpg
Dad’s plane, now fettled …
… to give it a curved sole.

Curious, I went to Google, and found that this plane was made in New South Wales, Australia, by Berg Tools. They made wooden Planes in the 1940s and 1950s. And there was picture of a plane, just like ‘my’ plane!

bergs-continental-smoother.jpg
The cut-out section at the front looks like an amendment, but is actually the original design (similar to those made in the Baltic area). Perhaps it’s a little crude – I can hear my Mother’s comments now about the archetypal Australian male … always discriminating my Dad from the stereotype she described.

Anyway, it worked a treat: the ‘swish, swish’ sound, as it smoothed and bollowed out the inner surface of my plank, was wonderful.

I have altered a plane that I now know to be my Dad’s, but I have made it useful and fit for the task at hand. I’d like to think that he wouldn’t mind my adjustments, and would be happy that I had found a good use for it, pleased that I had found pleasure in its efficient and effective shaping of my test plank.

On planks … and axes & adzes … and Valerie

Well, I am pleased to report that my plank repair went OK and, after a second steaming session, we had the repair in place – albeit with a lot of clamps! I pulled the wood out of the steam box and ran to get it fixed in place – just a few minutes to work the wood before the heat started to dissipate too much to allow further movement.

All hands to the pump to get the plank clamped in place.
The remarkable twist and curve that we achieved by steaming.
Clamps exchanged for coach bolts for the second fixing.
Glued, bedded in, and screw fixings in place. What a relief!

Now, to caulking. Caulking is the technique of driving oakum (rope fibres and tar) or – as here – cotton into the plank seams, to make them watertight. Locally, there were teams of men who would be called in to caulk ships. Many of these teams came from the Isle of Wight – hence the term “Caulk Heads” for the island’s residents.

After making a caulking seam between the the new and adjacent planks, I caulked the seams.

The caulking cotton is pleated in, and then driven home. A set of caulking irons numbers about a dozen, and the caulking mallet has iron hoops to lend it heft. Thankfully, I don’t need a set, as a single iron fetches £10-15 and a mallet about £90.

A Tudor interlude.

The 26th and 27th of July, saw me doing some Tudor shipwright work. The 16thC Mary Rose museum is nearby, and the College has long run a module on old shipwright techniques. We have had a trip to the woods on the Stansted estate to look at how shipwrights would select trees for timber, and this phase was to make some parts for a ‘Jollywat’ – a tender/deck boat – for the Mary Rose. The Jollywat became the more familiar Jolly boat.

So, I did some axing and adzing and marking out of timbers for the proposed Jollywat.

It is remarkable how fine a shaving can be obtained, and how fine a finish achieved, with such ‘crude’ tools – if not in my hands, then at least in those more experienced!

Back to my plank repair:

After caulking, the seams were filled with red lead putty.

Red lead powder (rather toxic) is mixed into ordinary putty – the same sort of putty that is used in wooden window frames. The red lead stops marine micro-organisms from trying to eat the caulking material.

I have filled the holes left from removing the brass tacks that held the tingle in place, using thin sticks of oak – a process called ‘sprigging.’ The repair is now completed, and I am pleased and relieved in equal measure – glad too to be moving on to …

… my ‘practice plank.’ Yes, after doing a very difficult plank repair, I am putting a plank on an old boat called Mermaid as part of the college’s set curriculum. We do a ‘Practice plank’ and then a City & Guilds test plank.

Planks/strakes are generally put onto the boat from the bottom up and from the top down. That results in a gap in the middle of the hull, which is filled by the final plank, called a ‘shutter plank’. Fitting shutter planks is doubly difficult compared with the other planks

So, naturally, I have opted to do a ‘shutter plank.’ Well, I didn’t think I should do a simple plank after my recent repair on Tom Sherrin!

And finally, … to Valerie.

Today, my friend Craig and I went for a bit of a sail. We had both been given a trip on an 1895 gaff yawl called Valerie as a Christmas Present. What a beautiful boat she is, and it was absolutely super to sail on her in the Solent.

Heading out of the river Hamble
Happy at the helm.
Superb joinery – a scarf joint. The piece of teak used to make this top-class teak deck alone cost £20,000.
Topsail set.
Who’s that cheerful chap at the helm?

After discussing the IBTC course, I said to the skipper that if he was extending his fleet, I’d be available for work in 7-8 months’ time. Alas, he’s planning to downsize his operation. “Would you sell Valerie?” I asked. “Any boat is available for sale” he replied. So, I asked him what’s she’s worth, but he just said that she’d fetch three times the price if he sold her in the Med.

Ah well, one can but dream … just hope my shutter plank isn’t a nightmare!

Tingles and plank repairs … and the skinning of cats.

Staying with Tom Sherrin, my next job was to remove a ‘tingle’ and take a look beneath it.

A tingle is a batten or board used as a patch to cover a split or damage to the planking of a boat. Patches can also be made with lead or copper plate. Properly caulked and fastened, a tingle provides a sturdy repair until the damaged plank can be properly replaced.

At the forefoot on the starboard side there was a large copper tingle.  It probably covered a broken plank. The tingle had to come off, and whatever lay beneath would need a proper repair.

Taking off the tingle – a large thin sheet of copper fixed in place over some sealant with copper tacks.
Minus her tingle, there’s trouble at the bow end of the lowest (garboard) plank.
After removing old filler, a long diagonal split in the garboard is revealed. It has been repaired with bronze screws which had severely corroded due to electrolysis (de-zincification).
I cut back the forward section of garboard plank.  This revealed an unusual construction detail (never before seen by any of the instructors at IBTC): there is no rabbet (step) for the garboard to rest into. Instead, it is laid against a bevel on the keel, which means the plank is not securely seated onto the keel.  


A groove has been formed at the bottom edge of this bevel, seemingly by the attempts to caulk this seam as part of the repair to this damaged area. 

So this repair was unsuccessful, either initially, or it failed some time later. That’s why a tingle was added to fix the leak, until a substantive repair could be done.

A plank repair is called for. Step forward Stuart Morgan!!!

I cut back the damaged section, and scarfed the end of the plank.

A scarf joint is a way of joining two pieces of wood with a diagonal cross-over section.

Time for the dark art of spiling.

Spiling is a way of marking out the shape of part of a boat, where it is curved or otherwise complex, and cannot be fitted directly. A spiling batten is laid over the gap to be filled, such as a plank or bulkhead. The accurate lines of the edges for the piece being made are then drawn onto the spiling batten. There are at least two ways of making those lines – and, of course, I used both!

A loosely fitting piece of plywood, nailed in place, makes my spiling batten. A rectangular piece of wood (a spilling block), run along the edges of the adjacent plank and the keel, with a pencil on its inside edge, scribes a line parallel to the desired size of my plank repair’s outer surface.
The second technique is to use a set of dividers to take the measurements to the edge of the plank.
The spiling batten is removed, nailed to the wood to be used for the repair, and the outline of the plank to be made is transferred from the spiling board, by reversing the above processes.
The repair piece duly cut out. Now it gets even more complicated …
A so-called ‘bevel board’ marked with the angle of the bevel of the plank above, and the angle of the contact face on the keel.

I now need to shape my repair piece to fit in place, getting the bevels right by using the information on my bevel board. All this while being unable to offer up the board to the hole, because it is straight and needs to be both curved and twisted.

And here’s where the skinning of cats comes in.

Ask the opinion of three doctors, and you’ll probably get three different answers. So it is with boatbuilders. There are seemingly several ways to skin every cat … every task in building or repairing a boat.

We are short of Instructors due to sickness and people leaving, and due to difficulty finding replacements – a bit like General Practice! The paradox is, that, nevertheless, there are often multiple varied opinions on how we could/should complete each project. This plank repair has exemplified the issue.

The initial advice, was to carve the repair piece to the inner shape, and then carve out the outer face. It would be difficult. The alternative was to laminate a repair piece on a jig, but this would be no less complicated or difficult. On Thursday, it was suggested that the repair piece could be steamed to shape, though others disagreed that this was possible. Nevertheless, the final decision is to try and steam the repair in place, albeit this is something of an “experiment.”

All I want, is to do a good job, and to enjoy the work. Watch this space.

A graving piece, orDutchman repair.

Tom Sherrin is a Poole Harbour Pilot Launch, designed in the 1960s by John Askham of Bembridge, Isle of Wight, and built by James and Caddy of Weymouth.   She was launched in 1970, and served as a pilot cutter until 1988, and was subsequently sold to the Harbourmaster in Alderney, for use as a pilot boat, work boat and occasional push tug. In 2000 she was purchased by the MVS (Maritime Volunteer Service) in Poole. She came to Boathouse 4 in December 2015.

There is still much to be done for her restoration (lots of pics on this hyperlink), and my first task on this boat was a minor repair, requiring a ‘graving piece.’

Rather than replace an area of minor damage, it is often possible to make a repair by fitting a graving piece. This is a small piece of wood, often diamond-shaped, or an oblong with pointed ends, laid into the damaged area, once the damaged timber has been removed.

A graving piece, often nicknamed ‘gravy bit’, is also known as a Dutchman repair or just Dutchman – one famous small yard, Hilliards, uses the nickname ‘little boy’. Of course, the reference to Dutchmen and little boys, is to the apocryphal little Dutch boy who put his finger in the dyke to stop a leak.

After deciding how much timber needs to be removed, the graving piece is made, just big enough to cover the damaged area.

The graving piece is cut out of a piece of wood that is thicker than the depth of the repair, making it both stronger and easier to handle. Once fitted it is easy to remove excess thickness with a plane or a sharp chisel.

Next, the graving piece is put in place on the plank, and carefully scribed around using a knife to ensure that the scribed lines perfectly define the shape of the graving piece. The damaged area is now chopped out.

The graving piece is then glued into place, and often screws or other fixings are added once the the excess thickness has been removed to make the patch repair level with the surrounding wood.

On the keel of Tom Sherrin, just aft of the bow, a knot in the oak had split open (probably due to the drying out of the boat). The hole created extended right through the four inch thick keel.

After cleaning off the antifouling, I was surprised to see light coming through from the other side!

A two part Dutchman repair was agreed. This is known as a ‘top hat’ repair, because the outside graving piece overlaps the deeper part, like the brim of a top hat. This has the advantage of the water pressure pushing the outer part against the inner part, making a sounder repair.

Here, the deeper graving piece is being held in place, to mark out the hole to be cut.
The recess is made.
The hole through to the other side is enlarged here, ready to be filled with a plug
The hole plugged, and wedges driven into the split; all glued in, and ready to be trimmed.
The deeper part is now glued and screwed in place.
The brim of the ‘top hat’ has been fashioned, a wider recess made, and it is now being glued in place … nearly there!
The finished repair. Screw holes have been plugged, and the Dutchman repair completed by planing the surface level. Should outlast the rest of the boat!

My fellow student, Tom, did a one piece repair to the smaller defect on the other side.

As I will elaborate upon in my next post, there is more than one way to skin a cat, and that’s certainly the case here. As the Head of the College said, “In a commercial yard, you’d just fill the hole with epoxy and wood fibres, and have the job done within an hour or two.” This, after I had spent a few days doing this repair! Never mind, it’s always good to learn the gold standard techniques, and gain experience and skills in doing that … you can learn the short cuts later.

It’s like that in medicine and, no doubt, in other professions too. As medical students, we learnt how to ‘clerk’ a patient by taking a full history and performing a full examination … taking nearly an hour at first to do so. On qualifying, we were clerking in hospital admissions in a fraction of the time. A few years later, it was 10 minute consultations in General Practice!

I sometimes feel frustrated at how long it takes me, to complete a job on a boat. The others feel the same. Worth remembering then, that everything we are doing is for the first time; how one does speed up after the first time of doing something new; and that no skill comes without repetition and experience.

My next ‘gravy bit’ won’t take me half as long!

Big Boat Boatbuilding – knees and floors

Three weeks ago, we moved from lofting to Big Boat Boatbuilding, starting with making and fitting new quarter knees and refashioning some floors on Lilian.

The Lilian is a 25ft. open motor launch built in 1932 by Hincks Boat builders of Appledore in North Devon.  She was commissioned by Mr. Plumber, the owner of the Anchor Hotel at Porlock Weir, to take guests on sightseeing tours of the Exmoor coastline, pick up passengers from the paddle steamers Waverley and Balmoral and bring them ashore for cream teas etc. Later, she was used for commercial fishing until 1984, and has been in private use since then.

She is of Carvel construction, and was built with Larch on Oak with a solid Elm stern and was powered by a three cylinder diesel engine.

With a new keel, new planks, and new timbers (ribs), there is little left of the original boat, but she still has her frames and some deadwood structures.

Nearly fully-planked.

Our first job was to fit a pair of Quarter Knees. Think of the hind quarters of a horse or cow, and you can understand the nomenclature and siting of these knees (brackets).

A view of the transom. The beam for’d of the transom will form the front support of the aft deck. The quarter knees will provide a strong buttress for the gunwale and the transom. It needs to abut the aft deck beam in order to support a Samson Post which will be positioned just the other side of the deck beam, and be used for towing etc.
A sketch to show the proposed port quarter knee in place, made using 3mm thick two inch strips of oak, laminated to shape with a solid oak infil.

After making a plywood template for the required shape, wooden blocks (cleats) are bolted to a worktop, and the laminates are coated with glue, and then clamped in place for 24 hours.

With the laminates cleaned up, an infil pice is made, and glued in place.
The transom slopes foreward, the inwale slopes outwards, and the aft deck beam slopes backwards – three bevels here – making fitting the fully formed knee something of a challenge!!. At last a good fit.

To fix the knee in place, pilot holes were drilled, and thick copper nails driven through. We used three 6 inch nails from stock, but needed some longer ones as well, so I made three longer nails from 6mm copper rod. Domed copper washes are then driven down over the nail, and excess material is cut off the protruding nail, which is then ‘peined’ over the washer, creating a rivet-like fixing.

The finished job: the port Quarter Knee, held in place with copper roved nails.

If knees aren’t what you’d think them to be, then floors are still less so. You don’t stand on the floors of a boat, you stand on the deck. The floors are strong structural timbers that lie across the bottom part of the boat, to which the planks are screwed.

From front to back, the big timbers going across the bottom of the boat are : First futtock of one frame, ‘my’ floor, and the first futtock of the next frame. The thinner battens of wood are called timbers – much room for confusion and mis-naming here!

Due to the movement of the shape of the boat in its restoration from a very dilapidated state, the floors and frames are no longer fitting properly. The gaps under ‘my’ floor were up to 10mm in size. In addition, the Limber Holes, that allow big water to flow along the boat and not collect in pockets, were too wide. By scribing a line parallel to the inside of the hull, the floor was re-shaped, and Graving Pieces were fitted to reduce the size of the limber holes, so that there was sufficient wood to take a screw through the plank below.

A ‘Graving Piece’

Having got a good fit, I drilled a hole through the frame and keel, and made a bolt out of 1/2 inch silicon-bronze rod (using a die to make a thread for the first time in over 40 yrs!).

‘My’ Floor is now fitted, with no significant gaps; bedded down with butyl rubber sealant, through-bolted to the keel; and the planks screwed to the floor from below.

These were two projects that were veery challenging at times, but equally satisfying to complete. I have gained lots of useful experience in various techniques: laminating, fitting to complex bevels, making copper nails, roving copper nails, scribing wood to fit curves, making bolts, drilling 8 inch holes accurately ….

In the last few days, I have started working on another boat: Tom Sherrin – a Poole Pilot Launch. This is another long-term restoration project. I have been tasked to undertake a repair on her keel.

A large knot in the keel. The keel is 4′ thick, but I can see light coming through from the other side. This calls for another Graving Piece – and one a lot more substantial than on ‘my’ floor.
Don’t be thinking that this wood is rotten. The wood is solid, despite the large defect. In fact, the central part of the knot is as hard as bog oak. Just goes to show that salt water alone doesn’t rot wood – it’s being left in fresh water that rots wood.

A new arrival

The CMB from Duxford has arrived. I haven’t forgotten my promise to do a post on the CMB – watch this space.
