With some help from a shipwright friend, I have finished lofting the 10ft Gartside dinghy, and am pausing to tackle another, rather nautical, project. <\/p>\n\n\n\n

The last couple of lines – the Diagonals – were plotted, but I just could not get the required ‘fair line’. The lines just looked too flat amidships. After checking, double checking, even triple checking the coordinates, I was stumped. So, I phoned a friend. <\/p>\n\n\n\n

With him giving me a firm nudge, I grasped the nettle and, by moving one nail on each of the diagonal lines – one by several millimetres – we soon had two pleasingly fair lines. <\/p>\n\n\n\n

Now, all of the views, with all of their intersections, must correlate with each other. So, I had to use the changes made to the Diagonals to re fair the lines on the other three views. I think I had been reluctant to boldly change those points, because of a dread of having to go through this process of ‘lofting to agreement.’ Happily, with just a couple of points to change, the process went pretty well. <\/p>\n\n\n\n

So, here are some pictures of the final result:<\/p>\n\n\n\n

The Half Breadth view, on the left hand side, shows the curve of waterlines (which include curve inwards towards the bow, where the lower planks will need to be pulled in to create a ‘tuck’). The right side shows those demanding diagonals, which are looking nicely fair!<\/figcaption><\/figure>\n\n\n\n

The stem detail on the Profile View.<\/figcaption><\/figure>\n\n\n\n

The Body plan, gives the end-on view with the front half shown on the right, and the rear half on the left.<\/figcaption><\/figure>\n\n\n\n
\"\"
The transom is raked, so I had to do a transom expansion, to get its proper size – both fore and aft faces of the transom have been drawn in.<\/figcaption><\/figure>\n\n\n\n

The final result.<\/figcaption><\/figure>\n\n\n\n

And now for something completely different.<\/p>\n\n\n\n

I have been asked by a friend to make a display case for his Navy sword. I had already made a start, a few weeks ago, preparing some yellow cedar from the ‘Winchester wood haul.’ <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The smell of the cut cedar is lovely, and the grain pattern is gorgeous – at least it is to look at – but it’s a devil to work, as the grain direction changes so much!<\/p>\n\n\n\n

\"\"
A lot of shavings were made to get to this stage!<\/figcaption><\/figure>\n\n\n\n
\"\"
The waves in the grain seem most appropriate for this project.<\/figcaption><\/figure>\n\n\n\n

Yesterday, I started on the joinery. Using a Paul Sellers technique, a simple jig ensures that the dovetails are cut square and true.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I’m aiming to use mitred dovetail joints, particularly at the back, where I need to cut a rebate for the back panel of the case. They are tricky joints, and that rebate may be a bit of a challenge with the wavy grain … fingers crossed!<\/p>\n","protected":false},"excerpt":{"rendered":"
