Managed to get Frame C completed quickly over the weekend. Straight forward, a little tricky setting out for gluing as there is no backing plywood frame, however careful use of the Irwin Clamps solves the problem. Essentially we lay the pieces out on a large board, clamp it down as it should be completed and then draw around the frame in pencil on the board. Lift all the pieces and lay a clear plastic sheet over the board. Then replace and clamp the frame parts. When ready to glue and screw in the “brackets” we release each clamp in turn, glue, screw down the bracket down and re-clamp. There’s usually a logical “king” piece or two to work away from, get that one piece done right and the rest fall into place. Kinda!
We’ve also made good progress on Frame S. Similar to all the other frames careful cutting and laying out. “S” is a little different as it has structural pieces on both sides of the plywood sheet. Additionally the top piece needs to be left proud by 8mm ready for bevelling when we from the roof of the cabin.
As it will be slanted a number of the structural pieces also need to be bevelled ready to receive part of the cockpit construction. This was fun(ish) as I had never done a bevel before. However we had bought an electric planer for just such an occasion. So after some practice on a piece of scrap, and checking the drawings about 20 times bevelling commenced, and to be fair they look pretty good.
Hopefully tomorrow we can complete Frame S.
We will slightly delayed completing Frame D as the bottom part of the frame, D12 needs to be in hardwood. So this is will need to be ordered along with the hardwood to for the keel floor, the mast frame top and posts and for the stringers.
However plenty to be getting on with as the materials for the jig will arrive by the end of the week. I have also got some epoxy filler compound so can go back through the other frames and do some filling of screw heads and general tidying up ready for mounting on the jog. Once it’s built.
