I got a small amount done this week end on the skiff - between other bits and pieces that needed doing around home
as the marine ply come in 2400 long sheets and I need 4300 long by 600 for each side bottom -- so I scarfed the bottom planks and got them glued up
the scarf is a 8 to 1 taper so 6 mm ply has the taper of about 50 mm and by doing them together as pairs the angle is pretty much the same - I just marked them out and clamped them in pairs one 50 back from the front edge and sanded of the angle -- it worked a treat
the scarfs where then lined up and the planks set up with a straight edge and a coupe of screws into a board to hold them square - a piece of plastic layed down under the join so the ply sticks only to the ply - epoxy and then thickened epoxy was applied to the join and a few more screws put in to hold the join tight
so atm both bottom sections are glued with thickened epoxy and should be ready to do a bit of a trim on the length and cut the rear to the finished shape and its ready to drill to except the zippy tie stitches
and while it just looks like 2 long pieces of ply it wont be long before it looks like a boat
