Coaming




The little bandsaw is small, but cuts wonderfully (Sears 10"). With it, I was able to make short work of the compound curves of the backing plates for the coaming. At the fore and aft of the cockpit, the curves include the pieces of wood themselves, so I laminated up three thicknesses of 6mm plywood then cut the required shapes into them. Hard to see much from the pictures. Installing the coaming at the fore and aft were very complicated and it was hard to hold the plywood in place. I tried several mathematical and scribing ways to draw the curves in the boards, but finally gave up and made a little 'picket fence' of pieces of plywood and pieces of 1x2 scrap. That served as a template and gave me the curve to draw. After that, and four or six hands to hold it in place while I drove some temporary screws, it was epoxied in place and is there for keeps! Side pieces went in very easily and the line at the top was marked at a few places for height and planed back to a nice even curve. That part is not yet finished as the epoxy is not yet set up. Left to do? Trim here and there, a lot of scraping and sanding, mounting a few pieces of hardware then painting and rigging.
