I had no plexiglass when I was splicing the sides and bottom of my pirogue, and it's thirty miles to the nearest place to aquire plexiglass.
So I split open some plastic compost bags, taped them on an old Humble oil sign,laid down my plywood, applied too much epoxy (Remember, this is my first boat that has a possibility of floating. I ain't taking any chances!),centered my carefully carved plywood scab, applied more epoxy, streched another compost bag over the joint, laid an aluminum"neighborhood watch" sign on the joint, and then put about 15 bricks on the sign.
It worked great! However, the printed side of the bag seemed cleaner, so I put the printed side toward the epoxy, And the epoxy glommed onto the printing.
Actually, It looked pretty cool. If I had centered the logo, or the picture, I might have left it. But of course, I had the instructions, in mirror image running diagonally across the scab.
I spliced both sides at the same time, and five minutes with a belt sander took care of the problem.
But, when I spliced the bottom together, I made sure I got the inside of the bag against the epoxy.
I have made so many mistakes on this boat. But I'm learning. And I already have another pirogue cut out, just waiting for this one to get itself off the bench!
And some canoe plans ordered.
And a passel of small sailboat plans perused!
Then a 32 foot sloop.
Then a 60 foot yawl.
Then a 180 ton schooner.
The paddle and sail driven oil tanker will have to wait till next Summer.
