I made them. I built a simple mold out of MDF. Its 1.5" x 4.25" and about 15" long.
Basically, I wrap the mold in thin (1-2 mil) plastic. That way I don't have to spend time waxing the thing and the part comes off alot easier. It doesn't have to be perfect anyhow. I use 1.5oz mat and 6 oz cloth to wrap the actual tube. There are about 5 wraps of the 6 oz cloth to make a wall thickness of about 1/8". I would have liked them to be a little beefier, and I still have some tabbing to do in the bilge when I get that boat back, so I'll probably wrap them a few more wraps at that time.
I have some cleaning up to do, but these are all set to go into the boat when that part of the project comes up. I am using the same system in my Mako 21.
