YOu want it cheap. wrap a piece of waxed paper around the inside tube
and pour the gap with epoxy compound. Use a couple layers of paper to
get the clearances you need. Use a piece of styrofoam to hold it in
place and for the bottom dam on the tubes. For the same process in
bigger dollars use Moglice.
I like that idea, too! I do a lot of boat stuff with West Epoxy...

What IS Moglice??
