58948Re: replace epoxy with resorcinal??
- Oct 27, 2008Hi Bill
Sure 'nuff, all the resorcinol joins on old ply boats I've rebuilt
have crystalised, dried out, & failed over time,
Early Mirror dinghies were stitch + tape, using Polyester resin....
seen a lot of those fail, too.
I've never come across an example of a well made epoxy joint that
failed in the glue....... ALWAYS, the wood lets go first.
Regarding sheathing & coating....... Polyester/glass is a disaster
looking for a place to happen..... the wet gets in between the
sheathing & the wood, the wood STAYS wet, & rots.... VERY fast. I've
seen a ply over frame boat where the entire bottom was rotted out, &
the only thing keeping it afloat (briefly) was the 1.5 mm of
well built ply/epoxy boats with glass/epoxy coating are the most
durable & maintenence-reduced you can get (even with shoddy modern
ply.... & Doug's right about the wood being just as important)
....Sorry!! I hate using it too, but I wouldn't build a boat using
anything else unless I considered it "disposable"
