Polycarbonate fins... How do you attach them?

General Discussion

I remember seeing an Eaton zinger or bonzer with what looked like
polycarb fins…

If you had access to scrap polycarb and wanted to experiment a little, how would you attach them to a board?

-Super glue
-silicon
-5 minute epoxy
-contact cement
-pine tar
-old bubble gum
-unflickable boogers?

glassed into the board.

by inserting the polycarb fin into a cut slot.

fyi:polycarb is a co-polymer to polyester resin.

Thanks Herb.

Thanks Ace.

First polycarb fins were cut… Small supercharger inspired type fins to slap on to my keel fin fish.

Inset them 1" deep per 10" depth of fin, anchored in woodies (3/16 solid wood).  Poly resin works fin, drill holes thru the base of the inserted part of the fin.
