What sort of epoxy did you use? Any quick set will probably be too brittle, also mixing in some finely
chopped fiberglass fibers would help.
If not...the best performing solution is FCS2 boxes...I wish all my boards had fcs 2 boxes now.
Hmmmm, that thread dates a gooood while back.
Back then - if I remember correctly - I tried it with a regular 2-parts epoxy glue with carbon or glass fibers mixed in, which was waaay to brittle, nor it sticks well with plastics.
At the end my solution was to install SS threaded inserts and replace setscrews with smaller ones (with a finer thread). Worked like a charm. This board is still in use every season with absolutely nothing to report.
At some point I even though about making a batch of repair kits for sale, but at the time I wasn't able to come up with a reasonably-priced installation medium for the inserts. Besides the fact that it requires an unreal level of manual dexterity. Basically you get only one shot at getting the insert in, if you go too far even by a fraction of 1/16" - your fin box is pretty much - shot.
Ahh, actually there was a downside to this method, on one occasion I was transporting the board on the roof rack with fins removed and due to wind all setscrews felt out. Luckily they all felt into the fin boxes and I haven't lost any.
