Managed to hit myself with the fin with such a force that it sunk the fcs fin box in to the foam. Going to do a home fix, does anyone have any advice? I plan to fill the hole with q-cell and put the fin box back in, then i’m assuming to sand the area down and cover with some new fibreglass?
That’s one way that a lot of people do it. Just understand that it was the supporting foam that failed here, not your plug; and you’re pouring a big blob of resin into that
My preference is to rout out an oversized cavity and glue in another piece of foam from an old board. Preferably an old dead longboard that was build with a higher density foam and is now only suitable as a donor. You cut the foam plug so if barely fits the cavity and has some excess coming out the top (meaning a 1" deep cavity gets filled with a plug that’s at least 1.25" inches so the excess stands above your glass job). Glue it in with epoxy or Gorrilla Glue or other similar adhesive. When that sets, you shape the excess off so the foam plug sits flush with your glassjob, and then glass over it. THEN install your new FCS plug as normal. Now you have a regular plug install into “new” foam that has a little extra support at the bottom of the foam insert from the glue, not an irregularly shaped blob of resin.
It’s FCS. Why go to all the trouble of pouring filler or replacing the crunched foam. Over Kill. Just drill out both plugs with a hole saw and install a Fusion box… simple fix. Stronger and easier to do.
