Hi guys, hope you are having a good weekend. I have been working on a summer board, and it has been going really well, it’s my 6th board now and I am getting better at all the skills needed to make a decent board! This one has been going too well, and today I had a cock up! Routing out the centre plug I hit the stringer and it moved the jig and made a mess, it was my first time installing post lam! I’m left with a pretty ugly hole, how would you repair?!
Should I transplant a piece of EPS and glass over? Or fill the hole with epoxy/milled glass, if this, how do I stop the dreaded exotherm?!
you got lucky, its black. since its black it gonna be really easy to color match…IMO I will plant a small eps foam in there, sand it below surface, then fill it with q-cell mixture with little black in it so it have the same color as your board, then clear lam it.
No big deal. Take your time and do it right. Cut a piece of scrap EPS to fit as snugly as possible into the hole. Glue it in the hole. You could just use regular elmer’s glue, as you are just aiming to hold the foam in place and you’ll be routing through it anyway. Sand the EPS level to the original foam. Re-glass with black pigmented resin as you did the rest of the board. Fair the edges of the glass to make the repair flush. Re-route the fin box.
Thanks a lot for the advice guys! I’ll give it a go this evening. Would you route the hole out square, or just try and cut a piece of EPS the shape of the hole and fit it in?
Just cut a piece of EPS the shape of the hole and fit it in. EPS is a little malleable so better to make the piece a little oversized and force it in so it fills up any gaps.
even in the uk you can melt eps with a black board a friend insisted on a carbon board, i warned him the a few days later sure enough i was reparing it! Take the warning from every one and ether be ultra carful and never leave it in the sun un covered or paint a light colour.
Not so much heat as sunlight in my unscientific opinion. Someone correct me here…
The black color is absorbing solar energy (all light wavelengths) which is then converted to heat energy. Black aborbs all wavelengths. White reflects them. When the sun is directly overhead, the heat will be greatest – solar noon and/or the summer solstice.
UV light does the longterm damage to plastics, skin etc.
