Basically, I put the fin boxes in, let it sit, then went back to check later and accidently had my big, long level fall on the blank. It fractured it, as seen below, plus dented the deck but it’s actually not that bad. That I can fix. The fracture is what concerns me. It seems to have run right along the fin box. I don’t think it’s fully split near the box, only at the very end of the tail
In the photo I’m flexing the foam to show the crack. This is a stringerless 2lb eps blank. The lam is scheduled to be 6e+4s and vector net top, and 6oz e cloth bottom with a unidirectional carbon strip nose to tail. This area should be covered by the carbon on the bottom. What are my options to save this board? Glue it together with resin slurry? Extra glass patch on the tail? Is this even going to be a big deal once it’s glassed? The board thins out quite a bit towards the tail in an hpsb for a 120lb person fashion, if you you know what I mean. This is supposed to be a shortboard for good waves, so I don’t want it to snap in half on me. Thanks for any advice.
Better make sure that fin box is well glued and ridgid in the foam. If not, the fin vibration will make it a dog from the start. Espescially if it is a single. If you have the time, a great fix would be to “plug” in some divinycell and re-rout the box and as Huck suggested add a tailblock. And perhaps a tail patch in glassing. Good luck.
You will be just fine with a little glue in the seam. The glass carries the load, not the foam. If the board is completely shaped you can use a resin based glue, microballons and resin, if you are going to shape a bit more on that area use watered down white glue. Go and sin no more.
Yeah I kinda figured that it’s the glass doing the work… Separation of the skins, load bearing and all that stuff. That was in my mind but I was still worried and panicked a bit. This has been a long project so to ruin it at the last second (of shaping anyway) would have sucked. Glassed the thing the other night and it seems fine.
Progress wil resume in my build thread that’s somewhere around the forums.
