Shame indeed… I have more that I’ll use for longboards and maybe another snowboard.

only picture I really have. Used a straight edge and razor blade to cut the overlapping joints at the same time so they would match up nicely. I did do this over a week prior to pressing, and I hear the temperature can warp it a lot if you wait.

Are you talking about the wave looking hump on the base?
Yea there’s a couple small humps in the red, and a tiny bit in the white. Really? Packing tape is that bad?? What would be a good alternative? Or do you just skip it all together?

What kind of mold are you using?
Show some pics of mold and vac bag system, that might help answer a few questions.
Sad to see the dollars wasted on something that won't see the snow.
Sorry to have to say this again (I've said it close to a dozen times)
Start with a simple design, base, core, glass, epoxy.
Get your process down.
Then spend the money on fancy materials and designs.

I probably should have stuck with just rocker or just camber… When I get home from work I’ll post some mold pics, it’s a (fairly ghetto) wood mold.

get a spray bottle and mist some water over the core in the tip areas, on both sides top and bottom.
Lay the core in your mold and just put a bunch of crap on top of it that's heavy, leave it like that for at least a few hrs maybe overnite.
Also any transitions where materials are butted up to each other... lets say your tip fill is more than a few thousandths thicker or thinner than your core where they mate together, that will create bubbles as well, as your pressure system will only squeeze down to the highest of the materials in that spot, and will create voids. Or if your sidewalls (if you're using them) are too much thicker or thinner than your tipfill where they meet, or your core... all these materials have to be toleranced pretty tight.
Hmm I may try to prebend it next time. If I switched to a pneumatic press that wouldn’t be an issue right? It’s just vac bags are lacking in pressure… especially since I’m over a mile high.

Wow, pretty cool that that works. If I still had my board I would try…. But my buddy was a complete dipshit this weekend and didn’t lock his ski rack… found all the skis (broken) but my board disappeared somehow… wtf.
