Re: Round Top skis 19/20

Better to start cutting and grinding after 1-2 days if there is no emergency. The epoxy needs 4-6 days to fully cure. Before that you can still influence e.g. the camber when flexing them too strong. Was written here several times....

Re: Soild Wood skis

What is you definition of a fully wood ski? No Fibres? Edges?

Tardi Skis did that in the past, dont know if they still build like that

Hello Mike!
Maybe you could enable https for the forum, more and more browsers spit out warnings for non https sites.

Re: Round Top skis 19/20

What also helps is to glue a piece of waste wood outside of the abs/pu. Like this the topsheet and fibres dont kink down over the edge and resin gets sucked out more easily

Re: Round Top skis 19/20

You created a resin trap. Topsheet folded over the side works good to keep resin trapped with vacuum ;) One solution is to have the fibres still sticking out so the resin can flow along the fibres to get sucked out.

Re: Round Top skis 19/20

Dont know the resin you use, but if it needs heat to cure you did create a half cured ski on one side (45 degrees....).

You dont necessarily lower the temp on one side to get camber, you can change your timing too. So one side kicks in and hardens up before the other side does.

Re: 3d Base questions

Vacuum. A 3D fixed mold for a pneumatic press is complicated and expensive. Or build it like a surfboard, it has been done as well.

Re: Vertical Fiber in Cores

I think the main reason for the industry to do that is to counteract the weak quality of cheap wood core production. And for marketing ;)
