Ski Builders Forum

Most of the moulds that I have seen online are built out of MDF (medium density fibre board).
I have a bunch of 12mm chipboard plywood, would this work?
I was going to rip a bunch of it into 10cm widths, profile one side with a router and lament about 24-30 of them together for the mid section of the skis and make up tail and tip blocks.
I have enough material that I could make three or four different ski length moulds.
Any thoughts if this would be a suitable material to use for this?

I am assuming that by "chipboard plywood" you mean OSB (oriented strand board), correct?

If so, it depends on what type of press you want to use it in. In a vacuum press it shouldn't be a problem if you sand everything smooth. In a pneumatic press I would guess that the mould would crack under the higher pressure.

OSB, that’s what it’s called! I could not think of the name of the stuff.
I was thinking about a pneumatic press but at this point I could go ether way
Thank you for your input,
