Does the rubber act like a miniature fire hose in this situation and absorb error in the top mould? If I made the top and bottom moulds exactly meet then used a 20mm thickness of rubber wouldn't it compress to 18mm at the tip and 8mm at the centre (given 2mm ski tip and 12mm core centre thickness) a...

Sorry to dredge an old thread. With this hydraulic pressing method people are saying the top and bottom moulds have to be perfect. The bottom mould I understand is like any other bottom mould.

My amateurish thought process suggests that once the ski materials are laid up on the bottom mould that the top mould would then not exact...

It is capable of over 100 bar pressure, but can be lowered without hydraulic force being added. The weight of the top part of the press I have been told is about 30, 000kg (30 tonnes, 66000 pound...
