I'll do a piccy when I get a second. I think that it is possible provided that the vacuum bag is not too slack, but hey, I've been wrong before!

b.

The underside of the plates is within the bag and subject to the vacuum provided that the bag has not completely collapsed onto the underside of the plate. This does mean that the vacuum bag can't be too loose otherwise what you say is true.

I think that you are right to use the mold and extend from that, but beany has a point which is that you would need a pretty massive vacuum bag...

...next year perhaps

B.

Mine are coming in at about $110 for a pair just for the materials cost. I had to buy everything from scratch.

I think that $100 is a fairly average target if you are buying small quantities.

B.

Through the hole in the end?

:-)


B.

Yeah - I agree that it would be important to avoid extreme tipping, but like you say this could be done by spacers that limit the plate movement, but don't interfere with the compression. I may think about this a little more.

B.

OK - it sounds like a contradiction, but the whole high pressure press thing has me a bit wigged out so I have been thinking up better ways to do it and I think that I have the solution: I can't post pics 'cos I am too useless, but imagine the following: 2 large area 'plates' which have a vacuum bag...

Still available,

I still have lots of 10mm ones, but am starting to run low on the 12mm ones now.

B.

I now have a stack of M5 (the right thread size for mounting tele bindings) inserts in both 10 & 12mm lengths available for sale. These are the all singing, all dancing ones with magnetic caps. Inserts will cost 30.5 cents each. For convenience I will give preference to larger orders as I want t...

You bring up a good point about modelling, and it really depends what you are trying to achieve. If you want to predict the final shape of a ski under a real loaded situation then this is fairly challenging without the use of FEA (though not impossible). The distribution of load along the ski will b...

********************************************************** UNITS: The Units for Youngs Modulus should be 'Pascals' abbrieviated to 'Pa' a Pascal is the same as Newtons/Meter^2 (or N/m^2) You will often find it quoted as MPa (Megapascals) or GPa(Gigapascals) 1 MPa = 1,000,000 Pa 1 GPa = 1,000,000,000...

yes that is correct

Thanks for the info regarding the vectorply. You can change the weighting of the relative strands by changing the equations - if you look at where the final youngs modulus is calculated it takes the average of the 3 layers. If you multiply the weighting of the 0 degree layer by 2 and then divide by ...

Hafte, The only time I spent checking was that the equations were correct - all the figures that I put in were just grabbed from the nearest place - I didn't take any time checking that the values that were in there were really accurate as I assumed that people would want to add their own and to be ...

On average you are doing pretty well then.
