Hi guys,

Through a local DOD contractor I found a few small shops that will make Berillium Diaphrams...

Apparently the new fighter jets use alot of the material, so they are set up to work with it, and do small runs...

So , what I need, to get a price, is CAD drawings of the diaphram, and the piece that gets pressed into the middle..

I have been told that they can do it, based upon my description.

So, did anyone ever make a drawing of the diaphram...or maybe please......mike...could you...
