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... Rich |

I will do the CAD models in Solidworks. I can output most any format that shops can import. Most likely, they will prefer a 3d IGES or STEP file. They can also simply work straight from the drawings I will create and skip the CAD models if they choose.
I've read the patent documents. I have them at work and can take a look at the material - but extremely unlikely that it will actually have a useable material callout and hardness. I believe that heat treatment is done after forming. So we have the option to have some diaphragms made and then heat treated differently. 1/4 hard, 1/2 hard, 3/4 hard. They we can make a simple fixture to pull a vacuum on the different diaphragms and compare them to stock to see which one most closely matches the stock movement. Be sure that we include Patrick in this. He has a great shop and does great work and is an honest guy (as well as a 914 guy). He knows what he is doing and will give us the lowdown without any BS as far as the mfg and tooling of this. Demick |
