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 |

Aw shoot. I had forgotten about this. I finished the drawings and sent them to Jeff Bowlsby, but this was during the week(s) when 914club was down and I never posted it here.
Anyway, I modeled two different diaphragms. One with the larger pleats, and one with the smaller pleats. Both were sent to me by Jeff. I don't know in what MPS's the different versions were used. I believe that the material used on the two diaphragms may be different. One of the clues to this was that the diaphragm with small pleats was highly discolored, and the one with large pleats was nice and shiny with no sign of corrosion or discoloration. For now, the drawings call out quarter hard beryllium copper, but that can change at any time. I think the initial purpose of this exercise was just to define the shape of the diaphragm for quoting purposes. PDF's of the two drawings are available here: MPS diaphragm, Large Pleats MPS diaphragm, Small Pleats Demick |
