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 |

Sorry for a very delayed response from me on this with relation to the drawing for the diaphragm. I have been extremely busy lately and didn't get to spend much time on it.
Jeff B. and I did have some offline discussions during this time. Originally, I had planned on designing the boss on the diaphragm so that it would attach to the diaphragm with a threaded nut. So I was going to try and source an appropriate sized nut to do this. But Jeff suggested that we just replicate the original design rather than trying for the nut approach. I'm fine with that. But the diaphragm that Jeff sent me is a good one and he doesn't want it destroyed. And in the assembled state, it is very difficult for me to tell which parts are which in the pressed-together state. Here is what I wrote to Jeff regarding this: With the idea of replicating the original, it is very difficult for me to tell how it was assembled without cutting one apart. There are 4 'steps' to the center boss where the retainer is installed. It is difficult for me to tell which part is what, and if the retainer is simply a retaining ring that has been pressed on, or if it is a part that is highly deformed when pressed on (as in, the retainer starts out as a ring, but ends up with a step in it). Anyway, take a look at the images I have attached. This is one way it could have gone together. It involves four parts: the diaphragm, the boss, a washer, and the retainer. In this case, the retainer is just pressed into place (not deformed). Here is the exploded view I sent him: Attached thumbnail(s) |
