I am looking for a wall plate *similar* to this:
The actual plate would be:
- support a "keystone" connector "insert"
- recessed connector area
- "mushrooms" onto which to mount the phone
The "zinger" requirement is that I need the mushrooms to be located2.75" apart instead of the nominal ~4". [To put this in perspective, imagine those in the illustration being located just *inside* (vs. "outside") the faceplate mounting holes. They don't make such a beast.]
I can probably approximate the traditional mushrooms with a regular rivet. Or even a #8 PHMS.
But, fastening it to the stainless plate is the challenge (and doing so in a cosmetically appealing manner!).
There's no meat (thickness) to the plate so you can't really tap a hole. As such, a screw would need nuts front and back to wedge it onto the plate. The nut on the front would interfere with the back of the "phone".
A rivet could work if I turn down the shank to a smaller dia thus making a shoulder to rest against the front of the wallplate. Then, peen over the turned portion that protrudes through the plate to the backside. E.g.,
| | || |) ||========_)) ||======== )) || |) | |
A copper rivet (soft) would probably not be objectionable.
Welding would be a cosmetic mess.
Any other approaches I could consider? Or, a source for the mushrooms/rivets with that sort of side profile? (which would obviously be targeted towards this sort of application -- to ensure the shoulder was at the right height!)
Or, a way of removing the rivets from an existing plate that would allow them to be "reused"?
