I have a 4 wire milliohm meter I'd like to modify for arm metering use.

Where can I find the copper/brass supports for supporting and metering arms?

Picture attached is of cap head brass nuts. This would work but I'd prefer something with some more height.

Hi Dave.  There's no reason not to use regular slotted round head brass screws such as these (*in whatever size and length you wish).  Just place them with the slots running parrallel to the arm's commutator, and the slot won't matter.  Just recalibrate after installing to take into account the resistance of the screws.

They kind of look like acorn nuts to me.  Do they have female threads?

Thanks John. That will work.

Don, they look like they should be.
