Dial indicator mount for test stand

This allows a rear mounted dial indicator to mount on to the end of the rod on a magnetic base which has 9.75 dia rods. I got both items second hand and the base was missing the gauge mount.

Some dial indicator mounts use the stem but using the rear mount adds one extra degree of freedom.

Hex is to suit M5 x 20mm long hex set screws, I use thumb nuts on the other side.

The clevis for the dial indicator mount is 6mm wide, the rear mount on the dial indicator is 4.9mm.
