At the 2011 Jamestown/Greensboro Fall Sawp Meet my good friend Clare gave a couple of small O'Scopes. One of them was this

neat little Millen unit. It has a 1" CRT and is made to panel mount.

Included with the scope was a plastic bag of crumbled up black plastic pieces I was later to discover were he remains of a part that held a pot and connected it to a knob on the fron panel.

I used a wire tie to hold the 2 main pieces together so I could take some measurerments.

Looking through my junk parts boxes I found a piece of round aluminum rod that I thought I might be able to use to make a new part.

Here is a view of the scope with the new part installed.

Here's a close up of it, it had to fit the knurled parts on each end for s pressed fit and have an opening to allow for thghtening the 4 set screws that hold the 2 shafts.
