Beseler 23C II focusing knob broke.. Help!

[Jim17x]

I just went to make a print and noticed my focusing knob and shaft just freely spins and i cant focus now. Can this be an easy fix or should i just toss it in the dumpster and buy another one since they are so cheap? Below is a photo of the knob and model # plate.

Thanks.

The setscrews that secure the drive wheels to the focus shaft have likely loosened and need to be tightened.

See the drawing on page 6 figure 11 under “Adjustment for Condenser or Focus Setting”. The parts “B” in the drawing are the drive wheels and their setscrews.

Note: The same drawing serves for the upper condenser adjustment and the lower focusing stage drive mechanism.

toss it in the dumpster

Maybe, just maybe, you could offer it to someone who is capable of performing a simple repair.

No Bernard.. I'd rather toss it in the dumpster than turn 2 screws. I might not be capable of turning 2 screws. Maybe, just maybe..
