Re: Need help identifying Counterweight shaft stop to buy

M Hambrick

Hi again George

It might be worth checking with Astro-Physics to see if they still have any of the machined safety stop knobs that fit the old counterweight shafts that used the 5/16-18 thread for the stop. The catalog number was MSSKB.

I bought one of these in late 2016 to use on my old 800 mount. The cost was $27.00. As with all things Astro-Physics, the quality is excellent, and the machined aluminum is much more durable than the phenolic knobs.
