Source for focuser knobs?

For closure...

I wrote to focusknobs.com but never received a reply. I ended up
finding a number of short aluminum quarter inch "dowels" for lack of a
better term in my garage with the proper threads to fit the end of the
existing shaft. Ace Hardware had a plentiful supply of knobs that fit
the quarter inch aluminum dowel. I filed a flat on the dowel to
better secure the new knob's setscrew and voila... I am in business
with a very functional focus knob.

I have a Celestron SP-C6, a 6" f/5 reflector made in Japan. It works
well with a CG-5 mount,and it's a great public star party scope for
the Moon, but the focuser knob needs to be replaced. I tried Ace
Hardware but no luck. The knob is about 3/4 inch in diameter, is
threaded inside for the focuser shaft and also has a set screw.
Unfortunately the plastic near the set screw is breaking down and it
won't hold tight while the focuser is turned.

Does anyone know a good source for a replacement knob for this scope?
The shaft is quite small for the size of the knob.

Thanks,
