Dobsonian Navigation Knob

Hi Guys

I am after a source of a navigation knob for my Dobsonian.

It is the knob you use to move your dob in altitude and azimuth.

At present I have to hold the tube to move the dob which is not very satisfactory.

Any ideas where I could purchase something suitable?

Can I suggest you get a plastic handle as a metal one will get very cold in winter.  I sourced mine from Amazon if i remember correctly, it was many years ago.
