Clock Drive for Old Edmund Scientific Reflector

I have a cherished 25 year old Edmund Scientifc 6" reflector still in
excellent working condition, and I'm thinking about adding a clock
drive to it. I believe Edmund offered a clock drive as optional
equipment. Anyone know where I might obtain one today, or whether a
modern-day clock drive would work on the equatorial mount pedestal?

The manufacturer's version may no longer be available, except by extremely
good fortune. IIRC, the Edmund clock drive consisted of
a slow synchronous motor (AC), a worm / helical-gear pair, a mounting
bracket, and some hardware to form a slip clutch to mount on the end
of the polar axle.

One trend popular many years ago was the tangent arm drive, which was often
jury-rigged out of available hardware. This would likely
be the most promising way of achieving your goal.

Cheers,

Thanks Larry. I'll do a search on the net and see if I can come up
with any info on a tangent arm drive.

I appreciate the input. It'd be good to see this ol' classic able to
track stars, perhaps even pull off a little astrophotography in its
old age.

Fleemo,

I do not know if this will work (obviously you would need to get the
other parts), but surplus shed has the meade motor for a EQ mount for
19.95

Good luck with your search.

Clear skies,
