Where to buy clock drive?

Hi!

Anyone knows how one can get or make a mechanism that turns exactly one round in 24 hours?

If anyone know, then I can start dreaming about equatorial platforms and rudimentary DIY equatorial mounts.

-Happy Lunar New Year-

Hi Chris
I will have an equatorial platform tailored for latitude 1-north delivered sometime in Apr, so you are welcomed to do some reverse engineering then.

cheers

tailored? actually can just buy from Sam Johnson what. His is already built for 0 degrees - 55 degrees

turns exactly one round in 24 hours

on most eq platforms, you'll need to manually reset every 45min to 1hr

Oh I bought mine from Mag1 instead.

Umm.....oh ic...Portaball will require a special one with a hole in the middle.

Actually dun need cos' I could have put the portaball stand on the johnsonian one but the one from mag1 is about the same price and shipping cost is lower. Sorry to Chris for hijacking his thread!

Chris, you can make your life easier by just buying a dual axis drive for a GEM to do your DIY platform. You will need to know things like gear reduction ratios if you want to make your own.

I was thinking of making one, but I have shelved the idea temporarily to design a fork mount with slo-mo for my 8" SCT. I have just submitted my drawings to a machinist for a quote. Hope it does not turn out too expensive.

Drop me an email if you want to exchange ideas on your DIY Eq platform.

lol.

Perhaps someone knows of some kind of very low rpm motor, that can be geared down?

Arief: your still need a clock drive that drives the eq platform.. that one needs to go round and round.

cc: I've been wondering about this talk of a portaball when I thought that Mooey bought yours, until I noticed (just) that you have a new baby.. gosh, pls share with us your reports and such!

Chris
there are websites with circuit diagrams for designing equatorial platforms driven by stepper motors. the parts shld be easily available from sim lim tower

the baby has not been delivered yet
