Platform Stepper Motors.

Posted By Jim Schneringer

Thinking of building a platform for my Hardin 12" Dob.

I figured out the dimensions from the yahoo group excel sheet.

I'd like to do a drive system like on the Round Table platforms. I have been cruising ebay for steppers and I'm just not sure what I'm looking for. Seems something around 12V with >120oz torque, 1.8 degrees steps.

Then what do I do for gearing?

I figure my north board is close to a 26" radius for my 40deg latitude and the scope weighs around 80lbs.

Any advice would be welcome.

DBA Astronomy products

Make that another very positive experience with Dale at DBA. I have ordered from him three times and all three times have been a been a joy. He has great support and he runs a very honest business.

A couple years ago I bought a Hardin 12" from him and he gladly answered all my questions, phone calls and emails.

I recently ordered a GSO dual speed focuser for the same scope and found out the too good to be true price was a price mistake. Even though it was an error on his part he honored the much lower price anyway and didn't say a word about wanting to collect the difference in the correct price.

It's the little things like these that make all the difference between a business that cares about it's customers and those that don't. Thanks Dale!

Wow nice details and still sharp.

Now if I can get my brian to switch from mountain mode to crator mode I'm sure I'd enjoy it even more. wink
