Well I found a unitron electric pier drive or shelf drive brand new in the box. It would replace or go in place of a weight drive. I do not have the linkage and am wondering if anyone has a closeup shot of the linkage and 90 degree box at the worm drive I am tring to figure out how I am going to make this baby work on my 152 mount Any direction would be great Clint So hard a caveman cant do it!!! :tonofbricks:

Hi Caveman,
Scott Losmandy has a 5" Unitron with weight drive and linkage. Go to the Losmandy web site and either call him or call, he *may* be able to help you out. Here's a photo of the drive. Good luck to you sir!

Are you quite sure your electric drive goes on the shelf
and is not direct-drive? All Unitron electric drives I
have seen are direct-drive to the worm gear. But maybe
there is some gap in my knowledge. Ones I have seen are
small black box with mounting screw in the bottom.
Output shaft is on the side with a pivoting arm.

Hi Bill,
Yes it is! A classic weight driven clock drive. The only power it requires is a suspended weight and it will run for 2 to 3 hours and quite accurately as well! :)

Those true "Clock Drives" as they were called will only become more and more treasured as time goes buy...no pun intended.

Thanks Robert I will talk to Scott. Those are the exact parts I need to make this bad dude work. The drive i have is avertised as a eyepiece shelf electric or electric pier drive and it is brand spankin new so if I can get the linkage made it will be unique! I found a 90 degree drill extension that I can make work until I find a guy like scott to make a copy of his! LOL
