DIY Simple Slow Motion Controls for Zhumell Z8

[Squints]

After studying a variety of DIY ideas for slow motion controls, I came up with my own pretty simple design that only cost me $110 in materials (plus tax).  Once I had all the parts collected it only took me a day to assemble it on my Z8 Zhumell. For the azimuth drive I pretty much copied other direct drive systems I've seen online, but I used a monopod to create the altitude arm and attached with bimini hinge brackets (boat awning deck hinges). It works like a charm.  Will gladly share my parts list, assembly photos and notes with others.

Hey Squints! I’d love your parts list and instructions. Your neat innovation might make my 10” Discovery dob more fun to use! CJ

Hi Squints, this looks really neat! Would love to add this to a dob base im making for a 4.5 reflector. By any chance you still have the parts list and assembly pics? 😬

That's a great setup do you have a parts list

To move from a higher altitude target to one nearer the horizon would take an eternity screwing the adjustment ring ( unless you fitted some sort of release mechanism or clutch.

The altitude screw is fixed into a monopod leg, which has quick release locks between sections.

Very nice tidy job I see you have a quick release pin ,I have made a similar part in the past more for making a long focus refractor on a Eq mount more stable I'm sure your design will help in this way also. Nice job👏
