Meet Pinhead!

@antron007, Im no where near to that phase yet but I will need the parts later on. I haven't bothered to price anything yet but I will have to have a design first Im sure. There are a few forum members here that have done some pricing so they may give you some advice here.

@Troy Cool, thanks for the info.

Here's a short clumsy clip of my waist articulation idea.

Does anyone have experience with a different swivel bearing that's more stiff? If you look in the video there is a bit of a wobble that will show up during drive.

@Troy

Good progress. I like the body tilt idea. I will see if I can help you find a better bearing than the lazysusan. What are the dimensions of the one you are using?

Great update! I have built a few alt/azimuth telescopes in the past that use a similar bearing type, using UHMW Polyethylene Plastic Fabrication Suppliers . 3 square pieces 1.5 inches separated at 60 degrees attached on the bottom platform and a " nubbly" formica/arborite on the top body. These were ultra smooth and very easy to turn! Of course the 3 pieces were thick enough to countersink a screw. Glen

Nice work Troy.

As far as a bearing I think you need a higher quality one. Lee Valley has different sizes of top quality lazy susan bearings that wont totter like that. They have 3" up to 12". Follow the link below and good luck!

Thank you guys! I'm sorry I didn't have the head and arms on it. @Dave I remember that site from a past post. The one I have is like this from servocity. They look like the same ones. Would you advise using the 9" round ones versus the 4" I have now? Perhaps the design is different internally. UPDATE These had too much play in them to work for me.
