50lb Al platter machined by a friend of mine. Polished carbide spherical bearing and neo ring magnets to alleviate the weight. I have to come up with worthy plinth for it. Thinking of DIYing Schroeder tonearm
Very cool project!! I'm looking forward to seeing your progress on this. I have been dreaming of building a DIY Schroeder type arm for years. It's not like I spin much vinyl these days, but I love the engineering aspects of tonearms. I built a crude uni-pivot arm years ago, but without access to a machine shop, a Schroeder type is just a thought process to help me get to sleep.
What do you plan to use for the belts (assuming you will have belts). I've been using 1/2 inch - matches the pulley - clear non-adhesive mylar tape. I bought a spool of it 5 years ago or so and both the spool and the belt seem to have been lost in my move a year ago. You would think 1/2 inch plastic non-adhesive tape (or ribbon, or ?) would be an easy Google search, but it is not.

Started 3D modeling for another version with 3 motors. Just a concept at this point.
You could also consider Panzerholz or phenolic(plus veneer).
