Ideas for test hardware: - "Cheese plates" are basically cheap, little optical breadboards for camera gear. An easy and portable platform for building. - Plumbing "faucet extension adapters" are available...

Thanks to the promise of a kind donation, I've ordered the bearings listed above. I'm looking for a local supplier of the ebay threaded tubing and flange nuts, but I'll...

The "Generic Pipe Adapter" has an OD slightly larger than the ID of the bearings, so to grind down those threads, the old trick of spinning it with a drill...

I've realized that finding a cheese plate with a hole large enough to support this tube is not going to be possible, so I'm switching to using pillow bearings. These...

Starting to come together: 3D printed flanges (See the flange.jscad file) to hold the lasercut disk. Next I have to figure out how to mount the sensors. They will eventually...

It has taken _forever_ but I'm finally making progress on this again. I've switched to a metal tube which I had turned down by a friendly local machinist on his...

3D printed a pulley using the attached OpenSCAD design which is modified from this old script I wrote many years ago: [timingPulley-v5.scad.txt](https://github.com/user-attachments/files/19617975/timingPulley-v5.scad.txt) I have a super long G2 belt that...

Well, the stepper motor is mounted. I wasted a bunch of time trying to get store bought junk from China to work and ended up making a mount myself from...

A tiny bit of progress after far to long.  - The NEMA 23 stepper motor is mounted - A pulley has been 3D printed and mounted to the joint...

Finally making a bit of progress on the mechanical side (which I suck at) with a better belt tensioner. The small pulley needs to be better attached to the motor...
