Design files to create ball bearings from 6mm airsoft BBs or 4.5mm steel BBs!
The machine design is meant to sand the 5mm plywood down to a thickness of 4.5mm to fit the smaller bearings. The design uses the 6mm bearings to move the sanding head. The majority of the project is built using 3mm and 5mm plywood and cut on a laser cutter.
The basic single ball bearing was designed using OpenSCAD
The machine and PCB layout were created in Inkscape
The schematic and breadboard layout is done in Fritzing
- Algorithm to cut sandpaper as a continuous piece based on the diameter and length of the sanding head
- Adjustable motor mount that attaches to the base
- Ability to clamp the machine to a table
- Simpler construction
- PCB Circuit
- Push Stick for sanding materials
- Measuring device for setting the infeed and outfeed tables
- Customized bearings
- Readout for speed, rpm, control position
- Fuse, switch, circuit safety
