3D Printed Lapidary: Cabbing Machine Assembly

Aug 2026 update: We've made a profile on thingiverse where we will upload these and more files. https://www.thingiverse.com/gemmakerm... Mike Zinski demonstrates how to assemble the cabbing machine he designed, with bonus tips and tricks. If you are interested in getting plans for FREE to print the machine, contact Mike at gemmakermz@gmail.com. There is no fee or newsletter you need to sign up for. Here's a list of the majority of accessory equipment you might need for the cabber. This list is meant to be instructive, not prescriptive. Some parts may be unavailable and you will need to find another source, or maybe a better source. Don't forget bolts, nuts (if desired), and wiring if needed, and laps if you don't have any. Bearings: (22mmO.D. X 9.6 I.D.) (7/8" O.D. X 3/8" I.D.) same bearings used on all cabbers, and saws accept 10" saw. https://www.ebay.com/itm/303030096933 Green belt material: cut to length and weld together in alcohol lamp flame. 6 mm or so should work. https://www.ebay.com/itm/165958460310 Water pump used on all cabers. https://www.ebay.com/itm/253979919126 Tubing is aquarium tubing and the valve aquarium air valve. Patrick's note: this pump doesn't have much oomph so don't try and use it to pump from the floor to a bench. We're still trying to find a motor readily available to power it. Been using 80 to 90 vdc Speed controller: https://www.ebay.com/itm/357531026389 A member used a bike/scooter board motor that's a 24vdc motor 250w plenty of torque, he use the control box but opened it up and adjusted the high end trim pur to it lowest output voltage (about 48) and turned dial for max only half way. Used on small cabber. Patreon:   / donohuelabs   Etsy: https://donohuelabs.etsy.com/
