Cheap milling machine spindle - BT30-ER20, air powered draw bar + Tear Down!

Well there is no going back now! The CAD was finalised and the step files sent over to JLCCNC for machining. They were impressed enough to sponsor me for some of the machined parts so feel free to have a look at their website using the link in the description box on YT. I've also put links to the GrabCAD site for the CAD model, and links to the GitHub site where I will add the code as it evolves.

Whilst we wait for them to be machined and delivered I thought I would make the control boxes. Enjoy!
