Final Build converting 120V single phase bench grinder to variable speed belt grinder using a VFD

Heya, easiest way to compress the spring to change sanding media is to just squeeze the belt. Easier than pushing down on it.

Do you sell those angle guides?

Hi Jim, I don't anticipate selling any of these. These are simply prototype 3D printed parts using materials (magnets) that I have kicking around. Secondly, I think that every multitool will have angular variance between the shield and platen angle. Thereby eliminating the possibility of commonly produced guides.

I received a notice that Glen placed a comment but have no idea where it is located. The notification read "Glenn commented: "Curious, have you plugged a Kill-A-Watt in to see what your Watt/Amp draw is with this configuration? I'd be curious to know what your reading are."
Glen, Here are the various readings based a no-load free running speed.
