I’m in the process of building a 2″ x 72″ belt grinder powered by the permanent magnet motor from an old treadmill. The business end of the grinder is a pair of rollers and platen that supports the sanding belt. I milled these out of some 3/8″ steel plate
Damn! I’m bluing everything from now on!
Interesting! That discoloration is evidence of a ground off weld telegraphing through the heat bluing!
I call this look “Blue Steel”.
Now to figure out the mount.
It’s starting to look like a grinder!
They predicted a foot, we got a foot. #science
Learning that deeper not faster is way.
