Sep 06, 2018 I know this is not for production but if you take the time to do the setup I think you can get good results. I did not use a collet but chucked the stem in a four jaw with a solid stop in the spindle for repeatability. I was surprised how well they turned out. I guess my point is that I would rather do the setup on the lathe then a surface grinder.
Before you use your angle grinder, clamp down whatever you’re working on in a vice or on a workshop bench. Make sure the disc is going to be spinning away from you as wire brushes can catch and kick back. You can check the arrow on the angle grinder to see which way the disc will rotate. 2.
