I've been able to tidy up a few of the hide faces on a normal bench grinder if they are not too badly mullered. Stinks the place out though.
I've also made a couple of replacement brass faces on my lathe, for when you need something harder than copper but softer than steel.
For Morgan wheel changing purposes, I have a lead hammer - came from a retired fitter in an explosives factory (the idea is you can belt the living daylights out of something without risking a spark)
Cheers
