Once I buy a MkII (which is as soon as the empeg shop opens...) I'll make a try at making a wheel
in aluminum or stainless steel at my little lathe (Hobbymat) For better grip one would probably
want some sort of pattern... with a mill and a dividing plate it'd be easy, but as I don't have those...
But a friend works in a shop with a couple of CNC grinders. They're mainly for grinding circle
saw blades, but at least one can do really fancy stuff,
