Making a homemade mirror grinding machine ATM,
#0183;#32;Anything bigger and I would most certainly put the quot;bridgequot; back up and do the 70% grinding and polishing. With a full sized tile tool, pregenerated curve on my quot; I went from 60 grit to polishing stage in 4 hours. Polishing took 17 hours so any polishing on a mirror 10quot; and up I think would do quite nicely from the bridge.
