I need to make, buy or beg a small number (half a dozen will do) of copper washers, 1" x 1.25", thickness not critical, I need them in the next three days or so. Any suggestions? I've got some 2" dia 'copper' bar, I thought of turning them from this & parting off but it's the most evil stuff I've ever tried to machine. I could probably knock up a pair of wad type punches which would do to knock them out from sheet by hand, but achieving concentricity might be a problem. I suppose with numbers that small it wouldn't matter too much if I had to make 20 to get 6 good ones
TIA
