Next the cylinder.I stumbled on to this one night whilesipping on several brews reflecting my thoughts for the day.What if I said to myself,why not try --so I did .
I've got a Hardinge -Jorgenson 5C collette chuck that runs dead on .Using a piece of cold roll and screw on nylon arbors it cuts dead nuts .I make the arbors just short enough that the chamfer can be cut in the same operation .The arbors of which I have several are tight enough in the bore you have to tamp the cylinders on .
Shown is a 200T cylinder .It dawned on be I had no way to measure because it was so tiny so I used a snap gauge and a set of 2-3 mics .Half azzed but it worked
