Hi All,
I'm making giant steel washers for my bench grinder (one step in trying to eliminate vibration, and, yes, I'll dress the grinding wheels). These disks are 2.5" in diameter and I'm milling them to 0.250" thick on a manual PM-728VT. The next step is to mill a 0.625" center hole which should fit perfectly on the bench grinder axle.
Finally, I want to mill the outside diameter concentric with the center hole. The final diameter isn't critical but I imagine I probably need to remove 5 or 10 thou. I don't have a lathe, just the vertical mill. How do I mill the circumference? On a rotary table? If so, and assuming I now have that 0.625" center hole, is there a recommended way to mount this disk to the rotary table? Any suggestions other than a rotary table?
Thanks Everyone! Jim
