I would like to be able to turn the drums of several old motorcycle wheels after the stresses from the rim and all the spokes have equalized themselves. Although this would be very easy to do on a lathe, unfortunately my lathe can handle 16", whereas the OD of the rims to which the brakes drums are mounted range from 18" to 21". However, it would be easy enough to mount these wheels horizontally on the rotary table of my Millrite vertical mill using a false axle in the bearings to accurately center and align them. But, what should I use as a cutter to skim the drums? The surfaces that will be cut will be around 7" or 8" ID and 2" (max.) deep, and I'm guessing that no more than 0.02" would need to be removed.
There are no obstructions at the bottom of any of these drums so if there were simply a, say, 1/2" dia. end mill with cutting edges that were a bit longer than than "normal" (i.e. they would need to be 2" long) it could be used. However, is there a cutter better suited for such a job? Or, is there a better way to do this?
