Anyone know where I can get my brake drum turned in the Chicagoland area?

Do Bullet drums have the density to be turned? Is the hub un - spoked so it could even fit on an automobile brake machine? Why not replace the hub?

There are not specs that I have ever seen to suggest that this is a good idea.

So, what do you do when you relace the hub and it pulls the hub out of round?common occourance is it not?

  My first bike was a 1966 Honda CB160. I have never heard of anyone turning an MC brake drum or cutting down a disk. Bike brake drums and rotors are not built to last forever. They are built to cut down on unsprung weight.
"relace the hub and it pulls the hub out of round?" I believe the answer is loosen the spokes then tighten them up with the wheel spinning on a wheel building spindle. As you try to tighten the spokes, you will have to constantly check for axial and radial run out.
  My other bike is a Honda ST1100. I don't miss spoked wheels!
