It doesn't have much
runout, especially when you compare it with die cast step pulleys.

If you'd learn to rough your parts before finishing, runout would be a thing
of the past (assuming you used proper machine procedures, that is!). It
is not good practice to machines parts to size on one side, then turn a
second side, especially when removing a lot of material. Good policy
dictates that you would leave about .05" on the surfaces for finish
machining, which would remove any runout you would have from stress
relieving. It also helps prevent damage to your work because finishing
operations tend to be much lighter, thus demanding much lighter chucking
pressures..
