Pulley Balancing

[CV355]

Has anyone here machined their own pulleys?  Aside from what you'd consider is "typical" for balance straight off the lathe/mill, did you need to do any additional balancing?  Any recommended method?

I would think as long as everything is indicated in then it in theory it should be zero balance.  We used to take 1" wall tubing X 16" long and after turning the OD, indicate it in to .002 and bore the ID.  Ended up zero balance every time.

That's what I'm thinking as well- shouldn't be any issue on the main pulley I am designing.  But, the secondary piggyback pulley needs to have a feature to locate on the primary- can't have a pin or key on one side without balancing the rest.  I'm thinking stainless shoulder bolts will work, and I'll just have an extra 0.002" on one of the three mounting holes so it doesn't overlocate.  I may be overthinking this a bit, but then again I have seen what a bench grinder can do if it isn't balanced perfectly...
