Hi folks:

I've got a question about machining a drive shaft pulley that I bought used. My main question is would this be a safe pulley after I've machined it (I've got a metal lathe)?

So, here's the pulley I've got: https://www.mcmaster.com/1405k32

Along with this QD bushing for a 1 inch shaft: https://www.mcmaster.com/6086k116

I want to bore out the pulley to use this QD bushing instead (for a larger shaft 1-7/16 inch): https://www.mcmaster.com/6086k849

The larger QD bushing normally fits this pulley: https://www.mcmaster.com/1405K52

The larger pulley is thicker but is the same OD. It also has larger bolt holes at 1/4-20 instead of 10-24. I do have the option of only doing 3 holes - either threaded or pass-thru. Ideas and suggestions?

I'm not going to be flying with this pulley, I just want to use it with the smaller used redrive I bought for ground test stand prototyping purposes.

Thanks for your thoughts, Michael
