Say you are making a pulley from a piece of 4" dia. by 1" thick stock and you need to reduce 0.5" of the length to 1.25" to make a hub for the set screws. Is there a preference of long facing cuts or short axial cuts to remove the excess stock?

I don't know if it is the "right" way, but I do the facing cuts, and then clean up with an axial to the sholder, and then a final facing to square everything up.

In favour of axial cuts is that you can increase the spindle speed as the diameter gets smaller, to keep closer to the right cutting speed.

Having said that, I'd probably take the long facing cuts...

Which ever removes the most material with the least amount of manual work.It will depend on how difficult to hold also. Not much to grab on without cutting soft jaws or reverseable hard jaws. IMHO.

Use the compound and split the difference.
