1" Bore Timing Pulleys

[asid61]

Opening up the bore on a pre-made pulley can be done on a manual mill relatively easily with a boring head. Just indicate the pulley bore, put the boring head in and bore it out to 1".
On a lathe the operation would be pretty similar, I would think, except you would not need to indicate.

As a side note, swerve drives do not require CNC capabilities provided you are okay with a small amount of added weight (due to less pocketing).

Or people with a lot of free time and some decent skill.
