1" Bore Timing Pulleys

For those of you making your own pulleys, what CAD files are you using?

That lathe should be able to handle that task with no problem. Is there anyone with lathe experience you can find? If not, PM me and we can go thru all the settings and tooling needed to slice off, face and bore your own pulleys from pulley stock, or to just bore out pre-made pulleys.

Cutting keyways, if needed, may be a little tricky but not awful. If broaches are not available you can use the lathe as a shaper.

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.
