nope.I have the original cast iron pulley for my lathe, at the moment it has a 5/8" bore and I need drill it out to 7/8" for the new motor.
Do I have to find someone with a shaper or is there another way to do it?
Thanks
If you tell me the size of the keyway you need I can see if I have the right size broach to cut itnope.
You can broach with a arbor press and a broaching set
how does the how clamp stop the spindle from turning? I am picturing it spinning with the quill.I've used my milling machine as an arbour press a number of times. Lathe boring bar with HSS bit. Sharp bit, and small depth of cut, and it works perfectly well. The band clamp in the picture is to prevent the spindle from turning.
So you're shaving the keyway in a couple of thou. on each stroke, cool. That's how green I am when it comes to the possibilities of what a mill can do.I've used my milling machine as an arbour press a number of times. Lathe boring bar with HSS bit.

I need to shape the key now.
I have so many slitting saws now I'll need to make a few arbors... I'll make keyway versions since some of these saws are bigI made my own arbor too. I never bother making a key. I also never liked how much the arbour sticks out beyond the blade so I made it as a button screw that threads into the arbour. As long as the rotation tends to tighten the screw, I don't think a key is required. Then again, I never take beefy cuts.
Joe Pie has a nice design too. Might be worth a watch.

Did you modify that boring bar yourself or is that something that can be purchased?
I found these guys but their tools look expensive. https://cncbroachtools.com/
