When I went 3 phase and VFD on the lathe I tossed the drum switch. I still flip the belts around and tend to leave the VFD at 60Hz but there are times where it's handy to just dial down or up the speed a tad. And there is a reverse switch if I want to risk spinning off my chuck and sending it across the room.

How do you adjust the backlash on the cross slide leadscrew?
Three phase wasn’t in the cards. $600 all in. Not happening.
No idea. I haven’t pulled out the whole assembly. That’s not even my lathe. Just one like mine.

Did you check if it was just the capacitor on the old motor? If it is, and the old numbers are still visible, it is literally a $20 repair!

We tested it at the shop. A winding shorted out.
I have a British 4 wire motor that can be reversed with a drum switch......
Got it wired up. I forewent the fwd/rev switch because the lathe has a threaded spindle. I never ran my South Bend in reverse so I have no reason to believe that I'd run the Clausing in reverse.
In other news, adjusting the spindle bearings made a massive difference in the possible DoC. When I was making the change gear bushing I was pushing the edge of chatter with a 15 thou DoC in 1.5" 1018 with HSS tooling.
With the adjusted bearings I can take a 40 thou DoC on 1018.

Thanks MIke, I appreciate that. Much easier to comprehend than everything I found.
My Emco V10P had a threaded spindle with a locking collar. I made a few backplates of my own with this feature as well. For those i used shaft collars, and they worked well. Being able to reverse the spindle is a must for me.
I did have a chuck fly off on me once as well, just shutting the lathe down, not even reversing and i guess the collar wasn't tight. It messed me up pretty bad.. ripped the palm of my hand open when i blocked the 5" chuck from hitting my face (would have been a tragedy, as my beauty is everything to me).

I don't know Darren. Looks to me like your face resembles the side of a pickup truck...
Oh, and before I forget...
Do you have any pics of those setups?
I do. I will hafta look. I think there's one in my thread somewhere.
Ya, there is a whole thread about it that I think you started......

Locking on a threaded chuck ?
Locking the chuck to the spindle has been discussed before. Here's one such thread....... In this reply Bob (@RJSakowski ) shows how his spindle has a groove to lock the chuck on: https://www.hobby-machinist.com/threads/thread-crest-override.40895/post-351007 here, I suggested a draw bar type...
