Summit 19-4 x 60 clean, repair and rebuild.

I wish my lathe had a tailstock handle setup like that. What happen with the carriage hand wheel missing, victim to the accident?

Yes, that and the spindle activation lever on the apron were both victims.

Got a little time in the shop this afternoon. Put the tailstock and spindle in the electrolysis bath for a soak. Also got the compound reassembled. It almost looks out of place.

Fridays are usually short days on the ship so I got a good bit of time to in the shop today.

I got the taper attachment removed. It seems to be rusted to the dovetail slides. I'll save it in the electrolysis bath for my Saturday duty day and see if I can get it loose Sunday. Not quite sure how to it works but I'll figure it out.

I also got the cross slide off and it's soaking in the parts washer.

The rest of the day I spent degreasing them webbing below the ways.... In hindsight I should have rented a steam pressure washer and cleaned up this thing off before I got it home.

Cleanup has been going well. There was a rod coming out the side of the taper attachment that I had a tough time getting out. I didn't think it was a good idea to heat up that machined assembly. The sliding parts came apart after I soaked half of it in the electrolysis bath. Most of the major parts are stamped with a 584 which is the last 3 digits of the serial #. I thought it was pretty cool

The tailstock assembly is all painted and ready to be re-assembled once the paint cures a little bit.

I'm not sure if I should remove the apron or not. Is there anything too complicated about it? Thus far the disassembly has gone fairly well. Just don't want to get in over my head.

I'm waiting for the manual to tell me what lubricants to use in the headstock before I try to fire it up.

My RPC panel came in so I'll get that wired up. I need to replace the wiring to my outlet with 10ga for the 15hp motor on the RPC.

I got the 15hp RPC wired up and tested today. All worked as expected. Put the motor and control box on a handtruck to make moving it around easier. That motor weighs a ton! I was surprised that the 30A breaker didn't trip starting the motor. I had picked up 50A breakers and planned on rewiring that circuit in the panel.

I took the belt off the lathe so I could check the motor. It would not spin up using the controls on the front but if I manually pushed in the contactor it worked great. A little troubleshooting with the multimeter is in order once the manual comes in on Wednesday. There is a transformer in there that looks a little crunchy that may be the control voltage transformer.

Mine has interlocks on the doors, they have to be closed and the clutch has to be in neutral to energize the motor.

Thanks! I'll look at that. I didn't even look at the clutch because I had the belt removed.

Got the control transformer replaced today. That solved the issues with starting the motor from the front panel.

My next challenge is the headstock oil pump. It's missing.... I called Summit and a new oil pump is $1700. We won't be doing that.

I'd like to replace it with an external electric pump. I'll have to find someone to turn a small adapter to fit where the oil pump was to feed the clutches. The rest of the oil is plumbed to a distribution block and a tray that drips on the various gears.

Any recommendations on a pump?

I vaguely remember Doc Nickel over on PM/ HSM adding an external pump and filter to his large lathe (Springfield?). Might be worth looking him up to see what he used.
