I need some help if possible. I recently purchased a 15x30 Servo shift lathe. It needs some cleaning and a few repairs but overall it seems to be a worthy project. I want to know as much as possible about this lathe. I plan on doing a restoration before placing into service.

I have a copy of a copy of the leblond regal 15" and 19" instruction and parts manual but was wanting more info on this machine if possible. I would love to have detailed electrical schematics on this machine. I know Leblond LTD. has parts and manuals but I wanted to try here first.

Are there any members who have this machine now or know of a good source of manuals for it?

I know the stories on how troublesome the servo shifts are, but there are not a lot of choices for lathe purchases in this part of the country, so i'm going to give it a try.

Any information would be appreciated. I know we used to have a member here that worked for Leblond but can't remember his name! Sorry about the photos not being clear.

Nice lathe. I'm a big fan of LeBlond and would like to get one some day. I think I saw that one on eBay... Congrats.

LeBlond still sells parts for a lot of the Regals. Check here: http://leblondusa.com/

Thanks Ray. I have been to their site, and had a phone conversation about the lathe.

I would think there would be an abundance of used equipment in your area!

The machine was found locally. I have been looking for a Leblond for several years now. Hopefully the hunt is over!

No, not much equipment like that around here at all. If I go North, it can be found. Personally, I think Leblonds are king of the hill stuff in terms of industrial equipment. But don't be fooled, they're darn accurate and precise. I used a 15x54 for a long while. Very solid and well tuned machines. They were top dog in their day and my father and uncles used them almost exclusively throughout their careers. The only downside is that most of the ones available have seen heavy use and need a full work-over. Most of those machines ran 2-3 shifts per day at least 5 days a week.

Good luck with it and please keep us posted.

Nice find, David. Looks like it will clean up nicely. I believe the made a number of those, so finding a manual or parts shouldn't be too big a problem. Keep up the pictures!

Thank you Tony. It will be several more weeks before I start on the lathe. I will try to document the project!

If it is like my 1953 13" the bearings in the head stock have to be oiled before you start it up. So they aren't dry mine only has a splash oiler system.

Thanks for the replys Paul and Steve.

I'm not sure on the pre-oil before start up Paul. I have not read anything stating that it is required, I will check on that.

Steve as I get further into this build, I will give you a call to discuss the servo shift and the electrical controls.

It appears that some of the original components in the control panel have been replaced and possibly upgraded. So my first task is to see what the machine was suppose to have originally and compare that to what is actually there now.

In the photos below you can see where a transformer has fried at some point and the circuit board does not look period correct to me.

I will try to update as I dig further into the machine!

The servo shift system is great to work with when it works ..... But for about $357 you can convert this to a manual shift and never have an issue with the electronics ever again :) Leblond sells a kit to switch it over. The biggest fear is a failure with the shifting cylinders and having it drop into 2 gears at the same time causing damage.

--jamie this is mean't as a note --my leblond operates like this. the control handle that controls the spindle rotation and direction is mechanically connected to a five position drum switch. lets call the middle position ''OFF'' MOVE THE HANDLE to the next detent and this is the ''brake apply'' position --move even further and this will turn off the brake apply circuit and send power to drive motor and spindle will start turning in one direction. now go back to neutral or ''OFF'' position and -spindle will stop . here we can move handle in opposite direction --note there should be a mechanical inter . lock which you will have move out of way before control lever will move in opposite direction . go to first detent and brake will apply then to second detent and spindle will rotate in opposite direction. guess that's enough confusion for now -there's a little more to add later but that is the 5--positions which i have on my le leblond. servo-shift . hope this helps for now . steve in mt.
ps - pls. call if u have any ques.
