Your lathe has a ward-Lenard drive. This is a signal amplifier that uses mechanical components to amplify an input signal. A true marvel. It creates a DC voltage to drive the main motor. Otis used ward-Lenard’s in elevators well into the 1980s!

That is pretty fancy Chuck. Those guys know how to make a lathe. Thanks for the plug for the discussion.

Thank you Chuck. Those are sweet Lathes. Thanks for showing more about the ELSR. Gary

Nice . Some great features on that lathe . Cheers .

This is the first 10EE with ELSR that still had the control on the headstock. Every ELSR machine I've ever seen had the headstock switch removed and a blanking plate installed. Coincidentally, I just tore the ELSR housing off my 10EE completely apart last night (less the knob on top - can't get it off) to strip what's left of the burnt-off paint, thoroughly clean & remove any rust from the internal parts, and prep. it for Bondo and paint. My 10EE was in my brother's garage when it burned to the ground. He died before he could submit everything to his insurance company. I don't have the $65,000.00 that Monarch quoted to repair the machine so I'm stuck doing it myself. Arrggh, there is little I dislike doing more in life than bodywork and paint. I've repowered it with a 3.5kW AC Servo motor and drive. It also allowed me to add a true Electronic Lead Screw Reverse to the machine using 2 proximity switches tied into the axis overtravel inputs on the servo drive. With moderate spindle speeds and mass the spindle will stop in 1 revolution or less, typically stopping within a thousandth or so. I could lower that figure by using high precision prox. switches instead of bog standard ones. I'm really looking forward to getting the old girl brought back from the scrap pile, hopefully by this spring. I wish I had the time to document the process with video but it's simply takes way too much time to be setting up cameras and lighting. I've been picking at it for about 2 years as it is, and I really need to get an operable lathe back in the shop. Till she spins again, all I can do is live vicariously thru other's 10EE video's on NannyTube....

repeats within .0002" seems good enough to me. A bit fancier than my Monarchs.

Some cool features on that machine, kind of interesting that they run a generator off the main motor for accessories

Chuck, Many thanks for this video... this 10EE has lots of functionality I was not aware of... Any more videos on this 10EE would be gratefully received. Take care. Paul,,

See you at ARW

Very. very nice machine. Any Monarch is nice, but the !0EE is extra special. Enjoyed the explanation of the threading system overview. Always learn so much from you, even when Charlie interrupts. Take Care and Stay Safe. Bob

Beautiful piece of equipment Chuck, I can see why so many owners have re-painted in bright colours. I am overwhelmed by the width of the saddle .it sure spreads the contact over a large area. That stopping feature for threading is super slick as well. Enjoyed , cheers!

The feature only stops the spindle mechanically with the dogs camming the apron spindle control lever to neutral. The DC spindle motor quickly dynamically brakes to a stop when in neutral. The larger Monarch lead screw reverse option is all mechanical, the spindle continues to run through the cycle. Great video!

The trick with the cross feed dial is in setting up for threading. Set the compound to 30 degrees (or a little less) and the dial at zero. Start the lathe and use the cross feed to advance the tool to the work with the stop engaged but the dial lock (lever in front) unlocked. The dial will come up to the stop at 0 but will continue to turn with the dial slipping. Advance the tool until it scratches the work and engage the dial lock. At that point the cross feed and the compounds are both at 0 for turning threads.

Those are some serious machines. So many flat spots for a mag base! Ahead of their time 😊.

I would love a follow up on cutting multi start threads on the 10EE ELSR. Have you ever cut a three start thread and do you know if its an easy adjustment on the monarch? Cheers from Australia

10:44 It's actually 4 10ths out as it's showing -2 whereas the first time it showed +2 10ths !

I don't think that I ever saw a lathe that size with that large of a carriage. Was the electronic lead screw reversing a option?

Another item I need to buy!

Hi, I'm really amazed by that threading stop on the crossslide handwheel. How does it work that you have a defined stop in both directions? Looks like that is really helpful for cutting threads. Never seen something like this on other lathes. Thanks for sharing.

Always wanted one....... what does it weigh. Not often you could improve a machine and decrease your footprint in the same swapout.

I've yet to see a full tour of the 10EE having been made aware of them by Keith Rucker (VintageMachinery.org YT) and it's clear it's an oddball lathe. Keith has one to fix with an AC/DC system but he says electrically it's a mess. Keith may well appreciate some assistance in getting it fixed up in due course. I noted your dehumidifier. Do you have that connected to a permanent drain ? Odd how the text lines above have been truncated like that - nothing to do with me - just pasted the text there!

Chuck it looks like a little bit dirty down there Thanks for the quick video

So frigon nice I want a 10EE!😣 Maybe you could buy me one for Christmas this year buddy?🤢😣

Cool machine!👍🏻

Nicest lathe I have ever seen.
