I was making some threaded collars tonight and one of the steps was to cut a 3/4-14 internal thread. It's so much different than cutting threads on other lathes that I thought you might enjoy seeing the process.

That's pretty slick Tom!
But with my right hand -left hand spasticity I'd have a crash well before the thread was to depth.
I've used the Hardinge HLV-H toolroom lathes and their super-slick threading before. I'd like to believe that there's nothing easier for manual lathe threading, but I've never run a Monarch 10EE. I believe both machines use a dog clutch mechanism. I do like the HLV-H a lot though, it's a well thought out machine, high quality construction. Robust cuts aren't going to happen, bu for the intended purpose it's quite a nice machine.
Nice video, thanks for putting it together and posting it.
One other feature I forgot to mention is the auto stop. You can set it to stop the tool when threading to a shoulder and it will stop within thousandths every time (even with a spastic hand). It's a bit scary to use the first time, but once you get over the initial terror of threading full speed to a shoulder or the chuck hands off, you'll wonder how you ever got along without it.

Ken pointed out the retracting lever when we visited the L.S. Starrett plant in Athol, MA and I thought it was a cool feature. This is the first time I have seen it in use and I am really glad you took the time to put the video up Tom. Of course, I have seen that particular lathe in person but both Tom and I were enjoying one of his home brews, so it never got fired up.
Tom,
Really slick and quick

+ 2 tom Oh for a lathe of that quality
Perhaps I could say

Hi
Tom
Nice video clip
I have never seen a top slide like that
Top quality lathe

Tom,
Thanks for the tip about cutting steel threads by advancing the compound versus cutting Delrin threads using the cross slide. I did not know that about Delrin but it makes good sense.

Nice... I have a quick-withdraw too on my Holbrook (on the cross-slide, which has two sets of dovetails so taper attachment and power cross-feed are independent), but for no readily apparent reason they left out leadscrew reverse on the model C... All the other Holbrooks got it :( I have to rely on the VFD and transmission brake to stop when threading, Dammit!
I have a cunning plan to add it, it's getting the stops to work (without a horribly complicated mechanism) on threading that has me stumped...
