Yes. It looks like a real Goldberg contraption but that sounds and looks like you are right.
I've a 13x42 DSG; they are called the Rolls Royce of lathes, a not undeserving title. I waited for years for one come up and pounced within hours. It was originally sold to Uof T in 1968. Its the lathe I use more than any other. The bed is hardened and is automatically lubed when as the carriage is moved. This keeps where to a minimum. i re-scraped the cross slide and compound.
A 13x42, lathe that weighs 5200 lbs and is 7.5 HP, they are a treat to use. It cuts imperial, metric, diametrical and modular threads right off the gear box. oil clutch, spindle mechanism to do up to 8 start threads, and everything is oh so solid. I once did a 1.3125 DOC in steel, .004" /rev just to see....and you couldn't hear it slow down.
The only think I don't like about that one is it looks like it has the built in 4 way tool post setup vs the preferred imo compound with the T slot that can be adapted to any tool post. Might have to rework that, not sure what is involved.
There is only a handful of lathes in their league, as a make, highly recommended.

Surely that is a typo......???
You must have been using a VFD to do that! LOL!
Sorry, the devil made me say that!
Don't call me Shirley
I won't say it was a bright thing to do, pressing things is not the best idea, but at the time excitement to try it eclipsed good sense....fortunately the DSG didn't mind at all. Ground a great big chip breaker and gave it whirl and it made big funny looking chips.
I may start a thread on my adventures with the DSG, I have photos of it, but don't want to derail things here
Just to be super clear. I was purely having fun with @Mcgyver.
Just for poops N giggles, I did a 1 inch cut in soft steel on my mill a while back and even posted a video of it on here. I seem to recall the depth of cut was around 20 thou.
Like @Mcgyver says,it wasn't the brightest thing I ever did but curiosity is a powerful motive for me.
Not the same as a lathe of course, but nonetheless a testiment to what a strong stiff machine can do.
Funny enough, but I had read that some of the major moves forward in high speed machining, came about by pure accident. A fella missed a decimal place and sent the mill cutter in to the work at ten times what he wanted it to. And it survived. And the finish was better than they had got before. And so, they chucked out what they 'knew' and learned what 'was'.
So very true.
The more you know, the more you know you don't know. And of course, it depends......
When the results don't reflect what you knew, it is also time to ask why. There might be a lot more to it than the simple outcome suggests. Opportunities to learn something entirely new are far and few between.
Also, many an impossible thing has been done by someone who didn't know that it was impossible.....
A now deceased friend of mine had purchased a 12mm capacity Indexwerke screw machine from my Dad to make SS304 taper pins. He set it up and accidentally transposed two of the spindle gears so it ran at 3x the calculated rpm. He found out when the thing wound up and crashed the carbide tooling he had made. He later said to me that it almost completed the cut so he rebuilt the tooling more robustly and from then on produced parts at 3x the speed he quoted the job at. Net result was making $110/hr in the early 1980's.
