Thanks for the reply. I guess I didn't think about chatter since I
can deal with that with a VFD controlling rpm. The metric thread
cutting makes sense although I have just used a die holder. I was
thinking about making a transposing gear, but I have not needed one
yet. I guess this is further evidence that there are 10 ways to do
the same thing in machining.

An electronic lead screw allows you to cut any
pitch thread you want, SAE or metric. It will also allow you to
use any feed rate you want. So, if you are developing some
chatter and want to reduce your feed from (and I'm making up
numbers here) 0.010"/rev but the next change gear down takes you
all the way down to 0.005"/rev, the ELS will allow you to pick
anything in between (on the fly) till the chatter goes away.?
Basically it gives you almost infinite?control of your
feeds.

No offense intended here. I must be ignorant on the
subject. Enlighten me on what I could do with an ELS that I
could not do with a QCGB or a change gear set. I understand
that change gears are a pain, which is why I bought a lathe
with a QCGB to replace my change gear lathe. The price of
the QCGB lathe was offset by selling the change gear lathe.
If it is about not using change gears, it seems that a QCGB
lathe would be cheaper than an ELS upgrade.
You have to understand that I am still trying to figure out
why I would want to buy a water heater with Wi-Fi so that I
can communicate with it via a phone app. All I want from a
water heater is hot water when I turn on the tap. My QCGB
lathe has 40 feed speeds. I think I have used about 5 or 6
of them in 3 years. Infinite control of the feed speed seems
utterly useless to me.

Rui, my Craftsman 12x36 has a direct
drive motorized Z axis. Not sure what you mean by
"all the electronics"?
Eventually I might get around to doing a
motorized X axis.
The hardest part is deciding how you are
going to motorize the axis, and implementing
your decision.
It took me years after following all of the
discussions?on the web to actually?doing it.
Let me know any questions you might have or
if you just want encouragement.?
I did it all by myself without anyone to talk
to, that made it tough.
Until I got to the programming part where I
got some great help.
Once you get the motor mounted I have a great
stand alone program for motorizing an axis.
Hello
all! Has anyone done an electronic lead screw
conversion on their atlas lathes?
If so can you show some pics of the project. I’m
looking to add one but seam a bit complicated
with all the electronics.
Thank you!
