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!

Re: Making a New, Elliptical Compound Thrust Plate/Large Dial Upgrade
Operation has been fixed, by installing a thrust bearing and a ball bearing, inboard and outboard of the thrust plate and a sleeve for the graduated dial to ride on.? The sleeve corrects the tendancy of the dial to cant and bind the rotation and provides something for the hex nut to clamp against as preload.? Compound is snug and smooth, the only thing to deal with now is the backlash, some other time.?

Making a New, Elliptical Compound Thrust Plate/Large Dial Upgrade
Making an Elliptical New Compound Thrust Plate/Large Dial Upgrade
?
I'm installing larger dials both the cross slide and compound on a Craftsman 6" MK2 lathe and had the need to make a new thrust plate for the compound because the original is cast and the boss were the dial base needs to mount is tapered due the the draft. The thrust plate is elliptical and I wasn't sure how I was going to do until popped up.? I grasped the concept quickly and did not actually watch the video through the machining process.? Had I done so, I might have been dissuaded as it looked too complicated.?
Joe’s method shifts a vise with the workpiece around on the rotary table by predetermined increments.? Not being aware of this, I went a much different way, but I like how I did it.? I plotted out pin positions ?for milling the two radii using on a backing plate mounted on the rotary table. Means breaking the setup down and repostioning the part for each radius.? I also first used the mounting plate to turn the boss on the lathe.
Start of the project, with the rotary table mount plate and the thrust plate stock pinned to it for turning the boss. Originals are on the left, new dial on the right.
?Turned boss.
Second major radius milled takes rotating the part on the locating pins.
Milling the end radius meant shifting the workpiece on the mounting plate to the second set of pins.? For my part, rotary table rotation was 48? on each side.? Any further would have dug into the primary radii.?
Finishing the thrust plate took drilling and counterboring holes for the mounting screws and filing out the machining marks.? Due to the large dial backing ring, the mounting screws had to be flush or nearly flush with the surface.? This required turning reducing the size of the SHCSs, but I like the look.?
Finished part, original and dial parts ready to install.
New thrust plate installed.
New dial installed. Original thrust plate in the background.
?
There is a problem here, however.? It doesn’t work smoothly and will require some remedial work.? The new dial cants when the set screw is locked.? I think because the set screw is off-center and it clamps on the transition between solid shaft and the start of threads on the end for the handle/nuts.?
?
More on this to come.

looking for the original, on the floor with the flashlight, like
the CSI guys.? Voila!
Getting it back on the spindle was a task.? Both the key and ball
liked to escape and hide.
All back together, with some improvement.? It doesn't slip out in
the second highest speed now, but does still at the highest.? I'll
try it with one of the new springs when the order from eBay
arrives.? I've located on spring on McM-C that is close the
original spring (1/8" OD, 3/8" length, 0.021" wire dia.) but is
longer (1") so I can trim to some lengths greater than the stock
spring.

Re: Drive Coupler Not Staying Engaged, Craftsman 101.21200 MK2
Overhauling machine tools can be a big part of the fun, or it can be
a real drag.? I've done a few also.? I bought a couple of the asian
"mini-" machines new, but the newest since then is my 1986 Select
knee mill. It was well enough used but did not require any remedial
work.? The one that took the most work was a pre-WWII Rivett 1020,
two years of extensive repairs, remanufacturing of parts and even
some castings/machining, but it was worth it.? When I moved 7 yrs
ago, it got toppled on its face, so did not make the move.? While it
was getting repaired, I came into a 1946 motor generator Monarch
10EE with a Newall DRO that had recently been fully restored, so all
I had to do was get it here and set up.? I have and have had DROs on
mills but never a lathe.? Pretty sweet.?

Re: And now.......reversible
David, how are you seeing "The motor wires connect to both the 3-6 pair and the 1-4 pair, but with reversed polarity on the 1-4 pair."?
You are correct in that that would work but the diagram does not show it.
Ralph

The motor wires connect to both the 3-6 pair and the 1-4 pair, but with reversed polarity on the 1-4 pair.? This of course only works on DC motors that reverse with reversed polarity.
Note that it would work the same if the motor were connected to the 2-5 pair and the battery to the 3-6 and 1-4 pairs.
