Ok, I know very little about using a lathe, I have two a Mini 4x12 and a Craftsman 12x36 but I have had the time to actually use them. I have done some turning and parting but haven't actually made

John Dammeyer's original ELS accepted one pulse per rev and still does accurate threads and turnings. Ralph

Do you have a gear ratio between motor and spindle? Do you have high and low gear?? If you do the motor option is a No-No. The encoder counts are entered as a constant in the software so could be

Hi, Ralph, Is it possible?? Yes.? Is it worth your time?? The encoder I used cost around $15, so I would vote "no" if it was me, but to each his own.? Putting it on the motor shaft could be

I used DC gear motors for power feeds on a few of my machines, including a worm drive car windshield wiper motor for the X axis on my Atlas mill, which is maybe half or two-thirds the size of your

Thanks Charlie, that is what I was guessing. I am "thinking" of using a optical disk I could pretty easily do 100 holes doing more would get tedious, and I am "thinking" of putting the encoder on the

Yes the Consew motor drives the spindle. I do not want/need full CNC just motorized lead screws with automation. Other retros I have seen had the Y motor below the table with a pulley, that is why I

I have seen some people used electric drills, so I am confused on how big of a motor is needed. It would not take a big motor to move the table, except for Z that might take a bigger motor. But it

The consew motor is on the head not the X axis. ?? Any chance of photos of your machine, this would help I am sure to see what you actually have. Thanks -- John

RAlph. Very nice machine thanks for sharing. IMHO this machine would not be a good candidate for CNC retrofit because of the following reasons. The X axis is not much of an issue, stepper connected

Hi, Ralph, The spindle encoder is crucial so the ELS controller "knows" how fast to drive the lead screw at any given instant.? I usually thread now using a hand crank; the change gears ensure that

Thanks that is why I asked! I do not want to turn dials. I do not need CNC, well at this point I do not need CNC. I just want motorized X, Y and Z. The Clausing 8520 Vertical Knee

Thanks Charlie, that would be helpful! Now if I can just remember ... Ralph

Charlie, and others. Why the spindle encoder? Is a multicount required to get the spindle speed? I have seen lots of RPM devices that used one pulse others got their accuracy with 8 pulses. So is

Eddie All good information. Thanks.for sharing, I have a lot to learn and experiment.

Those are for the X axis feed on a mill. IMHO far too big for the Clausing 8520. What do you want them for? You said X Y Z which indicates CNC. If so these are totally wrong, as are the geared motors

Hi Ralph. I am unfamiliar with the Clausing mill. Any chance of a few photos.?. Can you remind us all the of your final game plan, thinking it is it to provide power feed to the 3 axis. I cannot

Should I use these type of motors ( https://www.banggood.com/0-200-RPM-Power-Feed-X-Axis-150-Lbs-Torque-for-Bridgeport-Milling-Machine-p-1281067.html?rmmds=myorder&ID=48036&cur_warehouse=CN ) for my

Hi John! I bought a couple of packages of 12"x12" mirror tiles and I was using those but it makes it hard to get a good picture from my camera with all the reflections. I sandblasted one of them a
