Bruce, I have several as well as a couple of recycled electric lawn mower motors. The mower motors are rated at 1.1 HP and 4000 RPM. As an experiment I set one up with a light dimmer switch and it ran fine unloaded as a demo! I would however use a motor controller in a real world application. ? Could you give a quick rundown on removing the motor and controller from a treadmill? ? And how do you identify the motor controller from the rest of the p c board? ? Bill in Boulder CO ?

Hi group ? Some days ago I complain and asked for advice and help about my LMS 5200 lathe BLDC motor. It would not start automatically, it needed a manual twist and it made a terrible noise. The FAULT lamp was also lightning. ? I had some time ?(one year?) had a problem with unstable rotor , so I open it and found a (ugly) worn axel under the bearing, but it run. I got many feedbacks now, so I decided to remove again the motor from the electronic box to make a new inside look. Then a found the big white connector from motor to PCB was not in correctly position. I just press it in correct position and motor run perfect (with a little bit unstable rotation) ? So this is a free advice ( from a man that should know better): Check the connectors! Specially when you open the electronic box . ? Many thanks to WAM that send a lot of links about how a BLDC motor works. This is one:

Re: Mini Lathe - Mini Mill
The fignoggle?split delrin nuts do take out most of the backlash. What is left is the play in the x axis bearings, and the y steel on steel. Some of that can be taken out with the handwheel nut adjustment. You can get it down to just a couple of thousands, but I can't get it all out. I've made a lot of stuff on the mill and the little bit of backlash hasn't been a problem. I would probably switch it over from the metric screw to the SAE screw if it came with the adjustable split nuts.?
I've heard of people making plastic?nuts from thermoplastic and I know of one person who did make?some.? You could machine or print them.? In either case, the threads are made undersize then? you clamp them over a heated metal screw, and the plastic flows.? ? The application where this was used was not a lathe but a tracking camera mount that moved a good size camera and its attached optics.? ? ??
The next step up in quality is ball screws.? ? I have some.? I bought the cheapest I could find on Amazon.? I tried to figure out how to measure backlash and periodic error and gave up.? You need something?better than?a dial indicator?to measure it.? ?If your measurement tool only good to 0.0005", then the cheapest?grade of Chinese ball screw is "mechanically perfect".

Re: X axis DRO, my next project
Chris, let me express my admiration for your solution to your lathe travel measurement question. Cheap, simple, reliable; what’s not to love! I am going to put that at the head of my “Projects To Do list”! ? On another note I frequently read questions from the newbies asking for sources of information on basic lathe operations. I do not think that many are exposed to this sort of education in high school. That is a shame for as we all know this is a very entertaining hobby! But do not despair for there is an outstanding series of books covering all aspects of machine tools. I refer to the books written by Fred H. Colvin and various coauthors through the first half of the 20th century. I have found them both s original editions and as Lindsay reprints at very reasonable prices. I recommend “Running an Engine Lathe” as a good starting point. ? These books have been very useful to me in my hobby and sometime business!??? Bill in Boulder CO ? Sent from for Windows 10 ?

Thanks Chris. I couldn't come up with why I'd care if the DRO had an absolute feature or not.?
The DRO I have on my tailstock is a 12 dollar caliper I cut up and that really makes drilling, counter boring, etc to a specific depth a breeze. That's what really got me to thinking about the Z axis DRO. For that though I do think I want it to cover the full length of travel but a short one with magnetic mounts on the front from a caliper could work for a while.?
I don't have a mill or 3d printer so making mounting brackets is a vice and file job here LOL.?

Re: X axis DRO, my next project
On Wed, Mar 23, 2022 at 01:50 AM, Ryan H wrote:
For my next lathe project I'm thinking about adding an X axis DRO.? It's really the one axis there's no built in measurement for and I think I'd really like it for boring to a specific depth and tasks like that.? I'm currently looking at the Shars stainless 24" units as I have a x14.
?
If anyone has tried these, how do they deal with all the electrical "noise" from the lathe?? I have three 6" Mitutoyo digital calipers and two sets absolutely freak out within three or four feet of the lathe if it is running.? The other set is okay and my 4" Vinca are good.? I'm concerned the Shars DRO won't deal with the noise either so any experience with the Shars or any brand, good or bad would be appreciated.? Thanks!
?
I put an Igaging acuremote on the Z axis of my 7x12.? Based on my past experience with electrical-noise problems I went with the stainless steel scale, but to completely eliminate the noise problem I still had to open up the sensor box (the one that slides on the scale) and solder a 1 microfarad capacitor between Vcc and Gnd.? I think that's because the batteries are installed in the display box so electrical noise gets into the power supply & ground lines on the connector cable. It is _very_ nice when it comes to doing things like boring pockets to a specific depth, or (if you have a toolpost-mounted drill chuck) you also can drill holes to a specific depth.? I originally added the DRO for an odd kind of ball-turner I bought from LMS.? The ball turner installs in place of the compound, which made it difficult to advance the ball turner into the work with any kind of accuracy.? As part of making it work in a reasonable fashion, I also attached a handwheel to the leadscrew.? I engage the half nuts and use the handwheel to advance the ball turner into the work.? In addition, the combination of DRO and handwheel on the lead screw is very useful because I usually have my plinth installed instead of the compound -- the plinth is much more rigid, and the DRO provides the measurements I need on the Z axis. If I'm threading or cutting under power I remove the handwheel handle so it doesn't smack something (like a hand).? You can get fancy with a foldable handle or a castle nut type of drive if you want, but I just went with the KISS principle. Mark
