😊 Thanks for the kind words.

Hey! We are a little late in thanking you for shouting out our channel, but better late than never! You may have noticed we changed our channel from "The Machine Shop" to "Lift Arc Studios" because after finishing our renovations and turning into a custom fab shop, Tay didn't want to be misleading. But again thank you so much for the kind words! I'm the editor of the channel so it truly means a lot to hear nice things about the work we put into our videos. Funny enough we've seen your videos many times before realizing you have known of our existence! As a smaller channel it's extremely validating :) seriously... thank you! - Walker (editor at Lift Arc)

I missed the name change, and was wondering aht had happened to this shop project. I see now that the YT algorythm had offered a couple of your later videos, (the big seat seems familiar), but I hadn't made the connection. Keep plugging away. Your videos are very good, and Tay is videogenic, so your channel will soon take off.

Just found your channel and power watched the whole mini-lathe series. I'm impressed by your dedication to the lathe. I can't wait to see how well it cuts in the end although I fear there's going to be a lot of flex in it.

Sounds like the X axis motor is struggling to keep in step over 750mm PM. It sounded sweet as a nut at 600mm PM so maybe start there and work up. Changing the gears to a 1:1 ratio will increase the overall speed anyway, so let them take up the slack, a distressed motor won't last long no matter what kind it is.

What sort of torque rating does the new motor you put on there have? Was considering playing around with a CNC conversion of my old 7x10 mini lathe now that I have a proper one and working off of your experience would skip a lot of the expensive trial and error.

@RotarySMP

Torque = Power/Angular velocity. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM) In this case it is a 750W 4 pole motor running at 1400RPM So 9.5488x 0.75 / 1400 = 5Ncm. ~ 7OzIn.

Amazing project, you've put so much effort into it! I would suggest, if you can, try find some ground ballscrews to put in it. This machine really deserves them. That backlash is surprisingly high though, somethings going on with the thrust bearings I think.

@RotarySMP

I looked for a ground ballscrew for X, but couldn't find a solution without a complete redesign of the saddle, cross slide and enclosure. The backlash is in the bronze X leadsrew nut, which is 17 years old. Backlash is less critical on a lathe than a mill, as you do not normally have load reversals in a cut. Thanks for watching.

@@T.Ackland I used the Mini lathe for 5 years in it's first CNC conversion. I got pretty familiar with it's limitations.There is a clip on one of my videos, which I grip the headstock and tailstock and twist them, with a clock measuring deflection. If you compare the bed cross section (poorly ribbed thin parallel Tee sections) to a real watch lathe of similar capacity, like a Boley 1a or schaublin 70, that is what I mean by a wet noodle. Yes with sharp highly positive tools, and light cuts you can get jobs done, but it is pretty painful and chattery, as diameters increase, but the lower RPM is high, with limited torque. I wouldnt return it to manual, as the manual drive components have been binned. They were also no a great design, as witnessed by all the required mods. I have monetised my channel, but it doesn't cover the hobby costs.

It is definitely a time machine. I started it at the start of the year expecting to be finished by about March. Where did the time go??? Thanks for watching.

To be honest, I wouldn't dream of running a CNC machine anywhere NEAR a region I can hear mechanical distress of the motors following commands. Like, nowhere within 20%, instead of hunting how close I can get. Regardless whether an impromptu check can detect lost steps or not - the potential for gray hair down the line is just far to high. As far as I'm concerned, it's just the price one pays for running an open-loop rig. You want to be 1000% sure the machine can actually do what you tell it to do, not keep wondering what exactly went wrong this time.
