Note that the potentiometer is operated at low volts BUT the electronics may now be isolated from line power, intended to be enclosed and therefore from us. Always take care in this regard, never

Looks great You till you work in wood. Dave

Yes ads pay for site. Some where I had details on cutting a variable pitch thread. The used a South Bend Lathe 9A for camera lens. Hopping that makes to YouTube. You may fine up to 4 TPI [ 6mm]. Most

Yes, far too many of them.? I think I was a little overly proud of the project.? :-) https://projects.foxharp.net/bandsaw/ paul

Hi Lone tree. I cut my thread with a normal bit. The item was an adaptor to join additional lenses to a Canon G2 digital camera. It was an internal thread, 40mm dia, 0.75mm pitch, both ends ! Worked

Don' think that will be cut with a normal threading bit.? ?(Yes, I endured the insufferable youtube ad to see this)? ?8^) -- Lone Tree, Colorado? ?USA

I haven't tried using a treadmill motor controller and cannot be specific but hope this is of some help. Lets start with some calculations from your motor DC specs: Power = 120 volt x 21 A = 2,520

I was thinking something like that, or a powered tailstock. The treadmill include motors look exactly the same as those seat ones, just a bit beefier. Tony Sent: Thursday, 8 February 2024 9:51 AM To:

I used a stepper motor to drive the X axis on my mini mill. It actually works great *Have A Great Day * *Tracy Ranson*

The Jan/Feb 2024 Home Shop Machinist has a cover article about making a power X axis drive for a mini-mill table that uses a 12V car seat motor (American Science and Surplus has been selling them

Most of the ones you’ll find will have a 100v-ish DC brushed motor rated for about 0.5 – 1HP, which is as good as or better than what our 7x12 lathe have, especially the older ones. Very similar

Any photos you post of ban saw? Dave

Mike -- good guess -- my bandsaw is using an MC-60 controller.? The pot was connected directly. Thanks for the info on the MC-2100, and on the youtube stuff.? I'll take a look. Tracy -- do you

I see why Treadmill motors are popular. On trash day you go down the street and pickup for free Treadmills. All you need to do is remove a new motor. Dave

Paul I have a couple treadmill driver boards that I used to drive a treadmill motor on my mini lathe if you’re interested *Have A Great Day * *Tracy Ranson*

Paul I forgot to mention if ya do facebook there's a group all about treadmill motors on Shopsmith's , Some guys that have done a lot of homework & shared it .

So I'm guessin that you probably have a MC-40 up to a MC-60 motor control board ? These aren't the best TM controller to use , though folks like then because all ya need is a pot to make them work .

Thanks WAM, possibly the foot speed control I swapped out with a 20k pot was a photocell and vane not the hall effect and magnet. I did not do anything with the pot other than mounting it on my lathe

Motor is a popular discussion subject for us lathe owners, and many solutions have been precented. However, (maybe I am blind and have memory losses) , I can not see any stepper motor. The price is
