The speed depends on the material and the diameter. I have turned a piece of 3 inch diameter stainless down to make a ER 32 collet chuck. I don’t take budget cuts. On a recent part I took 0.040 from

That is great news. I have been reading a lot motors troubles on mini lathe. I could be speed the min lathe runs at is the different. Do you due most work on higher motor speed? Dave

I got my Speedway mini lathe in June of 2002 and have used it extensively with no motor problems. I did have to have the control box repaired about three years ago. John [email protected]>

*Question* When running at low speed do you * change your belts * Keep belt the the same and just adjust motor speed * Something else *Second Question* How slow do you typically turn in low speed

I was looking internet on longevity of dc motors and founds you may like read. The first is the most common motors for mini lathes. The second link is on industrial DC motor they very expensive for

Interesting replacement. I do not here of any one changing brushes. I do know the type and size of brushes the use on mini lathe motor will last 1,000 to 3,000 hours. Items like sewing machines and

On my HF mini lathe the controller failed but I had been saving a treadmill motor (110 DC permanent magnet motor with a large flywheel and small diameter poly groove belt pulley) to provide more

Look at improve the longevity of the mini lathe motor. I see a lot members having motors problems. Now is from environmental , operator , motor control board or motor errors? FYI There are two basic

Under some conditions a motor can get starting a lot . The motor under no loal it about 2 times or 3 time running amperage just second. If air compressors is higher but longer too. Most mini lathe

The problems you can run into with mini lathe is more just single speed motor. The mini lathe motor top speed is around 6,000 rpm Now we slow motor down 300 rpm remember the cooling fan is now run at

Don't forget about the difference in expected running times. Starter motors only run for a few seconds under a heavy mechanical load - most common motors run for much longer times under lighter

When modified brushes to fit I did find some harder file that other. Most it was grab bag of different sizes that easy to file than Black and Decker aka Dewalt. I do know some read on subject did say

I had problems with motors in 1970's when hot like is today. The way was resolved was to add more cooling. Either do not use your mini lathe over 90°F or add cooling fans. I even had running water

Just checked at 11:30 the temperature in where mini lathe and it is 104°F [40°C] Hot Not good day to running a mini lathe Dave

This just FYI. My temperature for this month was 79°F thank God for AC My mini lathe is a small shop without AC so have to other things. I only bring up heating because it can have a effect on

The good news this heating of earth has happen before.? Last time was around 1905 it did get very cold in 1944. We have not broken any records from 1905. It is not ever x number of years it has to

Possibly. But my running time may not produce the kind of dangerous heating that we think. I do mostly small stuff. My motor is also a brushless one.? george

Nope. Just a remodeled two car garage without insulation. No ac, just a small fan. Today at my house it was 114. george

It more likely to do with air compressor sitting outside for shop air. The mini lathe should be in a cooler room. Maybe the AC keeping the you mini lathe and you cool Dave

Intermittent operation may actually make the motor internals hotter than continuous running! With intermittent running, the motor's internal fan is stopped while the heat generated internally is still
