A live center turns with the work. A dead center is in the tailstock. A turning center turns with the work and is mounted in the tailstock. David Lee ... ...
Hi ... Precisely, though perhaps a misnomer, a live centre is (can be) mounted in the tailstock. A live centre in the headstock though turning with the work is...

It's pretty fundamental, David Halfpenny, that the headstock center would be non-hardened because it turns with the work. No need to go to the trouble and...
While I do have a live center for my spindle I rarely use it, I have one made from a piece of 1" bar with a shoulder on it which I mount in the 3 jaw chuck and...

Hey, all. I was trying to part off a small piece today, and my lathe kept turning itself of when I started to cut with the parting tool. I looked at the...

Did it work once you let everything cool off? I don't think the motor has a thermal overload. I just took mine off yesterday my wiring is the same colors as...
There seems to be some connection between the motor and the circuit breaker trip mechanism. Try this out on your lathe: Power it on, and lightly depress the...
One answer to that is you're using a very slow seed for reasonably thick stock if it's steel. The slow speed causes high amp draw and the motor heats up. If ...
Really? This is not variable speed. This is a 500W motor that always spins at 1700 RPM. When you slow the motor down with a high load or stall or near-stall...
But the motor always runs at the same speed. The speeds are controlled by belts and pulleys in between the spindle and the motor shaft. This reduces the...
Okay. Here is what I have for wiring. The motor has four wires: Blue, Black, White and Red. Black and Red are the plain winding, White and Blue are the...

Two options, leverage or a dead blow hammer, in that order of preference. You will need to block the spindle from rotating some how. Cheers, Thomas. PS. You...

Cutting speed with a cutoff tool in a lathe, cannot be properly measured in RPM, except at one depth of cut. Feet per minute would be a better speed...
Right, which is why I did the conversion from fpm to rpm. I realize that the cutting speed will decrease as I get deeper into the stock. One of these days, I...
Thanks, Gene. I may know electronics/robotics, but I do need a bit of help in the machining department! I was doing just fine this morning after the...
