Well, it depends if you have, or can borrow, a tap to match the spindle thread. I do (maybe "did"?) have one for 1"-8tpi, but not for...

Think about it..... If they fit the jaws decently, they cannot move radially on one jaw, without moving sideways on the others. So the most they can move...

If you develop the habit of spinning the spindle over by hand a turn after completing the setup of whatever it is you are working on, the chances of causing...

He does not have much choice of pulleys. The machine (the RandA) is a flat belt machine, where the spindle pulley set has been modified to have just...

RPW: Agreed, within limits.

The original topic/questions appears to have been thoroughly dealt with. You know how this place goes, so...

A consistent error is generally due to either:

1) not being adjusted correctly

2) having something on one of the anvils (debris,...

It most certainly would be with back gear. I'd go as low as 30 rpm, although with a 6" (diameter) lathe, 50 is fairly equivalent to 30 with a 10"....

"Honesty here as Doozer is using the word, means "Doozer thinks it ... Doozer says it" (or writes it). It's not "honesty" in...

2 pole just needs more speed reduction.

BUT..... If you try to do the speed reduction by VFD, you lose more power getting to a given RPM...

Ja.... But that makes no difference, really. If the ends are good, the middle part is set, good or bad, it's as it will be. You have to "find"...

a 6" lathe is good with a 4" chuck. Maybe better with a slightly smaller chuck, but any smaller than 4" gets into either crap, or a large...

There are plenty of ways to hold the part to machine it.

The tricky bit is arranging the cuts so that they agree at both ends. With so...

Neighbors keep chickens here. Nice friendly sound, but they do fuss when it's food time....

I looked it up. Same model number, 3 phase.

JR:

You are fine by me.... Got no problem with you. Never have.

I am well aware that if I happen not to like some post, or...

A motor HAS TO slow if it gets any extra load. That is how it allows more power to come into it (more current). The question is how much it slows....

[J Tiers]

And that is just a "nominal limit". The actual speed at which torque decreases is not set in stone by state law, it depends on the motor. Many...

1) Sure, HP is "potential", and is only provided if the machine demands it. BUT, how does that happen?

It happens automaticall...

Yep, I have a 5.25" Logan (that's 10" for the "murricans") which is running on a 1/3 HP 3 phase motor that is a limited duty cycle...

That's what I figured..... the save is always satisfying, although I always find my F^ to be extremely annoying , save or no....
