Re: Gear reduction for real Bull lathe.
That is my experience, too. In my mind, advancing the timing of the brushes
is not logical, for what is happening inside an electric motor is
essentially happening at the speed of light. Advancing

Re: Gear reduction for real Bull lathe.
That's why I weasel worded what I posted! The controllers are standard commercial units, they're presumably set up to work with any suitably sized motor without damaging either the motor or

Threading Dial Turns and Doesn't Turn
Hello Again,
HF's shows to keep the dial disconnected until you need it. Is that correct to keep it backed off, disengaged while not threading?

Re: Spindle Lopes and Clicks when Rotating
Actually, after I took the back cover off, electronics cover off, rear gears off and lead screw off, just to adjust the belt, all I had left to do was to take out the 3 screws that hold the headstock

Re: Lathe Cutter Starter Set
Part of it is the difficulty most folks have with visualizing 3 dimensional objects. There's a classic puzzle with 3 holes; a circle, a square & a triangle, all with the same major size. Very few

Re: Gear reduction for real Bull lathe.
I've heard time and time again, the motors being set to run in the"main" direction, but never have I seen it documented by the equipment manufacturer. I think it's an old wives tale!

Re: Gear reduction for real Bull lathe.
That may be true on some motors. However, my gear reducer lacks John's
idler, and I have been running my lathe motor in reverse for 3 years now
without any ill effect. My motor, which is a 350 watt

Re: Gear reduction for real Bull lathe.
Some of the controllers are set up to add a speed limiting resistor in reverse. That's supposedly because the brushes are advanced a few degrees to improve efficiency when the motor is running in the

Re: Spindle Lopes and Clicks when Rotating
Taking the headstock off looks like it would be harder than it actually is!

Re: Spindle Lopes and Clicks when Rotating
You need to remove the headstock to access the speed change gearing. On mine, the shift linkage needed some fiddling to get it give full gear engagement in both speeds. Since the shifter works by

Re: Why does the finish look like this?
Thanks to everyone who replied!
The piece is about 2.375"x4" and I was not using the tailstock (I still need to cut down my drill chuck arbor to fit into the tailstock.)

Re: Gear reduction for real Bull lathe.
I don't know this product, but I do know that if the motor has either
lead strapped to ground or common, swapping the red and black wire

Re: turning eccentric
IMO, high speed, VERY shallow cuts. Concentrics expose the cutting tool to alternating shock forces rather than constant pressure and any play in the tool holding/driving mechanisms will show up on
