I currently have a Team Cobra Lathe and a stock motor to power it. I was using my ICE to power it, but it kept on stalling under the strees from the cut. I would get halfway into the cut and it would just stop. I need a different power source. I was thinking of using a 4-cell battery pack. Would this work?

That's what I use to power mine, 4 cells.

4cells will work but if you get a motor running machine it works good too
like a much more or yokamo of gfx.

Is there a specific type of cells (3000, 3300, 3700) mah?

wallyedmonds

the cheapest ones you can get coz your gona keep charging them over and over and over.

Are you sure you aren't trying to make your cuts too deep, and that is causing the stall?

I don't know if I'm right or not, but I stop going in the second I see a sign of a cut on the comm. The problem was that my comm was so uneven, so some parts were harder to cut than others, resulting in more stress on the motor causing the ICE to fail.

How many times have you run it? It could be the motor itself. I had a bad brush on an new lathe. It was way too short, looked like someone took off one of the new brushes and replaced it with a used one, it barely had contact with the comm.
Maybe the stock motor can't handle it? Try one of Integy's Lathe motors. They're under $20 each.

Edit: Or it could just be the comm you're cutting.

Just buy a 55t lathe motor so the amp draw won't be so high.

would a 45t work?

Sure, anything is better than a stock motor, regarding amp draw.

try a mod motor and turn the timming down,I use my ice to power my lathe,I turn the ice down to 2.5 volts and it works fine .

Couple of tips if you are not doing so already.

1. Once the arm is spun up use a permanent marker ("sharpie") to cover all the comm with black ink. Makes it easy to see when you have made contact and what bits have not been cut.

2. Line up the cutting bit at the far right of the comm (which will not have been worn by the brushes) and make your first very fine cut from that point. Wind the bit in a tiny amount at a time and make a full cut until all the marker has gone.

I had the same problem trying to run a lathe with a stock motor off my Ice, you dont need a different power source. The problem (as I am sure someone has said) is the stock motor draws too many amps under stress, and that triggers the amp cutoff on the Ice wich I think is 10. Resolution, get a Integy lathe motor 45t will work fine, I have always used 55t, but it is really not much if any differance. With the lathe motor you can run it off the ice at 7.2v and not have a problem. That is the easiest, and probably cheapest solution.

that's what i'll probably do.
