    Sub spindle lathe with soft jaws bored to match in sub spindle. Bit of fiddling with offsets and you should be able to get it pretty darn good.

    Really want a simple trigger spray bottle like the one pictured below. Ive had best luck with these. But they still loose their prime and take 4-5 pumps to get going again. After 3 pumps with no...
  3. Coolant squirt bottle? Is there anything out there that works properly??

    Anybody find a decent coolant squirt bottle? I use them fairly often on drill press and manual lathe. And most of them are junk. Ive tried all sorts from hardware/home stores. Bought 3-4 types from...

    As others said you need a huge pump that turns nice and slow. Hard to find these days. Need to spend a fair bit to get quality pump on a new compressor, or you can look for something old thats in...

    I agree. Theres like a 95% chance if your taking it apart, its completely toast and new grease will do next to nothing.

    Yeah of course. Manually operated makes even more sense but for some reason I didnt think of that.

    This makes sense. So the output contactor should be delayed until after its started? Would this be done with the timer relay used for the start capacitors? Starting caps cut in, and when they drop...

    I have a 35hp RPC. It uses a 150a contactor on the motor, 30a contactor to turn on start capacitors and it has an additional 80a contactor on the output. Its fed with 100a breaker single phase. Been...

    I always wanted one of those light machines mills. They were the ultimate benchtop machine 20 years ago. I settled for a Taig instead and thats what got me into this stuff.

    How is the Lynx 300 compared to your Haas machines? The 300 would be good fit for me, but not much talk of them on here.

    Yeah thats what mine is. The square turret one. Mine spend all its life in a trade school so very little wear. Still makes good parts. I kinda fear the control could die any day though being so old....

    Is this on a T1? I tried most of the other "P" parameters with anything to do with clearance and it didnt seem to help.

    Ended up using the SGL mode and got it to work. If anybody else has any...

    Id look for mid to late 90s. Older machines had really fine pitched inch ballscrews and were slower. Smaller motors. Some older machines had 6 belts vs 2, id stay away from that too.
