    I'll repeat what a few others have already noted- if you don't need it, shed some of your compressor load. If you're regulating the pressure down substantially, reduce your compressor's upper...

    480v VFDs with DC bus access were marketed heavily towards the passenger rail market... why? because 3rd rail power on subway and light rail was between 500 and 800v... so a 480v VFD's DC input was...

    If your current RPC will bring it up with the table-saw running, that means you just need more gusto on the generated leg. I'd take Bill's suggestion one step closer to Neandrethal... get an old...

    The only aside note here, is that the OP is in the UK, so his availablility is not exactly same as ours...

    Hi Tom!

    The SB9 was, and continues to be an extremely popular machine, particularly to the hobbyist/home shop types, because it is robust, well-made, and small enough for two men to carry down...

    That's cool, John!

    One of these days, I gotta get my big L&S moved out of it's storage spot, cleaned up, and powered for work... (sigh) I'd bet there's a picture of it in that catalog...

    That 16 is an excellent haul... why not use it as-is? It's got a backend chuck... perhaps they were using it for chambering work on rifles...

    I'd say... that a better move would be to make a...

    Hee hee... that's penetrating oil.

    Underneath the center of each one of those spots, is a threaded hole, where from beneath, bolts attach the table to it's gimbal base. I cleaned the holes out...

    If you put an RF spectrograph on it, you'll probably see HF noise in the realm of over 600v with regularity. I would not be surprised to see the cord survive it, but once it starts leaking a little...

    I'm not sure how this degraded into a political septic field, but the original poster's question didn't deserve it.

    To test a 480v unit on 240 single, is simple, as many of our simple posts...

    We don't own 'family heirlooms'... they own us... they adopt us, use us, and once we're old and worn out, trade us in for younger generations.

    Greetings, Kakashi-San!

    What you have there, is, from what I've found in my research, referred to as a South Bend model 34, 'Type O' 'screwcutting lathe', non-quick-change.

    If you're killing that many welders in that short a time, you're doing at least more than one thing wrong.

    Yes, first off, they're not industrial-grade machines, second, they're certainly not...

    First off, I'm gonna take an educated guess here... the component that's probably failing first, is your bridge rectifier... and it's probably burning up because it's operating at 24v, but getting...

    If the spindle nose is for thread-on chucks, I would NOT recommend using, or concerning yourself with dynamic braking capacity... as this can easily result in a chuck unthreading from the spindle...

    I'm gonna amalgate both MKSJ and Kris's responses:

    Definitely a 1800rpm motor, and overspeed it to at least 120hz.

    2hp should be more than enough for this spindle.

    The variable drive...

    The proper way to prevent oscillation, is to find the component and geometric circumstance that's causing chatter, and fix it.

    Seems to be a whole lotta complexity here for such a simple problem.

    Karl, this has NOT been my experience.

    My '42 EE used to have the Ward-Leonard DC drive and backgear.

    I've replaced it with an Allis-Chalmers 1800rpm 480v 3ph 7.5hp motor, driving a Gates...
