    It's time for pencil, paper and multimeter set to "buzz" - check the black wires go where you expect (two to the control transformer, the other three to fuses / breakers in the bottom of the...

    a 10A 240v circuit isn't going to power much - you's be limited to about a 3HP idler, so probably 2HP usable for the biggest 3-phase machine. Is there no way to add a bigger breaker etc. for...

    And loading the shopping into a cab ten feet above ground is a lot more time and effort - I'd take the Datsun too.

    Unless I was ""over-compensating" for something else's size, of course.

    Once you have the converter it's not just lathes, there are mills, TIG welders, grinders bench and surface - the world's your slimy shellfish :)

    If all else fails, strip off the welding winding and add a new winding for the 240v side - this will also give you isolation between 240 and 415, so despite the hassle a Good Thing. I did the...

    Metric requires several gears for the thread dial on a metric leadscrew, because metric works as length per thread (lead) not threads per length (TPI), and I've always found it easiest to leave the...

    The reforming procedure I use isn't desperately difficult, but does require a variable supply of some sort - I use a Variac - and something to limit the current - a proper old-fashioned 100w bulb in...

    Don't be disappointed, that Feeler's a great lathe - just bite the bullet and learn a little about RPCs, buy a few parts (transformer from 110 to 230 x 5kVA, 230v 3-phase motor (about 7HP should be...

    No! Pass as in "I'll pass on that question, naext?" - the Feelers have a good reputation, if it's in good order (certainly looks it) and affordable go for it and put together an RPC to do the same...

    One more thing... once you have 3-phase it opens up a world of used industrial machinery (unless you have superhuman self-discipline) which (at least this side of the pond) tends to be cheaper for...

    Pass on that particular lathe, my mill has three separate motors and I chose to go with a (home brewed) RPC instead of three separate VFDs, had to raise the incoming voltage from 240 to 415 first...

    I dug a bit further into lathes.co.uk, the motor in the Arboga is 1 HP (750 watt) at 400v, that VFD is max 1/2 HP, so wouldn't be big enough anyway - if you hack a 400v or buy a 230-400v be sure it's...
  18. Looking at the lathes.co.uk page on the Arboga,...

    Looking at the lathes.co.uk page on the Arboga, the motor is 400v only (it's a Dahlander-wound 2-speed) and that ABB drive is 230v so you'll lose most of the motor power and torque.

    230 to 400v...

    Bump - nobody's screamed DON'T DO IT! IT'LL KILL YOU! so I'll go ahead with straight mineral oil to get it deep enough to cool the windings.

    UNLESS there's a reason not to?

    Your calculations are right, sensible speed for carbide on small(ish) work. Is the surface you're now getting "torn" looking or more "grooved" (like a really fine thread)? If grooved, the tool nose...

    1.5" x 4 gives half a foot circumference (very roughly), 2400 RPM comes out as 1200 FPM! Come down to 800 RPM and it's close to 400 FPM, I'd be more likely to run (unknown quality) carbide at 300...

    If it's a shorted turn in just one of the windings it can sometimes be detected by applying a low *AC* voltage to each coil in turn, the shorted winding will show a higher current than the other two...
