Posted by pgk pgk on 15/11/2014 07:47:04:But to put it in practical terms: If one finds, say an M300 for £2K, then how extra much for shifting it and converting it to single phase (and some pocket money for extra muscle this end – it's not going to be a one-man job).
what are the practical snags of a larger lathe?

Toughy, you could pull a fast one and run 240v single ph to 220v 3ph then have the hassle of rewiring the 'needed, controls. That s assuming the motors dual voltage, mine isn't.
Otherwise plug and play from a 240v 1ph source now looking at £1300 for a 7.5kw inverter or same price for a noisy rotary convertor.
Lifting and manouvering is a one man job. There is a tapped hole in front of spindle that you can screw in an eye bolt £3. Just pick it up with tractor. I use a 5ft crow bar to nudge across concrete floor purely because no room for a 6ft.
Paid £850, sold Dickson toolpost £110 so cost £740. Trailer hire think was £36 and £3 for an eye bolt. Inverter £900 ex demo 3 1/2 years ago after a smaller 4kw £650 failing within 1 1/2hrs. Chucks and tooling £1000 should get you going, don't buy cheap chinese its wasted money.
Downsides, if clothing catches you wont stop the machine. Chucks can be heavy certainly the 8", 6" Elliott no problem, one hand job with 5 1/4" easy with the D1-4 fitting.
Serious positive is there are no change wheels to faff about with, something the Chinese haven't cottoned on to yet in near on 50 years. By that same with newer flat top Colchesters just dial in thread pitch whether metric or imperial think its up to 3.5mm pitch. I swore blind last Harrison scrapped 4 yrs ago I would never ever have another change wheel lathe again.
Why not have a small Chinese and something along the lines of a Harrison M300.
