Hi Oz , from what I have seen of Harrisons don't take anything for granted without seeing it with your own eyes, like your motor, what the manual says it will be and what it ended up having can be two different things with Harrison lol.
I think John is going to run his off the rotary phase converter, I am not sure about this but I have heard somewhere that you need a special inverter to run a twin speed motor like John's 140 has fitted.
Each speed on the gearbox has the normal speed as marked in the low range when the motor is running in low ( electrical ) speed 1500rpm range , then if you switch the motor to high speed range 3000rpm each gear selection would have the relevant double speed of the low motor range. So in effect twice as many gears.
Not sure if it needing to be special inverter is correct or not ...........anyone else know ??
Cheers Mick

Hi Mick, you don't need to convince me that Harrisons made in that era were devoid of any predictable logic and completely random in deciding specs of their machines.
They're often a bloody nightmare to source the right parts for because of these assembly inconsistencies.
I did wonder whether a normal inverter would cater for the 2 speed motor or a special unit was required.
On the subject of John's 140,what I did notice was the backlates etc in photos seem to be the L00 taper fitting which is a huge improvement over the threaded spindle like mine and micktoon's.
And John, you look ever so youthful and very fetching with the blonde wig on. :lol: :lol:.....OZ.

:poke: Oh Oh whats to become of John & Mick will it be a case of :hammer: fighting for bargains when out at Car boot sales for the Harrisons parts or will they :med: over a :beer: a share the spoils.
With spring coming on over there and the car boot sales starting soon John will have a wish list as long as his arms

Hi Oz , I thought you would know about the curse of working out what is what with harrisons. Well spotted John's lathe is L00 taper nose , it is better but you can not really make backplates etc , well not as easy anyway :bugeye:, lucky for John he has everything except I think there should be a 16 inch faceplate too.
Hi Ginger nut, Yes we are looking forward to the car boot season starting again, we normally share the spoils anyway and we both have most lathe related stuff anyway now, we both think 2015 is the year we will come across 'The Mutha Load' ............... You know the one where the old guy is packing in and has his whole collection of engineering tooling for sale :drool: :drool: :drool: ............................. Dream on eh :lol: Who knows what goodies we will uncover :thumbup:
Cheers Mick.
