If you can follow a simple schematic, all well and good....Pricewise, I think it can be done for under £300.....( how much?? :coffee: :coffee: :lol:)

Thanks John, so 1.5 hp motor will do and a 1.5 hp inverter, have i not seen the inverters output quoted as Kw's ?
Ow! how do i measure the motor to get the frame size please? as the Chester book says " not a lot " it is side mounted in the vertical.

Lyn, as I understand it the frame size is the measurement from the bottom/mounting feet to the shaft centre line.
Some info here: http://www.gibbonsgroup.co.uk/blog/2014/06/how-are-electric-motor-frame-sizes-calculated
....OZ.

Doh! my head hurts, just been looking for a motor and inverter thingy with remote the prices don't half vary, the IMO Jaguar cub thingies look to be easiest do you think...Well for a dummy like me any way. I will measure the motor in the morning to get the frame size.. and shaft size to..

Any opinions on who to buy from and what make of kit?
So many to pick from, what about pulleys, do you use the
two v belts or go with timing type belts/pulleys where from.
Q's Q's From what i can see online the spindle pulley would
need to be big, the shaft is tapered and 48mm at the top
and 51mm at the bottom, can't find one that size.

I got my motor from one of the ebay sellers....engineers mate?
Inverter, last one I got was £170 ish from same place I think..... :scratch: Invertek....nice little unit..
I retained the original pulley belt setup on both my Chester mill and more recently on my big lathe.....
The mill has the belts on the third steps I think....I got a standard 4 pole motor(1400 rpm) and just wound the frequency up a bit on the inverter to get me to just over 2000 rpm......
On the lathe, that had a dc brushed motor rated at 1.5kw .....( oh yeah? ) so went with a frame 80 size 2 pole...( cos a 1.5 kw 90 frame was too big and heavy...) 2800 rom....again wind up the hz to get me near the original motor speed ( 4500rpm?)....
In both conversions, I've no regrets at all....the ability to wind the speed up and down is great...
Need any help from me? Just ask....
