Just been given a Raglan lathe with no motor and want to get it running, I have an old washing machine that I can use the motor from but I have'nt a clue how to wire it up, but my main problem is how does the variable drive work as i can't see how the forks guide the v belt pullys on the motor shaft.

Try this user group. There are manuals on this site in the files section.

Thanks John, that is a great help.
By looking at some of the pics on that site I can see how the forks work now .
I,ll have to get the motor out of the old washing machine and see if I can figure out how to mount it up and get it wired with a forward and reverse switch.
I'll keep you posted on the progress, Cheers, Gary.

Hi spooky,
Most washing machine motors are universal (Series.) design and run at quite high speeds (Up to 20000 RPM) so they would need a lot of gearing down. if you have plenty of room you could use the belt and pulley that drove the drum as the first stage of speed reduction. These motors are easy to reverse but they need a speed controller. I have never found a circuit diagram or data on the speed control IC used on the boards I have removed from washing machines. Here is a website with some information on using these motors.
They sell a speed controller using a TDA1085c IC. The data sheet for this can be found on the web and contains enough information to design your own speed controller.
Even though you could use one of these motors I think a normal 1400 RPM induction motor
(Or VFD inverter package and 3 phase motor.) is a better option.
Les.

Unless washing machines in UK are very much different from "our" machines in Australia, the later ones would, I imagine, be using a similar motor system, namely, a motor which is constantly reversing direction, to give the agitator its' forward and reverse action, without the cost of a large and complex gearbox.
"Our" motors have two windings of equal wire diameter and resistance, with a common "neutral" connection, and a capacitor of from 4uF to 10uF value between the active ("top") of each winding.
The "reverse" function is achieved by alternately powering the windings, with clockwise rotation having the "right hand" winding connected direct to "active" and the "left hand" winding powered through the capacitor, then anticlockwise rotation being effected by switching the "active" to the other side of the capacitor, thereby "directly powering " the "left hand" winding.
This type of motor lends itself to very simple control, a single-pole double throw switch is all that is needed, beside the "master on/off" switch, as they don't like being switched directly from forward to reverse.

Hi donhe7,
If spooky is lucky enough to have that type of motor when he removes it from the washing machine I think it would be ideal.
Regards Les.

Sorry about the delay but i've decided to not use the washing machine motor and have been given a mini pillar drill to use the motor from it, though it looks a bit small it may be enough for my needs, it says its a 350 watt on the plate. any thoughts?
