DIY mill...

Hi Gavin
Yes these motors must have some chuff, I use front loading washing machine motors for machine tools. You can get constant speed from 500---12000RPM. www.calenterprises.co.uk/speed.html I am planning a mill come surface grinder using 60mm pipe for the column, a heavy cast iron block for the table and other bits made from machined cast iron held together with metric screws. Will post some pics when I can be bothered. I only need to flatten stuff out and cut the occasional slot.

Best regards Keith

Hi Keith
Do you have experience with those motors??? Any good? I plan to replace my CNC Mill induction motor with washing machine one + controller. Spindle speed variation it is something my CNC machine does need :)

Hi Gavin
The motors are really good, not enclosed but you can soon make a tinplate caseing. One thing you and I will have to watch when using it for a mill will be the flat belt which normally runs vertically on the washer. I sold a controller to a guy who was fed up of snapping belts on a pillar drill. He put a V belt pulley on the motor shaft. The 12000 RPM is a bit overkill so more pulleys may be necessary but some mills have gearing and use 3000 RPM induction motors. I used the original washing machine pulleys on my lathe.
I am looking forward to strapping this ironwork together and getting a mill/grinder going.

Cheers Keith
