DIY mill...

sorry I know but BUMP!

I had to post, just wanted to help some of you were looking for strong lightweight cutting head motors.

Large outrunner motors designed to replace IC. engines in large scale RC aircraft have excellent Power to Weight ratio for examples head to the link provided.

This is my first post hope to be the first of many is there anyone in northants with one built already that would be able to share some machine time.
Thanks to all, Gavin.

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
