I think the chester mill is the same as the X1 mill. If I'm correct arc euro do spares.

are you sure it is the motor – usual failures are the controller boards especially if it is a somewhat older model as those electronics were more prone to fail than more recent models – replace the motor with an old 100W lamp and see if the controller will alter the brilliance.

Hi

Thanks for suggestions – he has replaced the motor with various sewing machine motors that quickly burn out (may that be the controller board?) – he asked me about a lathe motor he has been impressed with that has lasted him for years a Parvalux PM11 517495/3D and is thinking of putting on his Micro Mill – my Dads 81 and quite ingenious so is comfortable adapting the machines to fit his needs. He makes model ships/miniature furniture and other miniatures that take his fancy.

A low cost solution is a 12v DC scooter motor with a PWM speed controller. This seems to be an increasingly popular setup being used on small model makers lathes such as the Unimat. Motor and controller can be had off ebay for about £30. I don't know how much torque they have but I'm guessing it would be at least equil or better than a sewing machine motor. Hope that helps.

Could you provide a link to something you think might work? Thanks

Sure, something like this 24v motor and PWM should be OK. I'm no expert though so might be better waiting for a reply from one of the electronics guys.

It might be worth going for a higher voltage to reduce the current, 120 Watt 24 Volt motors have been recommended on the Unimat Group, and there are plenty of 24V switch mode power supplies about now. I don't know the dimensions of the mill, and a lot of the listings on eBay don't give dimensions, but this 2400 RPM 150W motor looks pretty typical and is 68mm diameter and 108mm long if that is any help.

Edit: Don't bother looking, it is the same one Hollowpoint suggested

Silly question, but do these need a transformer or plug straight in from mains power?

The one I linked to would require a Transformer or 24v power source. But you can get them that reduce the voltage.
