Think you will have more luck looking for maxon rather than moxon. they have a web site but cant spot one you've got easily. Maybe a photo would help.

That size I'd lay odds on it being 12V, unless its for a special application, like aviation use.

Draw two circles on a piece of card, equal to the diameter of the sprockets plus half an inch.( if the sprockets were say 2" and 4 " then the circles need to be 2 1/2 and 4 1/2&quot the circle distances need to be say 1" greater than the centre distance….( if that distance is 7" then the distance between the centres is 8&quot. Now draw lines from the circumference to join each circle so you end up with a sort of uneven oval shape….Add a flange about an 1" wide….theres your cover..in card…transfer to sheet metal. Cut out and weld up or use your favourite method of joining metals…

Easier to make than describe…but I'm sure someone will have a more eloquent way of describing how to….

You are still going to need a fair size reduction on your chain / timing belt drive.I would dare say that when you are winding the handle for the down feed on your mill you are only turning at 30-40 rpm so you are going to need a 10-12:1 reduction.I would fear that relying on your speed controller to reduce the speed to that level will leave you with no torque .

I’ve used parvalux motors with 24v motors at 3 amp and 30rpm and they are only just powerful enough to lift the head on a wm 18 mill

You dont say what your small mill is or how much torque is needed to drive the vertical axis, also without knowledge of the motor specification you dont know whether it will do the task, and very importantly how long for.

Maxon make a wide range of high quality motors some with precious metal brushes, ironless rotors and other features to enhance performance for specific applications. I am not conversant with Maxon's part numbering but if you go to a lot of work to use this motor and gearbox and it fails after a short time, a replacement motor will be expensive. It would definitely be best to do some investigation and experiments before you go to far.

For you to consider this application in the first place I presume the gearbox has a substantial output shaft?

"the circle distances need to be say 1" greater than the centre distance….( if that distance is 7" then the distance between the centres is 8"

Why the increase in centres John (Rudd)?
