So I've flattened the back of an old Marples chisel (by crikey it's hard steel). I did the grunt work on the motorised jig, and the good news is that the only dubbing was at the cutting edge, which has to be ground back anyway. Finished off polishing manually.
Have almost put a flat bevel on it (atrocious condition before - sloped, bent, angled, convex, you name it). I have to say that this flat bevelling is a mug's game, and can't wait to get my grinder (in the next week with a bit of luck).

This device 2000W 220V SCR Electronic Voltage Regulator Module Speed Control Controller HP | eBay will give you variable speed for any universal motor tools. Just put it into a box with a single powerpoint aon one side and powercable on the other end. I made two of them and use them all the time. Router, vacuum cleaner, hot air gun, drills... just don't overload it or the blue smoke escapes.
Cheers,
Joe

I wouldn't think any lathes would have a universal motor, nor DPs. Easy way to tell Universal from induction motors - Uni's are screamers and inductions are quiet rumblers. Inductions are big heavy suckers and so are usually (probably exclusively) in stationary machinery.

Yup, that's why I have a Universal motor 750w 65Nm power drill mounted in a stand (apart from also getting up to 500mm travel with the particular set up). NCArcher et al can wax lyrical about motors, but a 3 phase induction motor with a VFD will give you variable speeds (but pulley changes are required for more torque). A DC motor is kinda halfway between a Universal & Induction in that it's reasonably quiet, variable speeds. There's another system that I know little about with some kind of sliding (?) belt variation (as used on the Jet JDP 2800 Drill Press) - Tony?

Halfway down the page of this article is a gif file that shows how it works.
One of the pulleys is spring loaded to be at it's smalles diameter, to keep the belt tight, the other one is moved towards and away from the first one to vary its diameter. They work very well (I used to have one on my lathe for a few years, until it wore out - pulleys made from bakelite) and take very little maintenance.
That may be the cheapest way to do it - if you can find a pair of those pulleys, Dave.Cheers,
Joe

The spring loaded pulleys are quite common on wood lathes. This is the Carbatec version but I think others (Hare and Forbes) also have them. Variable speed is operated by the lever on the front of the motor.

There are some other powered flattening ideas here: Back flattening - horse power rather than hand power

Great ideas! Oh the agony of manually removing that last 1/4 of a mm of dip on the corner of a chisel
