I live in Finland and so swedish sandstone (some of the best natural sandstone come from sweden) grinders are quite common here. I've always wanted a tormek style grinder but I found the actual Tormeks to be too expensive and also on the smallish side for my taste, but I found this old grinder for 50 euros, here it is after I dragged it home

Multiple pulley reductions give a nice slow speed without being bulky

My first job was to fit castors to the machine so I can move it about easily.

I wanted a tormek style grinder and that means a rest I can attach jigs to, I used 19mm pipe and a 3/4" threaded rod I had left over, so a bit bigger than the tormek rest which is built from 12mm rod.

After painting and reassembly:

Then I trued the stone using a diamond T style tool meant for bench grinders, I also added another lock-screw to the rest, just one lock-screw wasn't solid enough. it's just a temporary screw there for now, will make something better looking later.

Then I made some jigs, a real simple one for chisels

I still plan on making some jigs for knives and scissors. I have ground a few things without the jigs so far and it leaves a suitable ground finish that I can then hone on oil stones or diamond plates, don't need a lot of work to achieve razor sharpness. I am quite satisfied with this homemade "tormek".
 
Nice work. Much more refined than the one my grandparents had at the farm. You had to pedal it!
 
Sharpened my axe last night. The sandstone on this grinder is probably finer than I thought, took a very long time to get rid of all the material so I could grind a new bevel on the axe. And I am still going to have todo it again because I got the wrong angle for a woodworking axe. After honing it I got it shave sharp though, then I decided to give it a few more strokes, slipped with the hone and today my left hand is bandaged.
