After a fifteen year gap. I’ve come back to serious woodwrking. For many years made a living by it and loved it, but started to lose money and had to jack it in. nOW MY PRINCIPAL EARNER IS WRITING ( NO OVERHEADS!) And a total lack of control on the caps lock key.
But anyway, to get back to the point. Among thre few things I saved from the dying ww business was an Elu bench grinder. Which died today, shuffling off its mortal coil – or for the technically proficient, mortal capacitor. Though heartbroken, I was pleased as this thing could draw the temper from a chisel at three inches distant.So, after a long session of self-deception I squandered several hundred pounds o my children’s inheritance on the top Tormek.
So, coming to ther point, what do peopele use to grind custom shaper cutters – I used to use a narrow grinder on the Elu. but now…
What’s good?

I used rough grind them on a 36 grit grey wheel and finish grind on the narrow white aluminum oxide wheels on a grinder or mandrel with a good tool rest. It was often necessary to use a dresser to shape the wheel to get into profiles.

Elu bench grinder.. I have no idea what it is but if it has a motor that died SOMBODY can rewind it.. I'd look around for a motor shop with a OLD owner.. Sure it can be fixed..
Tim,
Welcome back to woodworking after 15 years!
I'm about to start grinding my own cutters as well and if you want to spend $750, you can buy a machine to do it from a template, otherwise it seems as if the normal bench grinder is the way to go and do it free hand.
If you have lost a capacitor, those are easy to replace, if you are talking about the motor, then it's probably worth your while to buy a new grinder.
About drawing out the temper, 3" away from the grinder, either have patience by dipping into water frequently, or use steel which you can harden afterwards by heating and quenching in oil.
