Thread: GMF 6'' Junior bench grinder

Well I pulled it to bits, cleaned and re-greased the bearings and painted the casing. It now looks and runs great. Now I need some 150x13mm grinding wheels to mount on it.

As I'll be mostly grinding HSS lathe cutters and the odd chisel, I was thinking of going for a white alum oxide wheel. Norton make some fancy blue and pink wheels, but from what I've read about them they probably need some serious power to drive them given the aggressive grinding rate they give.

Anorak Bob posted a scan of a Norton brochure recently and it looks like Norton don't make a 150x13mm wheel in white alum oxide. They do make the pink, blue and off-white wheels in that size though:

Can anyone suggest which type & grit should I fit to each end of the grinder taking into account the 1/2hp rating and intended usage?

Hi Jack,
H&F's have these ones

You could make a bush to bring it down to you spindle size, they may even come with one or sell them separately.

If not I am sure someone on here close to you could spin a couple up for cheap or nothing. I would do them if you where closer, but if you get stuck it will only cost you postage from me.

Hi Dave,
I saw those, but unfortunately they are 25mm wide. My little grinder only takes 1/2" wide wheels. Any wider and the outer flange is riding on the threaded part of the spindle.

You can buy depressed centre wheels that can be used to grind on the side of the wheel as well. It would be the best of both worlds then as you could make up a tool rest on the front and one for the side.

Thanks Dave,
I've been searching for depressed centre wheels. Haven't found one in 150mm yet, but I'll keep looking.
