Old Wolf Bench Grinder

[stevec]

I've had a couple of Wolf 7" angle grinders and I think the original colour was a green hammertone.

Hi John,
thanks for the photograph, that was exactly what I was looking for.
If you would be able to get me an emblem for my grider, that would be marvelous!
I attach a picture of my grinder so all can see the state it is in now. Isn't that a good way to emphasize how good looking yours is now?

Stevec: thanks for your input on the original colour. My grinder has that kind of colour on its backside, so maybe the person who painted it was lazy enough to just paint the most visible part and leave the rest alone? I will have to check that out. If that is true, it will be a great opportunity to match the colour.

It may not be obvious from the picture, but I do have the sidecovers for the wheels. You can just see a part of one on the floor in front of the grinder.

Does anyone know what has been mounted to the top of the wheelcovers? there are some holes in mine, but John's seems to have some kind of blocks there. Maybe some kind of guard? I think I see some in the small picture I saw in another thread I found about Johns grinder, but with that size I can't be sure. I don't think machines of this vintage had these plasic "windows" did they?

I do have to find me a 3-phase rotary switch, mine is completely missing. The grinder is attached to an external switch, which works fine for now.
Any chance your friends scrapped grinder still has its switch or the blocks on top of the wheelcovers John?

Is your grinder actually 3 phase? Or do you mean the correct switch should have 3 positions as in forward, off, and reverse?

@stevec:

Yes it is actually 3 phase. The man I got it from had used it in a professional sharpening shop where almost all machines were 3-phase, at least all the older machines (my guess is most were built between 1940 and 1960). And actually I like my machines that way too (both age and electrical).
As far as I can learn from the label where the switch used to be, the functions of the switch used to be the same as John's: turning the switch to the right is "on-off-on-off-on-etc" (that is if you keep turning), to the left is just the same :-)

I guess if I can't find a rotating 3-phase switch I can always use a single phase rotating switch with a three phase magnetic switch behind it. I don't mind upgrading the internals, but like to keep my machines looking as original as possible, and I do like old Iron ;-)

I cleaned the machine, found a temporary switch and wired it to the machine. It runs beautifully! At least now I can use the grinder until I have the parts and the time to do a proper restoration.

Always good to get a project up and running - well done.
