What is this tool?

[ebinmaine 74,806]

This was with a bench grinder we just got from an auction.

It has 4 separate "gear" rollers? that move independently of one another. 

 

A stone dressing tool of some sort?

That's a dressing tool for your grinding wheels. To true up the face of the stone.

Best if you have a solid guide you can rest against to stay flat with the face of the stone.

     I have better results using the single diamond point dresser.   Working the stop against the grinder work rest.

Here's the machine. 

Two solid guides. Two different stones at two different angles.

I have a couple much smaller dressing tools made from square stock coated with diamond grit. 

Never used a round ended one.

Curiously I never liked using either type. I use and have great results using an old used diamond cutting saw blade. I find it easier to control  and more versatile being able to use the very tip or the sides. Easier to control with faster results.

Similar to the one I have... I did have to disassemble it to add a washer spacer at one end of the stack to limit the amount of "wander" the wheels had. That improved the wheel finish.

I thought for a minute that the wheel on the right of your grinder was green, not gray. Green is for dressing carbide - and that wheel is expensive...

Not much for stone wheels, installed a 6 inch flap disc. It self levels. 

I really have no need to sharpen tooling tho. About once a year I can reinstall a wheel and do the saved up bits etc, and have a session.

Interesting thought. 

I could do that too.  

 

What grit wheel do you use? 

[lynnmor 8,122]

Your wheel dresser may need new star wheels.  This type of dresser works well if you are grinding things that quickly load up the wheel, they quickly clean and true the wheel but the dust can be incredible.

The one slightly less abrasive than the temperament of an ex-wife!!

Yup. Those wheels wear as does the stone wheel.

Nope - coarser than that!!

[JoeM 9,007]

I have an 80 on it now but 40 is best for what I do. Got to check to see if the wheel comes with spacer bushings to fit the grinder shaft, I had a set from before and can't remember is these came with or without. 

[8ntruck 8,218]

Check to make sure you are not going to exceed the max rpm on the flap wheel.  'Ring' your stone wheels before mounting to confirm they are not cracked.

What's your average usage for a bench grinder?

I debur metal stuff, edges, holes etc. the flap works real nice for sharping axes, mower blades too. I did use it some on small parts to take off some paint along with a wire wheel on the other side of the grinder. Kind of the clean up center.

Pretty much identical to our usage here.  

 

Definitely a worthwhile looksee into the flapper for me.

@ebinmaine I’d put a wire wheel on one side. I’ve used my father’s more times than I can count to clean up bolts, parts and to de paint parts. It really comes in handy

Oh I have a couple already.  

 

I may have a bench grinder hoarding problem too. 

 

This is number four. 

 

Four different sizes.

Got to remember that wire wheels can grab a part out of whatever you were holding it with and throw it in into an orthogonal dimension never to be seen again quicker than you can believe

I've done this. 

And I've learned. 

 

And I've done it again and again.  

 

So obviously I've learned nothing.

I believe they go wherever those lost socks from the dryer go! Or, maybe with those little springs that are never seen again once they fly out. No one ever finds random socks or springs once they're lost.

Or the little steel balls from the shifter forks.
