What do you use to replace grinder wheel blotter paper?

[Leviton]

I'm refurbishing this hand grinder that my son-in-law picked up for me at a garage sale for $5.

I've got it apart and the blotter paper between the wheel flange and the wheel pretty much disintegrated.

When I put it back together, do you have any suggestions on what to use to replace the blotter paper?

that old, I would replace the wheel

I've used thin cardboard from cereal boxes before. No issues.

Why? It's more of a decorator piece than something that will see any hard use.

ahh. so the cereal box idea gets my vote .

wow, didn't even realize!

By blotter paper I assume that's the paper disc like a shim or cushion? Is that a common correct term for this? I ask because, I would call it a shim because (if I am imagining it correctly) it would probably resemble the shims I use that come with dado stacks, albeit thicker I guess.

Blotter paper was something altogether different, and would definitely not mix well with grinders or dados especially.

Yikes!

What is/was the purpose of the blotter paper? Was it a shim, or did it actually serve to blot?

until very recently, i worked at a very large grinding wheel manufacturer. our blotters were a thin card stock, generally. some were coated, some were basic kraft. I'd probably just cut a cereal box for it, as someone else indicated

the blotter can serve as some cushion and protection for the machine, depending on the application. generally not necessary, but some customers really wanted them

I had to overhaul/clean the carb on my 21" Briggs and Stratton engine lawnmower recently, I used a Heinekin 12-pack bottles cardboard container for the carb to head gasket. It worked perfectly. Similar idea, I wouldn't be surprised to see that the thickness of the beer carton is thicker than the cereal box, which would probably lend longevity to it's re-purposing.

A trip to the recycling bin showed that a cereal box and a Heinekin box both measured 1/64".

Gentlemen, thank for the feedback! I will go cut up a cereal box or 6-pack holder.

Congrats on 10K posts, The Cobbler.

mike93lx, thanks for the first-hand experience information.

For those asking about blotter paper, here is an excerpt from the Norton website:

"Experienced grinding operators know the importance of blotters. Blotters are compressible washers that are placed between abrasive wheels and flanges to prevent the flanges from slipping and protect them from wear. They are also important for wheel safety and are required by the safety code ANSI B7.1.

However, even experienced operators may not realize that blotters are useful for checking the condition of grinding wheel flanges.

Since blotters are compressible by design, when mounted they take on impressions from the surfaces of the wheel and flanges. These impressions provide insights into the flange condition and mounting procedures. So next time you perform a wheel change, check for the blotter."

No problem. Coincidentally, that is who I worked for.

This site never fails to amaze me with the new stuff I learn on a daily basis, thank you!

And congrats, Cobbler, on breaking the 10K mark...

I must be getting old...

I saw blotter paper and instantly thought of my high school/college buddies who were into psychoactive non legal intoxicants.

Good info regarding grinding wheels.

 

[Leviton]

Went with the cereal box instead of the 6-pack.

Looks good. I'd say that is an ANSI-spec cereal box.

Same here.

I have a bunch of old SF posters, including a 'Flying Eyeball' I bought at Bill Graham's factory outlet, many, many years ago. Owsley! The caricatures used to dispense doses often resembled 'cockamamie' temporary tattoos.

I believe these could also serve as the grinder papers.
