Grinder washers

[Herb G]

My grinder has cupped washers to hold the wheels on. They flare towards the outside and inside of the grinder, taking up a good 3/8".
The wheels that came with my grinder are only 3/4".
Can I replace the flared washer with flat washers & make up the difference to mount 1" thick wheels on the grinder without any problems?

Anyone foresee problems with this idea?

The flanged washers are made to make contact in one place on the outer part of the wheel only. Flat washers could damage the wheel or not support it properly and allow wobble or vibrations that can be dangerous.
Seriously- not a good idea.

That's interesting.  The Oneway balancing system is the same diameter as the flanged washers, but it's totally flat on the side that contacts the wheel.  I think what you really need is contact at least up to the radius of the original flanged washer.  There are also aftermarket precision ground bushings for grinding wheels that have integral washers - again, totally flat contact against the wheel.

You can decide for yourself. You really don't want the wheel to come apart at that speed.  It can kill you very easily.

So, does anyone have a source for cupped washers or flared washers or whatever they are called that are not as offset as mine are?

If I knew what they were actually called, other than grinder wheel washers, I could probably find them easier.

Thanks for any help.

Not a source, but you can use cardboard 'O' cut in and out to simulate the rim of the washers.  I've also seen O rings similarly employed.

Try searching for Belleville washers.

These are thick washers and made for grinding wheels. They won't deform at the nut and put pressure at the center or the hole of the wheel.   https://www.woodturnerscatalog.com/p/97/...ers-2-Pack

Slip a hose washer over the shaft and then install a large flat washer.This simulates a flanged washer.
I did this for a 1" wheel like you described. Been on the grinder about 8 years now.
