White Grinder wheel

**iron bark** · 19th January 2007, 04:47 PM

Just got home with a new white wheel 8" for my grinder. Put it on the grinder and could not believe the amount of runout laterally and seemingly out of round condition.

It is a Norton from Glenfords.

It has different size plastic or nylon arbor rings which all fit inside each other to take the size down drom 1.25" to 0.5". All the errors seem to emanate from these bushes.

Been thinking maybe turn up a wooden or steel centre and fit it in place of the plastic bits to get the wheel to run truer before dressing it.

Any similar experiences and/or fixes

Cheers Ned

The cup washers that hold the wheel in place haven't deformed have they. Sometimes you need to rotate the washers to fix the runout

Thanks DJ,

I have it on and off a few times now, and the runout seems to be almost gone, but still there in varying amounts with each fit, but probably acceptable.

The out of round seems to be the worst feature, and does vary a little, but is certainly excessive. Makes me suspect the nylon arbor inserts even more.

I am still reticent to use the dressing diamond yet until I get a better handle on it

Cheers,

Ned

I put one of the Norton white wheels on an old Skil grinder. No problems at all.

I have found that any wheel you put on will be out of round regardless of brand

Thanks for all replies.

DJ from what you have said about out of round, from your experience would you attack with a diamond dresser at this stage??

That's the way I'm leaning at the moment

Thanks again

Ned

Every new wheel I buy gets dressed regardless of how true or out of round it is

Lee Valley sell a wheel balance kit with a set of machined washers/balance wheels and a nifty rotating jig - I've been meaning to get one (or two), just keep seeing other shineys

Good advice DJ - thanks

bsrlee - just had a look at the Lee Valley website - looks like a good system - balance is everything believe me - I was in the helicopter game for a long time

Is any Lee Valley stuff available in Oz or do you have to import it??

Cheers,

Ned

Ned, refer 's posts in this thread re: mounting a new wheel. Did this with mine (got my first white wheel about 2 mths ago - also a Norton) and minimised the runout, then dressed it with the T-bar diamond dresser.

Quite happy with it now.

Cheers...................Sean
