Does anyone know if there is a way to enlarge a hole from 5/8" to 1"
on a grinding wheel? I have a brand new Norton sg wheel that has a
5/8" hole I would like to use the oneway balancer on it however it has
to be 1" Sure hate to throw this wheel out as it costs about $100
Thanks for any help anyone can provide

don't enlarge the hole, you risk fracturing the wheel and that's dangerous.
Why do you think you need to use the balancer? is the wheel defective in
some way? if it is not, maybe you should consider using it without the
balancer. You will notice that professional machine shops, etc DO NOT use
these balancers - so that suggests to me that they are one of those things
sold to folks who don't really need them

I have used a cheap (or worn out) diamond impregnated saw blade to shape a
grindstone - you can hold it against the face to get it round, and if there
is any wobble, you can trim the sides - at which point the wheel is running
true and at least in my experience, without vibration.

If you want to throw away the wheel, I'm sure that there are folks on this
NG and others that will be pleased to take it from you

What Bill said. I've been a machinist for 38 yrs. You balance a wheel by
making it run true. Faces and OD. Not adding a "balancer".
Never thought of using an old diamond saw blade to true-up a wheel, might
be slow, but should work good. Thanks Bill.

Ok - listen please.

I am into metal mostly, have turned a lot of wood in my life and have
lots of wood tools to my large metal shop.

I have two surface grinders. The grindstones turn at 20-30,000 RPM. FAST.
I have to ring the stone before mounting. Because a tiny flaw is magnified!

Lets say you some how get the hole cut out. Now it has to be balanced.
Then it has to be trued on face and on edge. The hole may not be
co-linear with the other hole.

A wheel explodes with such force it can cut off arms and legs.

A friend of mine at a local large industry (tree harvest) JD house
was grinding something on a large industrial stone. It exploded and
by the grace of God the stone rotated and glanced off his arm. If
the large chunk didn't rotate, the arm would have been just taken off.

So on that wheel - use it as is. It is cheaper to buy a new grinder for
it and a new stone for the balancer.

I'm a little nervous on the need of a balancer.


Stones can be faced - trued up - with a diamond in a rod. These are not
expensive and clean up a wheel nicely.

to me dont be stupid
