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.

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

Thank you all for your advice. After reading all your postings I am

Just the thought of the stone potentially exploding is enough to say
to me dont be stupid
thanks again
