Are all small bench grinder wheels crap nowadays? Bought two new wheels for my old 6" B&D bench grinder from the local hardware store. When mounted, both wheels are nearly 1/16" out of true both side to side and OD. Figured maybe the flanges were bad so I turned some new one from round stock to match the ID of the wheels. Mounted them and they were still horribly out. My flanges are jam on, it's the center holes in the wheels that are so bad. Bought a new grinder from HF, yea, I know, cheap China crap, and it is just as bad right out of the box.I just want a general purpose grinder/wire wheel set up that will run decently true without shaking the whole bench, not a tool grinder. Problems seem to be the wheels, not the grinders themselves.Suggestions?
Go on Ebay and look for the commercial brands of grinding wheels/wire
wheels. Imported Chicom stuff tends to be utter crap at the lower end
of the price range. Which means most "hardware store" is crap. Not
all...but most.
Id suggest doing a Ebay search on "Norton" as a start.
I would avoid any ad that claims "norton type"

"carborundrum" is another good name to search for.
Other names to search for:

That being said..you do have a stone dresser...right? This simple
device will allow you to quickly true up ALMOST any properly made
stone.

Lots and lots of them on Ebay. I cannot speak for the diamond
dressing tools. Perhaps others here can.
I should also mention that it is entirely possible to get a ****load
of high quality grinding wheels for free or nearly free. Find a local
grinding house in your area..and bring in a big box of donuts and ask
them for their "old used wheels". Often times they will have boxes of
used wheels that were radius dressed for other jobs that are now over
and the wheels long since paid for..and are now in their way. Its
surprising what will turn up. I once asked at a smaller shop..and was
given 500...yes...half a thousand used grinding wheels. Some of which
appeared to be nearly new..300 were well used. I was giving them away
to my friends for 5 yrs....(Grin). Any idea what 500 wheels weighs?
A ****load!!
Most commerical grinding wheels will have a 1 1/4" center hole to fit
industrial grinding machines..but 5 minutes with your lathe and a bit
of aluminum will turn an adapter with a 1 1/4" od and a center hole
that will fit your spindle.
Its not rocket science in the slightest. Do you know what sort of
grinding you will most be doing?
