Several comments.
First this guy just bought a Delta toolmakers grinder.
Its is about as light weight as you can get, so advising the guy
to take 5 thou is very bad advice! Believe me, I own the rockwell
version of this machine and it won't do it! Period.

Second. This machine is not equiped with flood coolent. Mist
coolent was an option. I have never tried using coolent because
of health concerns but I'm sure it would work better. I have done
a lot of grinding dry with decent results. Definately a step
up from the milling machine.

The comments (in the post that was copied from a different site) were
directed to a person that was operating a B&S machine, not for the owner of
a Delta. However, everything stated still applies-------perhaps with a
lighter depth of grind. Regardless of how rigidly a grinder is built,
surface finish will be profoundly improved by the method proposed. Coolant
is a must-------it's not a luxury.

I'm not sure I understand your concern for using coolant and your health.
Are you suggesting it's healthier to breath the metal particles than some
mist? You want to remain healthy? Quit working with metals. There's
a given risk for those that do---------it goes with the territory.

When you suggest you've achieved decent results, try selling your results to
a QC department. It's all a matter of what you deem acceptable. My time
on grinding machines tells me that there's no way in hell you'll come close
to the results of grinding wet----and that includes holding dimensions.
Typically, grinding is close tolerance work--work that is rendered nearly
impossible when grinding dry. If, on the other hand, you have no clue
about working to tight tolerances, perhaps that's not a concern. For me, it
was. I'm afraid I'll have to put my years of experience in precision
grinding up against your opinion.
