of dressing the green silica(?) grinding wheels used for Carbide lathe

Many thanks.

Pets have owners. Cats have staff.

My personal choice has always been with a dressing stick. As much as some
rave on about star dressers, they are very wasteful of grinding wheels, and
difficult to use in getting a grinding wheel to run true, something that is
very important when grinding toolbits. Dressing sticks (the sintered
type, not the solid boron carbide variety) will leave a sharp surface,
almost as good as the star dresser type, and will do it without wasting any
of the wheel. You're likely to not see any difference between one dressed
with a star dresser and the other with a dressing stick in how they cut but
you will see the difference in how well the wheel turns out.

Dressing green silicon wheels (and black ones as well) is very bad for your
health (silicosis). Breathing the dust should be avoided at all costs.
Dressing with a star dresser really compounds the problem because so much
more of the wheel is wasted.

For dressing the wheels on bench grinders I have always liked the clustered
diamond ones. The rectangular ones about 3/8 x 1" with a handle, looks like a T
with a real narrow top.

How's the snow, Harold?
