What is one or does it do i think my atlas lathe came with one. And my
newbie to the machining side doesnt really get the point of it currently

there is an electric motor attached ot a belt drive attached to an arbor
that ends in a small grinding attachment i assume this is essentially a
toolpost grinder?

But the application of one is still a bit of a mystery to me and i could
stand to be pointed in the right direction.

They are a precision balanced motor with a belt driven spindle with
precision bearings. The assembly provides for speed changes for the size
wheel in question. Not really necessary unless you intend to work with
hardened materials, and not really recommend anyway. You have to grind
dry, which is a grand PITA, and the resulting abrasive plays hell with a
lathe, which has exposed ways, unlike a precision grinder. At best, a
tool post grinder is a compromise. Relatively poor finish (as compared to
a precision grinder) and difficult, at best, to control size (again, as
compared to a precision grinder). As the name implies, they mount on the
compound, where your tool post mounts.

Don't get me wrong. They're a nice tool if you must grind and have no other
options. Just avoid using one if you can. There's lots more neat stuff
you can use for your shop----assuming you don't have a specific need.

Indeed. Ive got a Dumore that I think Ive used (1) time in the 8 or so
years Ive had it.

Now it lives on a shelf because I stumbled into a Covel OD grinder
that is the real deal..and I think Ive used IT 3 times when making
something (Hasetalloy replacements for solenoid valves)

Like the others have stated, its a super tool when needed, but it
makes a mess. Whenever I use mine, I place old bed sheets etc on my
lathe, and use a piece of brown masking paper that I spray oil on so
it attracks and holds the grit the grinder makes, and as much as I
cover my bedways and the rest of the machine it still will find places
to get into that you find months later......

If your TP grinder is made by Atlas, you can get a manual for it from
Clausing, which merged with Atlas a number of years ago. There's a bit of
info in the manual on how to use it AIR.

In one shop we had a dumore 67 toolpost grinder that I used all of the
time. A pretty specific usage, grinding a plasma sprayed seal diameter
on a turboprop engine component. The plasma sprayed metals do not
machine worth a damn and the only way to get a decent finish is to grind
them. I would leave 2-4 thou over finish and still get a little taper
from the wheel wear over a half in of grinding :-) Mind you that was
nothing compared to the wear on the wheels on our Heald internal grinder
used to do the seal segments in the turbine paths, up to .030 on a 6"x2"
alx wheel. We tried using diamond and borazon but it just clogged the
wheel. We found one that worked and then ordered them in batches of 25
from a specialty wheel maker.

Got any pictures?

I was thinking of making one out of a Dremel!
I've had to turn down goddamm dowel pins, so I collet-ed up the pins, and
just held the Dremel by hand!! Worked! At least well enough...

A spin fixture on a surface grinder is probably a better method for the ends
of short hard pieces.

The finish from these grinders can be pretty good. My buddy finishes long
shafts w/ a Dumore
They are a pita, tho, and the grit/dust is a problem. Proly wouldn't hurt
to blanket the ways/machine if using one for extended periods.

You can use carbide to turn down dowell pins. You can part 'em off
too. Even the shanks of endmills and taps can be turned with carbide.

Dremel makes a flexible shaft attachment that is cylindrical and about
5/8" or 3/4" diameter. It fits a boring bar holder nicely.

Do you have a picture that you could post to the drop box at

Alternately, I have an original Atlas/Clausing TP grinder and can put a

You will never have a use for it, and it will be laying around your

THe pic i have is my full lathe with tooling the grinder is kinda small
in comparison but it is in the pic i have

It looks homebrew

a tube with a morot and a speed control switch (Multi position) to a
triple pulley to another to a tube containing the arbor to a grinding
bit (die grinder bit size)

I'll attempt a posting to the drop box

I've turned the flange off of drill bushings when adapting them to
hold odd sized drills in a tool grinder collet. (have to slit them).

Carbide is is great.

Hang around here a while, and you'll see lots of offers to take
"worthless" stuff off your hands. Some are even serious.

All kidding aside, there are things you will run across in your
wanderings that you recognize what it is (or at least you are pretty
sure) that were expensive or rare once, and were worth a pretty penny
once, and you know you'll never use - but you know three people who
can. And the price is right, as in "Get it out of here, it's been
sitting there for 20 Years and I'm sick of looking at it!"

So you haul it off, and you can usually find someone here to pay you
the "Shipping and Handling" costs to get it to a good home, where it
will get used for the intended purpose.

That, or they might have something sitting around taking up space at
their shop that YOU need - What goes around comes around...

And you saved landfill space, too!

So, Steve (the one who runs the Dropbox) renamed it to:
