Absolutely. If you are using a double ended motor, both shafts
turn the same direction and so one is going clockwise the other
counter. You will need one of each to play.

So, now that I know what these things are called, surprise
surprise they are available in many places, even on eBay.
Question: Should I use a left hand threaded shaft on one side of
the motor, and a right hand thread on the other side? Is there a
danger of a grinding wheel coming loose if I don't?

That is *exactly* it! I didn't even know what they were called.
I live in rural Oregon (Lebanon), and all I could get from the
local stores here, as well as our few Big Box stores, was dumb
looks.

Thanks guys - this is why I ask these oddball questions here -
if it's anything remotely related to home repair or any type of
power tool we might use around the home - someone here always
seems to have the answer :-)

I assume this is what you are after to convert a motor shaft to
a right hand or left hand threaded shaft:

I have an old grinder. It is a Dunlap sold by Sears, I'm
guessing in the 60s or 70s. It is essentially a 1/3 horse
electric motor with a 1/2 shaft sticking out each end.
Attached to each shaft is an attachment that is female 1/2
inch on one end, such that it slides over the motor shaft and
is held in place with a set screw. The other end is a threaded
1/2 stud with nut that you slide a grinding wheel (or
whatever) on it and secure with nut. Any wheel or brush or
whatever with a 1/2 hole will fit on this.

I need one of these attachments. I've been to hardware and
auto part stores, and no one that I've found so far has any
clue where I can find one of these. Does anyone have any idea
where I can find such an attachment?
