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?

Look in Yellow Pages for 'electric motor repair'. Or call a furnace
company and ask where they take their blower motors for repair or
swapout. Furnaces, air handlers, table saws, etc- the motors are all
pretty similar. The motor shop will have or know where to get all sorts
of doo-dads to adapt shafts as needed. If there is an industrial park in
your town, one of the buildings there is probably an industrial parts
supply house- they will also likely have it. As would a farm equipment
store, or a more rural ma'n'pa hardware store. A modern civilian big-box
place has no interest in selling repair parts- they want to sell you a
new grinder instead.

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

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 :-) :D

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?
