I assume that taking it apart to put in a helicoil or Keensert
takes too long.
What about making a replacement part complete with keensert and
just remove and replace. Might be faster than putting a keensert
in the existing part.
There is crazy glue used in place of stitches in surgery. Don't
know if it is food safe, but I would think it is. Maybe contact
your local emergency room to find out if the stuff used for
surgery is food safe and where to get it.
And then there is something like putting a wooden match stick in a
stripped out screw hole. Maybe aluminum wire or wood from a
wooden dowel.
I expect none of the above is possible, but they might give you an
idea of something that is possible.

Oh yes , filing a flat or drilling a dimple so the set screw is not
trying to grip a smooth shaft.

I appreciate the suggestions, but I guess i wasn't clear. The part
does not have a setscrew to hold it on the shaft, it has a clamping
screw to squeeze its split hole onto the shaft, and it can't squeeze
tight enough.
I have thought about running a hacksaw blade through the slot to allow
for more squeeze, but the hole itself is pretty well buggered, and
squeezing tighter will make for less contact area, I think.
Surprisingly, the cyanoacrylates used in surgery are not designated
food safe, neither are the UV curing acrylics used in dentistry.
Apparently something has changed recently about this, as I see many
references on the web to adhesives that are food safe, and then
checking the manufacturer's sites, see that they specifically point
out that they are NOT food safe. Rhino glue is one example. Lots of
references in various forums, but manufacture is very specific in
saying that it is NOT food safe.
while I agree that this is an example of too much government
(actually, it's just two parts of the same agency (FDA) not being on
the same page), I can't use anything that isn't documented food safe
on these machines.
what I may try is drilling the hole round again, and then making a
sleeve of shim stock to snug it up. What do y'll think about that?
===========================
I did that a few days ago to replace a missing and out-of-dealer-stock
Nyliner bushing on my new-to-me 1995 snowthrower. The job took much
longer than 10 minutes, mostly in setup, as in locating the center of
the worn original hole. Had it been more precise machinery I would
have single-point bored the hole because drill bits follow what's
there.

There's a metal version meant to repair worn shafts. The local bearing
supply store has one displayed in their lobby but I don't remember who
makes them.
