If epoxying the gear to the shaft (after thorough cleaning with acetone)
didn't do it, I'd be inclined to try making a shaft that was built up a
little at the pot-metal-gear end, and press the gear onto that.  The hole
in the frame at that end would have to be opened up to match, of course.

Or...

File the shaft to about half-diameter where the gear goes, as flat as
possible.  Use a small round (square?) file to notch the gear hub to accept
a short round (square?) pin that would jam between the gear hub and the
flatted shaft, then a drop of cyanoacrylate to keep the whole thing from
walking away (or maybe use the world's smallest Woodruff key? <g>).  I'm
not sure whether there would be enough clearance to assemble this little
delight...though of course drilling out the frame and putting in a bushing
would solve that.  I'm assuming that the beige gear on the other end ought
to be left severely alone if it's not already coming off...

I don't want to disassemble my existing speedo which is working fine thank
you...but if someone has some junk ones lying about I could play with them
a bit.
