Same problem here.
To get me out of the woods, I had a piece of 1" x 3/8"aluminium bar
lying around. I cut it to length and drilled a 3/8" hole through it and
then a hole right through the side, to take a M5 tap. I stuck a M5 screw
in each side, in lieu of grub screws and used the hacksaw to cut a
groove in the end of the bar, to act as a pointer.
Rough enough and good enough until something better is found.

I desperately require a knob for my small variac. The shaft is 3/8"
diameter. The max skirt I can handle is
3"...and maybe 3.25" max. At this point I will use anything I can get my hands
on....as long as it has a 3/8" hole for the 3/8" shaft.
I checked my supply of knobs....and they are all the usual 1/4". And none of
em can be machined out to 3/8" either.
If anyone could help, it would be much appreciated. I just require one knob,
thats it.
