I happen to use some of the quick setting JBweld today. I misspoke,
it is not clear, grayish and black for the two parts. It may be just
carbon black but who knows.
Almost every hardware store has Devcon products, slow setting and fast.
At least some are clear. Sorry for the confusion. IIRC Devcon was pretty
much the first entry into small tubes of 2 part epoxy.

Not directly glue advise. But gear tooth sensor advise. Don't let the
heads of those things rip off and go through my gear head mill's bevel
gear teeth. Not pretty. No teeth broke but there is a surprising
amount of quite hard metal in the middle of something like an Allegro
ATS675 it seems. The gears were nowhere near silent before, but
they're louder now for the experience.

Greetings all;
I went tp play with the lathe after reboot the rpi4 with cpu_freq raised
to 800 megs.
All of a sudden the spindle tach got noisy, then quit. removeing the
heads lid, I could see a good coat of the 5w20 I've been useing for
spindle oil had flung out of the side face of the bronze bearing and
given my encoder assembly a good coat of it.
Removeing it for a better look I found 2 of the 667's loose with
signs of
the bull gear touching them, with one having vibrated enough to break
its wraping wire connections. They were glued into pockets machined in
the mounting bracket which if the glue worked had them spaced about 5
thou away from the bull gear in a curved alu bracket made of of 7075
scrap. I've made a wooden c clamp with a #6 wood screw which is
currently sitting with the point of the screw in the middle of the face
of the loose index generating 667 after the alu was well washed by
acetone and then filling its pocket in the bracket with shoe goop, same
stuff as go-2. And tomorrow I'll do the same with the other.
Cleaned up with acetone of course.
Previous attempts to glue then in place with super glue were very short
lived, loose in a week. Ditto with gelled super glue.
The go-2 lasted about 2 years.
What sort of glue can I use that can withstand an oily environment of
light 00w20 for many years?
Thanks all.
Cheers, Gene Heskett
