It is unusual for epoxy not to stick. Pocket eh? Take a Q-tip with
either lye or muriatic acid and etch. Then wash with water, then
degrease with iso-propanol, trichoroethylene, perchlor (dry cleaning
solvent), etc. This assumes the pocket is aluminum which is amphoteric.
... reactive with either acid or base. If it is steel then think I'd
polish with a dremel. At room temp JB-weld will cure out well in 24 hrs.
Every 10 C down halves the reaction rate. If you can position quickly
the 5 min Devcon or equivalent (clear) should work. If you can clamp it
in position after adjusting quadrature then raising the temp will do
good things. I routinely cure at approx 150 F. NOTE: have no idea what
the max storage temp is on the device. ;-)
I've used JB-weld to mount blocks for a scope. ... need to remove them
.... heat to 250 F and then apply chisel or screwdriver. Even then it
can take a decent hit to break them loose.
BTW - I've had pretty good luck with lacquer thinner as a degreaser.
Brownells recommends gasoline as a degreaser for their bluing kits.
Hope this helps. Hang in there. as always YMMV.
Advice is always worth about what you pay for it. ;-)

Gene,
I have seen this advertised several times but have never tried it. I saw
the same type of stuff used on my son's knocked out tooth. The dentist
glued it to the adjoining teeth. It lasted in that environment for over a
year.

This is not exactly the same thing but it is close.

Greetings all;
This is turning into a PITA.
After a weeks cure time I went to remove the blown ATS-667 from that
pocket in my bracket, using a 1/4" wood chisel and a very small bit of
alu for a hammer, it came loose so easy I could have just lifted the
leads by hand. This was with the pocket scratched up with my pocket
knife and washed down with brake cleaner before applying the jbfastweld.
Anybody got a foolproof method of making it stick?
Anodize it maybe.
Quick recipe for that?
Then use the slow jbweld to give me time to adjust some 0-80 screws to
push it around till the quadrature is good. Then ignore it for a week to
cure...
Cheers, Gene Heskett
