Columbia fiber gear...

Gluing a Columbia fiber gear. This simple repair has now gotten the best of me for a second time.
I separated the gears, cleaned and degreased, then used a liquid epoxy, the kind that comes in syringe type and when you depress the plunger it comes out, then you mix and apply. I cant get it to hold the gear. The gear still slips. Any idea what to use?
It was a five minute type epoxy, I waited 24 hours till reassembly.. I used a de greaser, the parts were clean and grease/oil/dirt free!

Have you tried cyanoacrylate ("Super Glue")?

Superglue? you mean the one drop can glue an elephant to anything?
Never tried it

JB Weld is very good epoxy. It has held things that I never imagined any epoxy could.

Usually I scuff up the surface of whatever I am using it on, so that it has something to grab onto.

C.A. works well in some applications (I have used it to reconstruct two phonograph cases damaged in shipping). It come in several viscosities-the thinnest works best if the parts are assembled first and the glue is allowed to flow in through capillary action. The thickest is applied to both parts, then the parts are joined. There are spray bottles of "kicker" which make the glue dry much faster (usually leaving a hard, white residue).
