Gluing Gears

Has anyone found a way to glue ZipZaps gears together to make compound gear sets? They appear to be Nylon or something similar and CA, Etc. does not work well.
Thanks,
Hugo

Yes, I have. I have rebuilt gears with success by abrading the surfaces and joining them with CA.

Thanks Chili,
That's what worked best for me also but I was hoping there was something better. It doesn't always hold.

yeah, luckily it doesn't! my fingers are thankful for that! jk

have you tried JB Quick? I've used JB Weld to hold a magnet unto a driveshaft before......

Do you mean JB Kwik, the fast setting Liquid Steel/Epoxy mix? I haven't tried any epoxies. Do they work on Nylon?

I would assume so. Another forum/site has a tip on using it at the rear axles (bits & ZZs) to repair the plastic slots that the axles snap into. If it sticks to that , I don't see why not. And since it is thinner, it should not add to much rotating mass.
If it was me, I would scuff up the gears w/ sand paper and use CA.

Thanks ibjamn,

The scuff it up & CA is the best method I have found so far but it only holds about 2/3 of the time so I am looking for something better. As for the chassis, it is molded from something different than the gears and CA and even good old Testors plastic cement works there.
