You might try the glue used for plastic plumbing; it seems to do a rather nice job, and should be available at any plumbing or home improvement store. chris wrote:

Glues are moderately sensitive to being matched to the material they're being used with. If your gear is actually nylon, virtually no glues will work with it. If it's ABS, you should use ABS solvents/cements. I think PVC and ABS are pretty interchangable, but I'm not an expert at plastics, by any means. As I understand it, there are two types of gluing. Some glues use the porosity of the material, and "bond" by filling in the small voids. A large scale example would be epoxying something to a cinderblock. The glue gets in the voids, and the odd shapes all a structural bond to form. Very smooth materials do not do well with this. Other glues, like for PVC and ABS work by actually dissolving the material, and forming a molecular bond. Materials like nylon to not lend themselves well to this. Some glues, like Superglue, form a third kind of bond. They don't dissolve the materials, nor to they fill the interstitial voids. Superglue is also a very poor structural glue, and not well suited to bonds that are subjected to cross-loading or shear forces. This is just the little bit I know about certain glue characteristics. Bonding materials is a science unto itself, and while I often don't know what glue is appropriate, I've learned the hardway which ones don't (well, except for JBWeld. You can do damn near anything with that stuff). --John On Monday 03 November 2003 11:19 am, chris wrote:

The best plastic glue that I've found is plain old PVC cement like you buy to glue PVC pipe together with. The clear stuff seems to work slightly better than the colored stuff. You can buy it at Home Depot or any hardware store. It cost about $1/ 4 oz can. BUT I've found that once you glue something with a glue that doesn't hold even the right glue won't work. In other words you'd better get it right the first time! Gears are tough, they're usually made of nylon and I don't think any glue will work on it. Joe At 11:19 AM 11/3/03 -0500, you wrote:

I've found Loctite 406 - superglue for plastics and rubber to be very good , I buy it locally in the UPVC window centre - costs about ?5 for a 20g bottle - about $7.50 American. http://content.loctite-europe.com/ceemesa/lctww/USA_center.htm http://www.henkel.com/int_henkel/adhesives/index.cfm Appears that Henkel own Loctite, above links may be of interest.
