I need to repair some cracked unobtainium nylon parts. Anybody found any adhesive or solvent cement that will work on polyamides like nylon?
Other suggestions?

Rich having delt with Nylon parts in Model airplanes for years I can tell you I have NEVER heard of a way to glue it.
What are the parts? Is it possible to recreate them? I have some block nylon as well as some other materials that would easily make a replacement.
Unless they are gears or something super hard to create maybe me and my skills can be of aid. I have spent 35 years making little thing from Control Line model airplanes to handmade knives (for a living for 14 years) to houses.
Be glad to help.

Rich, as of yet I haven't found anything to glue the idler parts.
This is to what you are referring, right?
hot melt glue I was going to try
Ultra-Tac Polyamide Glue Sticks
Formulated for ultra high demand adhesive applications, this polyamide based glue stick stands up to high temperature, harsh climates and sticks like crazy to anything it touches!
Great for auto repair, high stress joints, construction and hot, humid environments. Will join PVC, nylon, wood, metal, and urethanes. Resistant to plasticizers.
This is an extremely aggressive glue which possesses the working characteristics of epoxy but without the mixing. Sets up like epoxy, but there is no waiting for it to dry.
The solvent for this commercial grade glue is acetone. Must be kept in air tight container.
Specifications:
- Recommended application temp: 375 degrees F
- Softening point: 265 degrees F
- Open time: approx. 40 seconds
- Color: amber translucent
- Size: 7/16" diameter, 12" length
Otherwise I'm thinking of JB Weld
I'm not too far behind schedule for re-opening those CT-F9191's in January.
Med equipment, scopes and spectrum analyzers are working and will be listed on epay soon.

hold the presses!
You should always look at the "Glue of the Month" page. link:

They have a glue for hard to stick plastics like nylon.

Surehold Plastic Surgery Seems to Do the Job
I went out and picked up a tube of the Surehold Plastic Surgery. By golly, for the 1st time, I have an adhesive that actually grabs ahold of nylon (at least my test pieces, like washers, and other small nylon parts). It actually has some pretty good shear-strength, too. I was able to separate the parts, but, the glue had not had more than a few minutes to cure. I have some more test joints curing, which I will test tonight. So far, it looks like it will do what I need it to do.
I'll keep ya posted...

So, 3 years later, is that Plastic Surgery glue working on nylon?
Plastic surgery has worked. It grabs nylon, but some tasks are not properly addressed by an adhesive solution. I have used it successfully in alot of applications, but it is not as good as an uncracked part in many. This adhesive has taken a firm place in my toolbox, but it is not the panacea for modern man. Where superglue can be expected to be effective if it sticks, this is a good solution. It does stick to nylon.

So, a broken part which is supposed to hold an high-tension spring would not work I guess...
I've already used JB Weld successfully on nylon, but it wouldn't really stick to it, the only solution was to make hooks with the epoxy that would keep the two nylon parts from separating even if the epoxy would stop sticking to the part.
Doesn't sound good... I've never got Crazy Glue to work on any plastics without melting them beyond any possibilities of repairing them anymore, or it would just stick poorly and break easily.

If you ever want to get an idea of what cyanoacrylate (CA) glues are capable of, you need to buy good CA glue. The RC airplane folks, e.g., know this... they have a lot of $ riding on their glue joints! Buy yourself a bottle each of thin, medium, and thick CA, as well as some spray accelerant and debonder (just in case!). Try these guys.

I just did some cat-destruction-repair jobs myself this weekend... using thick CA and 30 minute epoxy, depending on the particular disaster I was repairing.
Glues are really cool; you cannot have too many different kinds!
EDIT: Here you go... the gift pack
The holidays are just around the corner...

Here's an interesting post on reconstructing parts from JB Weld. Start reading at post #21. I'm not sure if this will work for your application but it is an interesting approach.

Regular cyanoacrylate (super glue) will not adhere to nylon. Plastic-Surgery is a special formulation that does adhere to nylon. The limitation is the same as it would be for normal cyanoacrylate with something it will adhere to. If load will be sideways to the glued joint glueing might not be the solution, depending on that load. Cyanoacrylate also does not have great shock strength, in that if it will receive impacts, it may let go, depending on the intensity of the shock.

I know this is an old thread but I have a nylon gear in a Technics SL-B2 that I need to repair or replace, has anyone found a really good glue to fix a nylon gear? The million dollar question...
Cheers
