I posted the other day about a K-Line truck that had snapped the pin off that holds the idler gear(?).

About month ago we had something break and a friend recommended this Loctite Super Glue Jel. After trying what seems like a hundred different super glues I didn't give it much hope, but it worked. It also saved a couple other items I thought were lost.

Loctite

You can see the little bit of post left in picture 2. I cleaned both surfaces, applied the Loctite and waited the 24 hour complete cure time. Popped the engine around the tree and a half hour later its holding. Needless to say I'm impressed and thought I would share.

My "go to" CA adhesives are Loctite 416 for general work.

I use Loctite 380 Blackmax for when I need the glue to blend in with a black shell.

If you want your CA adhesive to last longer, store it in the fridge.

I'm waiting on an order for Loctite 480, it sounded interesting.  It actually sounds like it may be the replacement for #380, so I figured I'd have a look.

My glue for anything i want to stay together is Loctite 380. A few years ago while gluing two pieces of brass together, I accidentally miss-aligned them. The next day when i noticed my mistake, it took a Zona saw to get them apart. FYI it is NOT distributed through the big box retail, auto parts, or home center channels. I buy mine from Grainger's.

I use Loctite for general applications where the parts stay together easily w/o loosening up and Dap Rapid Fuse for applications where a quicker a set-up is required - like gluing people to the layout.

I also like using a CA accelerator ("zip kicker") where an instant bond is desired. They come in brush-on bottles and spray cans and can be helpful where three hands are needed. I have not found the bond to be any weaker using an accelerator and it can speed up assembly time on many projects.

@GRJ

Having used CA in an industrial and medical environment, what GRJ says is absolutely dead on.

GRJ - consider using 425, its a threadlocker for plastic threads but it is a CA with primer that works well on the slick plastics.

John where to you get it as it is pricey?

This thread has been an eye-opener for me.  I've been using Zap-a-Gap CA glue and I'm becoming more and more frustrated at how the nozzles clog up and eventually become unusual while I still have a half bottle or more left to go.  I have to unclog the nozzles with a pin over and over.  Is Loctitite 380 an equivalent to Zap-a-Gap (which I like other than for the clogging problem)?

I've never used Zap-A-Gap; but i buy Loctite 380 in the 3g tube and never have had trouble with it clogging. I use about 2-3 tubes a year now that my model building (repairing) has slowed down. I keep it hidden in an unused empty pill bottle in the fridge near the train room. As i said i buy it at Graingers for about $8 a tube. It often can be found at other industrial supply houses. Be wary of the low priced stuff on the internet as it may be close to expiring.

Without picking a fight, remember this thread is about better super glue; expect to pay more.  Both GRJ and I are engineers with professional experience using CA.

For those planning to try out the Loctite industrial adhesives I suggest you also get a bottle of Loctite X-NMS which is the solvent for these adhesives.  Acetone doesn't touch this stuff.

You need to get some applicator tips for your Zap-a-Gap bottle.  These greatly extend the use of a bottle of Zap-a-Gap, can be trimmed if/when they clog, and also permit far greater control of the application. As a chemist, I've used these for many years for CA without having a clogged bottle nor have I had any bottles go bad or solidify.  Knowing and applying proper storage of CA is critical to maintaining its potency.

That is awesome. I didn't know those existed. Thanks! I have some on order.

I'm using these tips now and they are tremendous.  Thank you very much for the idea.

I've had my best results with Loctite products. There was a noticeable difference between Loctite and the "cheap stuff".

Same here. Super glue has never worked worth a _____ for me, and I've tried a bunch of different ones over the years. Just gave up on the stuff, until I started using Loctite. Sounds like others have found the same thing. Have just used Loctite Plastics Bonder so far. Still have to apply it correctly or it may not work, though.

I just ordered and received some Loctite 416 per GRJ and Lou N's advice. It getting close to Chanel perfume country in price (well, relatively speaking, compared to common super glues), but will be absolutely worth it if it's effective and reliable. I'm looking forward to trying it.
