I'm looking for opinions /suggestions on which adhesive ya'll prefer to use for kadee knuckle springs. I have a bottle of cyanoacrylate that is Labeled as a 'gap filling' formula. Not yet sure that I'd want to use that in this situation.

I always put just a little touch of that AC glue on the end of the spring to keep it from jumping out of the coupler.

Gap filling glue would fill the gaps in the spring, so I would not use that type.....

To be honest, the only time I've had to place/replace the spring into the coupler is when a spring is missing right out of the package.....I've never had a spring come out during actual use....

But maybe I'm just lucky.....:p

I would say you want thin CA (not the gap filling kind; I keep a bottle of each on hand). Put a small drop on the end of a toothpick and drop it on the end of the spring.

I agree with D&J. I used the gel type CA with
a toothpick to place a tiny dab on one end of the spring.
I never had a problem with it. Did not affect operation
of the knuckles. It's also helpful to do that on the nub
when installing a new spring...let it set before seating the
spring on the upper nub.

Backing a train too hard into a Kadee often causes
the spring to take wing...the glue ended that.

Thanks guys. Greatful here. Gel type CA it shall be. "Now where are my 'readers'? Cannot see the tiny nubs without em."

I think the only reason for the glue is to prevent its loss during insertion. There are probably other way to accomplish this without using glue, like putting a thread thru the spring and somehow removing it.

I backed out so hard that I just gave up and sold
my layout. :sold: Well, that wasn't the reason,
I was just tuckered out and couldn't give it the TLC
needed. It now has a happy new owner now downstate.
