A new experience with CA.

In all my years of model building, have never run accross this experience. Yesterday I was glueing mounting blocks on my Smit Nederland to mount a geared down winch. Using CA adhesive, all went well. Today, continuing on with my winch install, while glueing down some more blocks, I find that the adhesive had lost its "sticktivity" Held it for 5 min. and still not sticking. Have left it overnight and hopefully will have stuck. I found that I had left the cap off overnight. Could this cause it to lose its quick dry capabilities? Anyone else run into this problem?

I leave mine uncapped all the time, no issue. Sometimes there's too much air in the joint, like with porous oak or mahogany... CA kicker takes care of it.

Norm, no issue, sorry to say but it's all your own fault for leaving the lid off. The stickum stuff in superglue evaporates leaving the carrier which won't glue; and the stuff will go off unexpectely if it's a bit old.

Many of us have been lucky. I've been lucky too, it sometimes seems to be a bit of a lottery. That could have something todo with the stuf I buy from the Cheap and Cheerful type shops in packs of 7 for $2. But the Industrial Chemist who wrote the item on the stuff I saw a while back said that the active ingredient doesn't last forever, that it can go off readily in warm weather (I can confirm that) even in an unopened container kept in the fridge. Tried it - 2 years later and it stuck like...it didn't.

I tried to take the tip off one of my fingers a few years ago. Dumb. The Doc said that stiches were going to be a bit fiddly so he'd glue it back. He did, with a "medical grade" superglue (heaps more expensive than my model stuff with the same ingredients on the label?) but the nurse had to peel me off the ceiling.

Hurt? Man, you wouldn't want to know. Which is why he "forgot" to tell me first!

Like in the Sun, keep yer tophat on.

Thanks ADAGIO. I used it the next day with no problem. I think it was like Patmat said. "Too much air between the contact surface." The wood I was cementing was old balsam plywood and very porous. Thanks to all

I think PAT hit the nail on the head, with the wood being to porous for gluing. We tell our customers to run a bead of CA glue on the open end grain of the light ply wood frames in our kits, before they start the sub planking of the balsa.

Usually it is the other way around with the CA glues, where you start gluing your fingers to the hull, or even worst, to each other.

Ha ha, I learned a while back that it is a fool’s errand to argue with what works… Thank you for the tip sir.
