I am looking for a glue that has the drying speed closer to CA glue, doesn't need to be as fast, but can be applied in a gap of, say, 1/16".
Oh, it also needs to be affordable... :)
Why is it when I try to glue a joint with CA glue, if the joint doesn't hold and I try to re-glue it, the glue has no holding power? Its almost like once CA glue is on a surface, the CA glue can't be applied to a spot with dried CA glue on it?
thanks,

Epoxy. There exists thicker consistency CA glue for gap filling. I have bad luck using it, and keeping the bottle clean enough for easy reuse.
Epoxy, while requiring mixing, has been easier for me.
Do you think rubber cement would work? The holding strength doesn't need to be super high, and I would like to find something simple enough that my 7 year old can use it. Mixing epoxy might be a little above his level... Sorry, I didn't mention this in the original post.

A UV curable epoxy can be set in a few seconds without open time restrictions. You need a UV lamp to cure it so it might not be the best choice for a one time job.
First of all, I tried coaching an Odyssey of the Mind team of 10 year olds with CA glue, and it was a nightmare. It is way too easy to glue your fingers together and to rip your skin trying to UNstick them.
I don't recommend that for kids.
What is the application?
E6000?
It's my daughter's perennial go to starting with 2nd grade Girl Scouts, through a decade of Odyssey of the Mind, and longer in serious cosplay costuming (think Comic Con.) There is other glue in the supply box(es), but the E6000 gets used 99+% of the time.
For wood, or other similar materials, hot hide glue. Sticks almost instantly and if strength is not a concern, will fill small gaps. Sands nicely, non toxic. Even better, it's easily reversible if you don't get it right the first time.
I have used a 2-part epoxy from the big box stores with good success. Mix in some saw dust and you are good to go. Attractive price also.
Have you tried "thick" CA glue (gel consistency)? it should work for 1/16" gaps
How about hot glue? The low temp glue and guns are fairly kid safe.
I'm with John on hot glue. I "taught" a small group of 8 years olds last year and we had no issue at all using hot glue guns. Your success will depend a lot on what you are gluing.
I don't think there is much chance of offering a reliable opinion until the OP provides a little more information. The introduction of a young person into the picture could complicate the issue considerably.
Rockler sells a spray can of "activator" for CA glue. You spray it on one piece of wood and apply the glue to the other and you get an instant bond when you press them together. Or, you can apply your glue and put the pieces together and then spray the surface and it will cure the glue.Quote:

If it's an adult doing the gluing, I'd agree with glue-pot hide glue. Or an epoxy filler like JB Weld depending on the materials involved.
