Best Glue for assembling a balsa model

In the past 15 years, glues have improved dramatically.

The closest to the glue you used to use would be an aliphatic resin. It's a little like PVA to use but the results are much better.

Most of us now use cyanoacrylates for balsa though. Thin for good fitting parts and thick where some gap filling is required. Drop on some baking soda to make strong (but rough) fillets.

So I should go with CA then? Baking Soda? You lost me.

Just like he said. get both thin and "thick" CA, thin bonds in 2 seconds, thick it depends (same for fingers).

Thanks all.

BTW, CA is nasty, nasty stuff. My finger tips are covered in the crap.

It'll peel off in a day or so. Don't worry about it. After a while, you get more skilled at not attaching yourself to the workpiece or to other parts of yourself.

Way to go, Tony.
Just pick your fingers, not your nose or any other body parts whilst using CA.

when you are done using it, i reccomend wiping it off with a paper towel orsometing so the excess doesnt harden. Otherwise you will have to get replacement caps.

I use Sigment glue and titebond glue along with ca. Sigment is the 1950's model airplane glue and titebond is yellow carpenters glue. Ca is super glue. Sigment is best if you have to sand it. It bonds in about an hour and attains full strength overnight. It sands just like balsa. Titebond is cheapest but slowest and stronger than balsa. 24 hours to cure I put these two glue types in a syringe made by "Sig" Epoxy glue is very strong and heavy. I use very little of it. Elmers white glue is used on any foam you may use. Jim Finn

watch out for CA glued joints when first using the stuff....it Always sticks to everything you don't want glued (esp fingers) but doesn't always stick firmly to intended joint material...it can look real neat with no buildup or ooze out but one good "test " pull & the parts come loose again.... i still don't 100 % trust CA as much as the other glues except for sticking body parts together every time....... kw

If you use CA, get the tips as they really help in applying the adhesive. You will also use far less CA with the tips as little gets wasted.

Something like this:

Unfortunately, I've found that I'm slightly allergic to CA, which I hear is common (damn shame as I enjoy building nearly as much as I do tinkering and flying). Anyone found a workaround for allergic reactions to CA?

My 2 cents
Acetone will disolve CA. This is nice if you glue something togather that you don't want. Fingers to fingers, fingers to balsa, ect. You can buy fingernail polish that is 100% acetone. One more thing, acetone and most CA glues will eat foam.

I have a strange number of allergies to adhesives I've found over the years, the best solution is a box of Nitrile gloves from your local drug store, they're super thin, just make sure to get the size that fits you best, nothings worse than dropping a part with glue on it because your glove's loose. I find the best way for fitting is just like golf gloves, they should feel very tight with no floppy finger tips.

I am about to go to the hobby store and buy a Great Planes p-51 .40 size kit and I would like to know the best glue for this plane. I do HATE CA, I just got done building a P-40 Warhawk with CA and it's all over my hands. I want something stronger than CA and I don't mind a little bit of dry time but not too long because I do still want to get it done in a little less than a year... Lol
