Three suggestions for removing super glue:
1. Acetone. Finger nail polish remover contains acetone.
2. Debonder. (super glue debonder) Find this at better hobby shops that sell model airplane supplies,
or try mail ordering.
3. Nitro methane. This may be a little difficult to find. It's the main ingredient in debonder.

Use less glue? Jig up and pin down the parts before you glue?

Seriously, you shouldn't be using so much glue you get much on your fingers. If you pin down your parts to the plan beforehand, you only need a little glue and then let it dry. If you use the thin CA it wicks nicely between the joints. Also apply glue with a micro glue applicator so you don't get your fingers near it, and don't apply too much. The micro glue applicator isn't anything fancy, its two pins stuck through a stick that come together in a with the points to a V. Put a drop of glue on your wax paper somewhere you won't forget, pick up glue with applicator tips, transfer to joint. One drop should cover multiple joints if properly made.

This probably sounds bizarre, but I found that if I did the dinner dishes after building a bridge last year, a lot of the glue on my fingers came off. Dish soap seemed to work well for me.

Otherwise, I'd agree with Blue Cobra: get used to it. : )
I guess since I've been building for so long that's I've gotten used to having glue on my fingers, but if you don't have any special soaps or whatever else to use, I agree with Aia, just washing your hands a lot works fine. They'll feel a little weird for a bit, but by the next day it should go away.

Usually it just reminds me that I've done good work though :)

Yeah, mostly I've learned to live with it, although it makes playing violin a bit hard. Nail files also seem to work, but they're not very effective.

Has anyone else built a bridge to new specs yet?

I'm probably going to start next week, since we just started our meetings this past thursday. :?

May i suggest Nail polish remover it works fairly well at removing glue if you really want to get rid just put a little on a paper towel/rad and rub it come off

normally i just let it be unless it was really annoying

The gyourkoshaven and eyeball treatment is to soak your fingers in warm soapy water, and chip the glue off while they're submerged. (We did this way too many times for a plane that wouldn't come close to meeting wright stuff specs. :lol: )

CA=epoxy, correct?
on another note:
how fast should a good epoxy take to set? or whatever the time on the bottle means.

No. CA is cyanoacrylate, commonly known as super glue. It bonds almost instantaneously - within a second or two for thin CA, and within less than a minute for thicker CA's. It should be noted that it takes longer to reach full strength, however, so don't test immediately.

Epoxy is a polymer that you create by mixing a resin with a hardener. The hardener reacts with the resin to form covalent bonds, creating a polymer. Epoxy can take any amount of time to cure, depending on which type you use. You can get epoxies that take minutes to cure ("five minute epoxy") or ones that take up to a day. The rate at which it cures is determined by the specific resin and hardener, and the temperature at which curing takes place.

Epoxy, however, is not good to use for balsa building events. It will not bond very well to the porous wood.
