Well, if you're not joking...you might want to reconsider which types of glue you use.

Hot glue is heavy. Very heavy. So is epoxy. Gorilla glue is fairly heavy but you can get away with it if used correctly. Glue can really add weight to a structure fast though, which is not what you want to do.

Don't know about source of smaller pipettes, but there are other options.

For applying very small amounts of superglue (I assume that's what you want it for). Two pins stuck through a stick. See: http://www.gryffinaero.com/models/ffpag ... yaapp.html

If you aren't using superglue, then something like this might work. http://www.gryffinaero.com/models/ffpag ... ement.html

Finally, you should be able to thin out a plastic pipette with careful application of heat and a little stretch. That's how they used to be made classically. Actually, used to be glass, but plastic will work too.

Hope that helps,

As usual, Jeff is right-on.

There is another option, too. Hobbytown carries (at least our Hobbytown does) extender tips for (CA) glue bottles; fine and extra-fine. They're plastic; base end big enough to fit over the nozzle of a CA glue bottle, with the tip down to a very small hole. Two styles; one that appears to be made by the melting/softening and pulling out process, and the other that appears to be moulded. Cost is like a dollar fifty for 6.

With these, you can get a very small droplet of glue on the end, and apply it right where you want. If the tip plugs up (and they will, periodically), just nip the end off w/ a razor blade. When the remaining tip gets too short, put a new one on.

No, I only use thin CA, doesn't work well at all with medium. Are the pins close together at an acute angle? Was trying to figure out how to show that and noticed the capital V i used later. Needs to be at least as sharp as that V, maybe sharper. The glue sits in the bottom of the V wicked up by capillary action, thus the need to keep the V narrow and the pins very close together.

Note, you pick up the glue where the tips of the pins come together, and drop it off by touching the side of the V the pins make to joint. When we were making Wright Stuff planes, you'd add less than 0.01 gm glue weight to a wing if careful.

Thank you jander, i think my pins were just at a large angle, i'll try to decrease the angle.
