CA proper application tips please
 

Greetings, Be very interested in hearing some tips/experiences using thin CA
Over application even when using tip extender seem to be somewhat of a problem.
I don't want CA on me and definitely not on my planes where it's not suppose to be.
Thanks for ur suggestions.

CA tips like the ones here: http://www2.towerhobbies.com/cgi-bin...?&I=LXK295&P=7

Make sure they are securely seated on the CA bottle tip. You should be able to dispense a drop, or less, at a time. I find they are more accurate (easier to direct the flow) if I cut them to about 1 1/2 inches in length.

The CA must be cleared after use by squeezing the bottle and letting air eject/withdraw from the tip. When they start to clog, if you keep them emmersed in a baby food jar of acetone, the solvent will keep them clear.

Different manufacturers seem to make different diameter tubes and you want small diameter ones. You may have to try more than one brand.

If you have access to teflon micro tubing it will work also, but, you need to seal it with microballons or baking soda where it enters the bottle tip. If you have access to the same size as the tip, you can make your own dispensers with a little heat, used to pull it and extrude it to a smaller diameter.

JR, I've been using some tips from Tower, but they don't look like the ones you've supplied
a link too.
I'm going to check my LHS and see if I can round up some like you've suggested.
Thanks Much

The Hobbico ca tips fits my pacer ca bottles well. Soak the used ones in acetone overnight to clean the dried ca, and you have a reusable tip that will last quite a while.

Thin plastic (I doubt its teflon) tubing is available. We called it capillary tubing when I was in the lab field and my LHS stocks lengths of it. I bought some that was marked Acorn Industries, but I don't know if they still sell it. The advantage of the tubing is you can get into corners VERY easily and run beads of thin CA a lot more conveniently than with the other add-on tips (these are from lab suppliers too and are called pipette tips. These are polyethylene and I've found they tend to waste more CA than the tubing.

To use it - cut the very tip off your CA tip. Maybe 1/8 inch max, cut a 2" length of tubing at an angle and push it down into the tip about 1/2". If the fit is too loose, very carefully heat the tip of the CA nozzle and squeeze it together. Like the prior post said, you don't want CA coming out around the tip or you're going to have a real mess. If the tubing clogs, first try and twist it off the tubing with your fingers. If that doesn't work easily (like its been there a week), then just cut off about 1/8 inch of tubing and the hardened CA will generally pull off easily.

Just be careful pulling off the CA - you don't want to pull the tubing out of the tip.

Here are the one's that I use.

By only removing the glue from the bottle rather than capping it, I find that the smaller amount is easier to handle. Light pressure on the bulb is all that is needed to get small drops to come out. I also hold the tip of the applicator about 1/8" away from the balsa surface and let it drip. If you place it right on the surface, it has a tendency to draw out of the applicator and can dump a lot all at once. The stuff will run anyway, so the drip method works much better in the long run.
