Easy to make thin CA applicator:
Cut off the top of a needle eye and sharpen it to a point. (Don't use sprue cutters to do this.)
Drill a hole in a wood dowel around 1/2" deep.
Coat the bottom of the needle in epoxy and stick it into the hole. Let it dry for a full 24 hours. (Don't use CA; it's not strong enough and will be damaged if you use CA debonder to clean the needle.)
Coat the handle with polyurethane to make it resistant to most solvents if you have to use a solvent to clear the needle. (It will also look and feel better. I used a stain/polyurethane mix.)
It's best to not let the CA dry on the applicator. Wipe it off with a paper towel after each use. The paper towel will rapidly absorb any thin CA on it. If CA does dry on it, you can manually scrape it off or use a CA debonder. I've heard you can also clean it off with a lighter, but I have never tried this.
