CA delivery apparatus

[ed440 at mindspring.com]

Jon-

I just snapped a thin hypodermic needle onto the tip of a 1 ounce bottle of thin CA.

I was able to get fairly small drops, one at a time without the dribble that happens with the thin nylon tip extenders.  The drops were small enough to do a discrete tuning pin job as you described.

To clean it, I filled the syringe body with acetone and squirted it through.  If I had a good supply of needles, I would just toss it after use.
