Gene, I think your brain's working too hard!! You probably won't have much success with Insulin needles as the length of thin tube will act as a brake on the oil. One place you can find really small bore tube is on an old fridge - the thermostat bulb which is in the frig compartment is usually coupled to the gubbins in the back with a very small bore copper tube - its full of alcohol or some such.. A short length of this glued into a bigger tube would probably serve your purpose. If you go down this route, I would tap a pointed scriber into the end of the little tube you are going to stick into the bigger tube to make a tapered lead in for the fluid.
To make a swage for any other tube, use a little centre drill - I have them down to about 1/8" OD. Put a bit of steel rod in the lathe chuck and drill a centre drill hole in it, then hold the tube you want to narrow in the tailstock, lubricate the centre drilled hole and, with the lathe running, feed the tube into the hole with pressure from the tailstock. When you've closed it up too much you can file the end back a bit till the hole is the right size. Ian _________________ Ian W.
