Over the past few months I have read articles regarding modelers using hypodermic needles for guns, pitot tubes, and pipe[^] Nowhere am I able to find where to get them[%-)] The last time I checked I was told I had to have a perscription from a doctor to get them[banghead]
Whoa. Don’t have that problem over here. I can get them at the corner drugstore and send them to you… but the shipping will cost more than what’s being shipped. Also, if you have a diabetic friend who is on insulin, maybe you can use one of those (my sister takes insulin every now and again)…
I get them either from my Dr. , Dentist, or Vet. All are obliging, and the biohazard caution mentioned earlier by Iroc should be taken seriously.

The cryostat tubing which I have is miniature aluminum stuff used in cryogenic cooling systems for electronics such as can be found in Hellfire & Javelin missiles, amongst other systems.
I have two varieties, finned and non-finned. The non-finned stuff is good for gun barrels in 48th while the finned stuff, which has steel ribbon wound and welded around it to form cooling gills, is good for oxygen hose in braille scale. It’s too big for 48th, but 32nd is A-O-K. Probably too small for 24th.
Unfortunately, you can’t find this stuff in 'yer average hobby shop!
OK, so having worked in doctor’s offices for the last six years, we’ve disposed of a LOT of used needles. There are many different gagues available - but one thing puzzles me: What’s the best way to cut the tubing to length without crimping and smashing the ends?
