Talk to your doctor about your need for a syringe... They will often give you one. The huge one you want for gluing a model is obviously not what a "junkie" wants... especially with the huge bore needle.

I use Elmer's Carpenter's glue for most of my wood construction. A quart bttle is inexpensive at the hardware store. (about what they charge for 4 oz of Titebond II in the hobby shop...) A quart will build a LOT of airplanes!
