Step 26: Platen: More on Plastics
Watch this video from TAP plastics, and/or or this video from me. I apologize for the low production quality of my video. If you haven't welded acrylic before, these are a' must watch. I have found that I vastly prefer using a syringe over the usual applicator, but syringes can be hard to find, and you don't want to pull them from the trash. ;)
UPDATE: From Caitifty, how to find syringes: Pharmacies in California and many other states in the US now legally sell insulin needles (and Canada, most of Europe, Australia etc have done so for decades) - get the smallest gauge they carry (smaller gauge = larger diameter, go figure) and you'll usually find the needle part can be popped off by sliding a knife blade into the gap at the head of the needle, leaving you a very convenient syringe with a 15mm applicator tip. If you're really lucky your pharmacy (or needle exchange - google to see if there's one near you) will carry actual luer lock syringes which don't have needles 'built in'.
