Tell us about yourself!
I know this is a very old post, but those of you whom are still following the thread and have been waiting all this time, I might have found something. The guy on this website makes the grinder, compressor, extruder, and injector! All of it is DIY and he has the plans available FOR FREE. It'll still set you back a few hundred dollars, but the ROI is worth it once you're pillaging the neighborhood recycling bins for all their plastic. Once I find a metal working shop in my area, I'm definitely going to at least start shredding the plastic for volume reduction and long term storage. Then I've got to decide if I'm building up or pyrolyzing down the shredded treasure.http://preciousplastic.com/
