Plastic Weld Engage!
Here I've done a very terrible thing you should never, ever, ever do, and melted the plastic with my soldering iron. Blame it on the fabulous Epyon's work here: www.airsoftretreat.com/forums/index.php?topic=49814.0
He gave me the idea. You can see from his work how one can build up the welds, and then grind them off smooth to beautiful effect. Soon after this pic was taken, I started grinding off the high points. Cue next slide.
(PS- I also cut off and bent in the apple slicing blades of knuckle death)
