Wow, that's grade A BS. Oh, and someone already did develop a jaw system here besides grusderk, predattack, and itself considerably cheaper than replicating grusder'ks way.
Someone made a YouTube video where it explains how it works, and just by looking at it, I can tell that basically, sticks connecting the jaw to the mandible is turned horizontal when the jaw opens, pushing the mandibles out. I myself am going the hard and rather elitist way by making a simplified version of grusderks, which someone posted a diagram of on various threads. On the noob link list, there's a babelfish link that has pictures, and if you study it, you can get the whole system.
