So, after I made the Soundwave paper model, I decided I would try to make some of my other favorite toys, Frenzy and Rumble, Soundwave's transformable cassettes! I was trying to make them so that they could fit into the Soundwave paper model. I'm sure they can, save for a little adjustment to enlarge Soundwave's chest cavity. Anyway, these are just work in progress pictures. I haven't picked this piece up in years, but one day I will finish it! The problem I'm having is with the spring up head. I've tried numerous things, like a paper spring, a sliding head, etc. but they don't seem to work. I might have to make the head removeable, i.e. you only put it in when in robot mode. Or I might just have to go with a metal spring. I was very pleased with the way the guns turned out!
