The chain is made of nylon so it does not add much weight. It has become a little heavy just because of everything packed in it. It weighs 6 pounds. When it is clamped on it fits snugly and feels pretty good.
Thanks all. I'm still monkeying around fabricating points of attachment for the housing. It is a pain. I just got done building a face plate to cover the opening for the blades on the front of the housing. I couldn't really sculpt that part as the exact blade position was impossible to figure during the sculpting process. I'll get a couple more progress photos up this weekend.
Actually the blades are made of Lexan which is pretty tough. This thing could push real blades but what would be the point. It weighs enough as it is. Thanks for the comments. It is getting very close to completion.
Hey Ofak, I used parts from model ships. The scale is to tiny the pieces are hard to figure what they are from. I guess if you build model ships you would know. I figuring people who like pred stuff probably don't build model ships.
