Thanks for all the comments. The bare frame weighs 4.7 lbs. The material we are using is 4"x4". It's 3/32" thick. AndyMark website tells me each transmission is 3.6 pounds, so what you see in the picture is a total of 11.9 lbs.

Dan, yes you have a very good idea of what it will look like, but we have changed the design a lot since you have seen it. =)
