Hi there,
long time nothing new and sorry Joe for don't answering your question earlier. About the weight of this assembly, I didn't use a scale but CAD says round about 15.2Kg
I wanna continue with the chains, they are already finished several month ago. Each chainlink is made of 14 parts: a right and left side part, a small tube, a second tube used as a roller, the bolt, the shoe, four screws and four selfmade! 4-sided nuts. The side-parts and the shoes did my buddy Michael, I did all the tubes, bolts and nuts on my lathe (200 bolts, 400 tubes and 800 Nuts). Simply check out the pics!
