The arm is made from either .040 or .050 aluminum sheet (I forget which but it is incredibly thin) formed into C channels. Two C channels are placed over each other and "buttoned up" with aluminum rivets. Anyhow, it came out incredibly light and very strong. We did this because box tubing that large with that thin of a wall is just not available.

Each "joint" is made from 1/2" aluminum plate, pocketed out to leave only 1/8" of thickness where material is not needed.
