Any suggestions carl? Im open too them. I based this jig off a pic i saw that stellar machine had but there's was made from aluminum. I kept universal as long as its a 40mm carrier. The front pivot mounts are removable just incase i get tired of zilla's im gonna start on my arched ladderbar swinger. Any recommendations on tuning size? I kicked around 3/4 want it light but strong. I have a bunch of 3/4 .058 wall. Might go with 3/4 .075 wall for the main tubes and the .058 wall for bracing.
