Hi Gang. Back from the adventure. It was fun roughing it on the bike. Thanks all for the latest praise. Kind words can be very encouraging.
Dry-bags averaged 15lbs each, so 45-50lbs of weight on the tail.
Pics of the jerry-can mounts will be up tomorrow.
As for the brazing, I used Harris products stay-silve flux, silver brazing wire and mapp gas. The 3'8" steel brake lines, are basically soldered together, with stronger solder, at a higher temperature. This rack job was quick and dirty. Was in a hurry to meet adventure deadlines. I did a really precise job, especially the tube mitering, on a 3-year-build, 1:10th scale R/C scale Class-3 Landcruiser, roll-caged 4x4.
It was a youtube video that showed me how to braze like that. The video basically said, clean your areas with acetone, then flux, the as the temp rose, the flux turned clear right as the steel was starting to get red. Thats when I added the siver braing wire. It's cool to watch as the brasing wire wicks into the joint.
