Thinking about making my own TM mount from some scrap aluminum again, but want it to extend like a birdsail mount. For joining aluminum parts together like this would you weld or braze? Or better yet is welding neccesary, or is brazing ok being it should not flex? If it needs to be welded I'l have to call in a favor, but I can do the brazing at home. The mount will be smoothed and painted after, not polished.
