As a part of learning process, I am thinking about brazing a frame for bicycle trailer, with standard cheap steel non bicycle tubes. I was wondering how difficult is to make a joint type where one tube goes completely through hole in bigger one, like for instance in this stem (although theirs is not brazed, but I think I saw such brazed joints elsewhere)
- What is a strength of such joint?
- Are there some restriction in dimensions, like min ratio of tube diameters, or tube wall thickess? I was thinking of 0.5 to 1.0 mm thick tubes where smaller one (which goes through hole) would be 12mm in diameter and bigger one 24mm
- What should be the dimension of the drill in the bigger one, exactly the diameter of smaller one?
- Brass or silver?
