the 12" length of 1" SS tubing is notched at 12 degrees to fit a 4" split length of 2" tubing. Each attaches with a pair of #24 hose clamps. The notches (left and right) were cut with a bi-metal holesaw on my drill press, and I lined the inside of the 2" with tape to prevent scratching the paint. Both the 4" and the 12" lengths could be trimmed somewhat and I will probably do so later. |

The assembly is very rigid and vibration is minimal. Our local scrap metal yard sells stainless for $1.40/lb, so this cost next to nothing and probably took half an hour to fabricate once I settled on the design (this is the 3rd prototype). |
If anyone finds the idea worthwhile, feel free to use it.
