And one final set of shots that show the pipe mount and the Teflon PTFE coupler. A simple O-ring is fitted around the ears of the U and over and around the the pipe. The U is mounted on a Lord type soft mount. The set-up has proven ultra reliable, over many many seasons of flying. Inspired by the Hush Clamp that Dave Von Linsowe designed 20 years ago or more

If you look closely you can see the 4-40 button head screw under the Teflon, as suggested by Ed Skorepa
