I was reconsidering a single tube like you said bikejunkie. My intention was to have a cargo area under for the Coleman. I'm sticking to my guns here and maybe :roll: I'll try it on another build sometime. The next part is to fit a curved down tube. I saved two curved pipes from the trash last summer, I think they came from a hammock stand, with the intention of using them on a tall bike.
My house guests left sunday and I'll have more time for The Shadow, that is while I'm showing some progress on a SideWinder for my youngest daughter. My collegian has a taste for the swingbikes and is demanding very politely a custom bike to her specs. I put one together for her sister. It doesn't take to much time to make one and I'll make a slow show of progress with it.
More pics later.............GL
