radial tubes and 0.875 radius connectors in the side radial tubes, temporarily hold them in
place with tape. Lay the entire assembly over the layout surface with hoop tubes in place. Use
a box or an object about 9 7/8” tall to hold up the bottom of center section. Line up the radial
tubes with connectors on top of the hoop sections where they meet the 60 degree lines.
Making sure all joints are tight on both ends of the radial tubes, check to make sure the side
radial tubes are straight above the lines on the surface. Also be sure the bottom of the center
section is centered, and remains centered throughout the rest of the build. Use a framing
square to check from the surface up to the center section. Use concrete blocks or build a
wood frame to hold it in position from side to side. Let the radial tubes determine the height.

Now be sure the two lower hoop sections are in place on the surface with the 21 inch
chromoly tube floating between them (inserted but not permanently connected) with the
lower ends of the lower hoop sections at the Outside edge of diagonal brace line.
