fittings to a cap fitting having a blind hole socket for the center pole as well as providing any of the stop means discussed above in a preferred embodiment the spoke tubes 16 are also made of a rigid plastic pipe such as u00be inch pvc the associated flexible tube 18 which is used to form the circumference of the wheel like subassembly 26 may be u00be inch polyethylene irrigation pipe which is cut to have a length approximately matching the circumference of the tree the set of fittings 20 used to connect the various tubular members may comprise various mixes of conventional arid modified plumbing fittings such as tees crosses and connectors some of the these fittings may be slip fittings that have socket sizes modified or selected to allow various of the tubes to fit entirely through the fitting rather than being arrested by an internal socket wall or set of threads in one embodiment the fittings that slip about a u00be u2033 pvc central pipe are bored out to an internal diameter of about 1 125 inches and the ones that fit about a u00be u2033 polyethylene pipe have an internal diameter of about one inch although the modified fittings made for a prototype net support were formed by cutting operations on conventional fittings those skilled in the art will recognize that this is an economic decision and that if the market for such supports is large enough one could readily mold the slip fittings a modified cross fitting 30 as depicted in fig2 may have a hole 32 in it perpendicular to.
