The cage looks good. My only concern is you diagonal across the main hoop. The bars should be almost touching.
NASA CCR- 15.6.14.B Tube / Mounting Plate Specifications
Any number of tubes may attach to a plate so long as they are touching each other at the plate. There may be
a small gap between tubes to allow welding 360 degrees around each tube. If there is no gap between the
tubes, they must be welded around the base as much as possible to form a single figure-eight weld, AND the
tubes must be welded to each other for two (2) inches up from the base plate.
