Welcome Brian and thanks for sharing your project with us. Several pictures would be nice.
Sounds like you like the work of the project rather than the hamming at the end.
Why not try using the radio before all that additional bonding is complete. You already may have gone far enough.
The pictures would help understand your objective.
You mention mounting on the ladder and bonding the antenna lifter. Does the antenna get lifted when you are parked? If so you don't have to worry about your engine.
Much bonding can be accomplished with strips of solid metal, copper/aluminum, not as much prep as braid and better if there is no movement between the members being bonded, just snip it off the sheet/roll and drill/screw it into place.
Wondering are you setting up mobile or portable. I only operate when parked.
