The exit holes for the zip ties were surprisingly easier to drill than the entrance holes. The cutout for the stick was best chomped out with a nice diagonal/wire cutter after a single access hole. Though it left sharp places I didn’t like, there’s just enough of the free end of the ties to grab with a pliers if they need tightening. That was a tough call. There’s a chunk of closed cell foam from pipe insulation inside to spread the force of the end of the stick. The hardest part was digging thru the collection of old broomsticks to select ones that provided proper chromatic bracketing of the ball color.
The whole thing, including the writeup took just under an hour. Sometimes things go smoothly.
