On the other hand, I finally completed a basetube boom camera mount I'd been thinking of building for the last year or so. The mount consists of a wheel bracket from my Wills Wing faired aluminum basetube wheel kit I'd purchased some time ago but no longer use while flying. By flipping the right side wheel bracket upside down and placing it on the left side of the basetube, I now have a very lightweight and pretty clean looking base from which to mount my camera boom extension. The basetube side bracket screw holes line up perfectly with the wheel bracket.
Right side wheel bracket rolled over and placed on left side of basetube...The goal was to not butcher the bracket simply to create the basetube boom mount, so I utilized what the bracket had to offer and machined the boom mount extension around the bracket's existing layout and hardware...
Here I've cut a hole in the boom extension such to fit snugly over the wheel bracket's machined threaded insert...The boom extension is light weight 3/4" thin-wall aluminum tubing...After I was happy with how the boom extension fit the bracket, I worked on the boom extension's two anchor points.
The two pictures above show how I've used the existing wheel mount allen bolt to secure the boom extension. I can get the boom extension nice and snug with no crushing of the aluminum tubing whatsoever. I've also included a secondary screw and locking nut to prevent upward or downward movement during flight. I built both long and short boom extensions to give me a few options to play with while taking aerial photographs and video. The PVC Shedule 40 45 & 90 degree sweeps also allow me to vary my boom mount layout, as well.
This particular basetube camera boom extension is extremely lightweight and durable. With my lightweight GoPro camera system, I anticipate no need to worry about counter weighting and such.
Finished product sans GoPro camera system...
