Brief Description: Lateral battery security
|
|
The battery hold-down design works by clamping the battery from the top. I decided that the lateral movement was not probable but also not optimal. So I made a spacer to secure the battery on all six sides (four sides plus top and bottom). Since the fuselage had a natural tendency to roll left on the rotisserie, I moved the battery to the far right and fabricated a spacer using a 1/8" angle. The battery ground wire will be too short now, so I will need to make a new one but have the materials, so no big deal. I cut, deburred, primed, and riveted the spacer in place. Since the battery is facing forward, to allow the posts to be on the front side, the battery hold-down channel sits almost directly over the top of the battery posts. To keep the electrons separated, I cut a piece of Delrin sheet to insulate the posts from the hold down. The posts are recessed slightly, but I feel better with that additional insulation.
I do need a way to secure the Delrin, as it is back there by the elevator push rod.
