Hey guys. I goin to make a battery tray for my sundowner that will be further back in the fuselage. I planned on hardening th e stringers first with some thinned epoxy. Then place a hardwood square runner on top of the stringer on both sides. Then adda tray between the stringers for the batt to mount on. Final step another hardwood runner epoxied in on top sandwiching tray between them. Think thst sounds like a plan?

Thanks,
Erik
