Back to the hatch.

With the Dubro hatch latch cutout made I drilled some holes through my modified tank floor for weight savings. I was not concerned about the strength of the structure as it would later be glued to 1/8 inch sheeting, and the tank floor was made from 3/16 inch sheeting. I also had to make a raised "battery floor" to get the battery over the lip created by F1 and the nylon hinge/balsa sandwich. I used 1/8 inch sheeting. I attacked some balsa stick to make some square legs to raise the battery floor high enough to be flush with the F1 lip, made holes in another piece of balsa sheet cut to size for the battery, and glued in the latch with CA. I then glued the whole works together with CA. My intent was to then put some velcro on this battery floor, which I'll get into when I describe installing the "guts." One more point of interest with the battery floor was that I used a square leg in the middle to help with strength of the floor.
