I was praying my cordless drill didn't die before I was finished. I think I am going to invest in an old fashioned brace as a back up for sites where there is no power. I did use a lot of coated exterior deck screws with hex heads mounting this box. A ratchet worked very well to turn turn the hex head screws in and conserved the battery in my cordless drill.......
I won't build any boxes this big on the ground again........my thinking was it would be easier to construct it entirely on the ground but at 130ibs it was too heavy and awkward to wrestle around with. Building one this size in components then carrying them up one at a time is much easier and safer....the only thing about that is there is lots of screws to drive which means a need for 2 or 3 battery packs or power to recharge them.....
Here is a link to a bat house I built last year from 8 components almost as big as this one. I'm guessing it weighs close to 100lbs.
