Spent about 6 weeks away from my plane while I was worked on my hanger. I started renting one from my flying club airport (we own our airport!
https://www.greencastleaeroclub.com/ ). Anyhow...the hanger is 'open', as in it doesn't have any walls, has a roof only. However they allow us to enclose the hanger at our own expense if we want. Another bloke and I decided on getting back-to-back hangers so we could take advantage of each other's walls. He was decidely the brains of the operation while I was the injured mule.
During those weeks we built bifold (opens center to out) doors, leveled the floors, bored the holes in the ground, and dropped 4x6s and 6x6s into the holes that ran all the way to the roof rafters where we securly fastened them. We hung the doors and got his floor concrete poured. We hung headers for my hanger because I'm going to build in a loft above my plane for storage. We had to work pretty hard in order to allow him to snow-bird down to Florida until March. I'll continue to henpeck at mine over the winter. We figure that we'll put up the perlings and sheet metal once he gets back, whence I'll also pour my floors.
Tonight I fastened the first of my loft floor joists (13'x2"x6"). I'll interchange every other one with a 2"x12"x13' I-beam type floor joists and then put down 3/4" tongue-and-groove plywood for flooring.
