Saturday I sheathed all of the walls. Working alone required 3 times the effort but I am very pleased with the outcome. In order to do this, I screwed a 2X4 to the bottom of the floor joist so that ½ of it was exposed past the side, creating a ledge that I could set the 5/8” exterior T1-11 plywood. To keep it from tipping forward, I also screwed another 2X4 to the roof rafters about 2” from the walls. This way I could lift a sheet into place by slotting it up between the wall and the roof rafter 2X4, then push the bottom in until I could rest it on the ledge. Then I could work hands free to screw each sheet into place.
Each sheet required the following:
- Move the ladder into position, climb up the ladder and take measurements (making sure to get the correct angles for the 9* pitch of the shed roof)
- Get a 4’X8’ - 5/8” sheet of plywood from the shed and carry it to the sawhorses and cut each sheet to the exact measurement for it’s location.
- Carry the sheet to the ladder and climb the ladder backwards until I could just grab the sheet by the top outside corners, then jerk the sheet up 6” at a time until I could rest it on my feet. Rest a couple of minutes, then press the sheet into place and get it positioned perfectly.
- Once I got each sheet into place, I tacked it to the studs with 4 screws, climbed down the ladder and up into the treehouse to mark the window or door locations.
- After I got the windows marked exactly, then… down the slide, back up the ladder, unscrew the 4 tack screws, remove the plywood sheet, lower it down the ladder, carry it to the sawhorses, cut the window opening, carry it back to the ladder, heave it back into place and permanently screw it into place.
- Repeat 10 times…
Sunday, I was so stiff and sore I didn’t get much done.
