I put the roof on after the shed was full of wood so for the most part I was standing on the wood and not on the roof. I could reach across the 3 foot section of roof as needed. If I did need to put weight on the roof I was careful to be kneeling or standing over the rafter. The rafters would bend but only a little because of the stacked wood under them. I chose to run the rafters so they would line up with the peaks as opposed to the flat part of the roof sheet, every 18 inches. I think you can see that in some of the pictures. I plan to add some purlins and possibly some more support mid rafter as the shed is emptied. Yep, I squared off the ends of the posts with the chainsaw. Unless you are driving the oz post into loamy rock free soil they don't go in without twisting, and if you hit a big enough rock they will veer off vertical. I think all of mine twisted, but I got lucky and only 2 of the 12 I used went off vertical badly enough that I had to dig them out and remove the rock that caused the problem. The twisting doesn't really matter if you are using a round post, but would suck to deal with if using a 4x4. One thing I would have done differently is; I would have added a notch in the post for the horizontal members to sit into. You would want to do the notching after the oz post had been driven in and the post fit into the square opening. Have you ever watched that "reality" show "Life Below Zero"? The guy who is a hunting guide, Eric I think his name is had a similar woodshed at his cabin.
Yep, lag screws in some places and star drive wood screws in others like these http://www.amazon.com/The-Hillman-Group-41948-Outdoor/dp/B000BQWYN4 I am not not a tradesman, and this was by far the biggest construction project I've ever tackled. I would not be offended and would actually love to hear from some of you guys whom I'm sure know way better than me any tips or pointers on a different or better way to do anything.
That shed is freakin awesome, I had ideas of building one with wood like that because it looks good and I'm cheap. But it's easier to ride one mile down the road to the lumber yard than cutting all those small trees so I'm going the conventional route.
Inspiring for me. I have a tree plantation that needs to be thinned in the next few years so I will be cutting lots of small trees. Now I have a project to use them on instead of just cutting little rounds to burn as is.
