I have used the reversed carbide wood blade on my circular saw but now have a blade for metal in my collection. Cleaner cuts, fifteen bucks, done.
I use PT below the floor and am nervous about having my cordwood in contact with PT shed parts while seasoning. I had a recent thread here, but when BKVP responded he apparently thought I was planning to season and burn PT lumber:
https://www.hearth.com/talk/threads/of-catalytic-stoves-and-pressure-treated-wood-sheds.181316/ Once I had clarified the question both bholler and begreen said PT wood shed parts are OK, but neither one of them can sign a warranty check on my combustor.
@BKVP ?
Two things bug me about a big shed like you envision. One is airflow through the stack if I stack green 10x10x8 feet. Will the green wood in the middle season? The other is rotating stock if I am part way through one bay, one 10x10x8 foot blob at spring melt. If you have 5x10x8 of seasoned wood at the back of one area, and stack green wood in front of it, will the green wood at the front be seasoned in time for you to burn it on the way to getting at that two year old wood at the back? Or will you need to pull the seasoned wood out, put green wood at the back and then restack your seasoned wood in the front? We are in similar enough climates I doubt you would be to this stage if you thought having to move splits three times (instead of once) was a serious possibility.
I do like
@EODMSgt leaving the back open so he can pile green cordwood in the front without restacking.
Up here I am in favor of metal rather than plastic roofing. The plastic panels get really really stiff in cold temps (shatter easily) and need a lot more support for snow load. But the other side of the coin is airflow. If you are giving away direct sun exposure (metal instead of clear plastic roof panels) you will have to have airflow in spades or diamonds to get your fuel dry.
Looking forward to you results. Birdsmouth's are easy (stair nuts for your framing square are cheap) and metal ties aren't that expensive when you only need a few. You will want a handsaw to finish your birdsmouth's so the inside corner is square. On a 10 foot span I would be thinking 2x8 or 2x10 rafters, but I don't know your snow load.
Do your local woods shrink probably 18-20% as they season? How high can you comfortably stack wet green heavy splits repetitively?
