I've seen another thing somewhere that air should be about 18%. I just got done stacking two cords and I can't believe that 33% is air, but I stacked it pretty tight. Maybe some commercial guys stack it much looser.I see this figure thrown around a lot and folks tend to believe it. After all, it is on the Internet and some well established folks printed it. I do not believe it for sure! While it is true that the figure could be right for some stacks, I would question that as an average. For a stack of wood to be 1/3 air, that would mean either some very poor stacking or else stacking loosely so that air can circulate to dry faster. Yes, I have some stacks that may meet this figure but certainly not all of them. If someone said 20%, then I might be inclined to believe that more than 33% air. But then, maybe it is hot air?!
The last two cords I got were from some folks doing some clearing on their land. They knew what a cord should measure, but never measured it before putting in their pickup. I had a nice 4 x 8 squared-up place for them and the first load came up only 3' - 4" high. The mom had a little discussion with the son and made up for it next load, plus stacked it for me and split it down more. I think it was more like 20% air, too. They're bringing me more tomorrow. Nice people but just weren't careful. That was green alder for $120 delivered. If it had been fir, it would probably have been worth more like $145.
The two cords before that were from a guy who was prepared and diligent and had full cords of mixed alder/fir/maple delivered (not stacked) for $135 I think but he has no more. The commercial guys seem to be around $175.
I'll weigh in here Sprinter.
I've had 2 log loads delivered since we started this woodburning thing. Both loads quoted as 20 cord (1st one I split with my brother), and both came out almost exactly that after c/s/s.
1st load was $1300 and 2nd was 1500 about 1.5 years later (fuel went up).
After all was said and done, each cord probably cost me about $80. This was over 95% oak.
Over $140 for logs is pretty steep (here), but what are c/s/d cord going for? I can get c/s/d oak for about $165, so logs are less than 1/2. I may buy some c/s/d next year just 'cause.
I'm going to keep trying to find a log load for a reasonable price. $143/cord for green logs seems a bit rich around here. He seemed unsure about the 7 cords though and maybe he wasn't the right guy to be talking to. I still like the idea, although I don't think I'd do it to save money. Mostly for convenience and fun.
