I’m gonna guess around 2 1/4 cords once I get a roof on. But that won’t be till after Christmas at the earliest
As Long as you put a couple of long stringers all the way across at various heights it should stay upright.
That looks great! I'd love to do one of those, except I need to take a break from hoarding, and once I got started I'd be obsessive compulsive and have to finish till I drop.
It can be kind of a pain to do, but if you put those splits in the center upright they will act like a "chimney". One of the advantages of a holz hausen is the wind will always hit the outside of the stack at a 90, flow into the center and up out the top.
I think if you just focus on maintaining the downward angle you won't have any issues. I've got 22 stacks and they are all fine. I've posted before when I didn't do a good job on maintaining the angle on a few of the stacks that were built on sloped ground but I fixed them. Sometimes you just need to step back a few feet to see the angles.
We have been using these for years with mixed success. Lately my wife has taken to building them, and while of course that is great (!!!) they do not have enough angle in the outer ring to be structurally sound. We typically have two blow out a year, rarely just from the entire thing swelling at the top but mostly due to high winds during storms. Not being critical and absolutely with all due respect to you but to my eye your hausen looks to be a bit too flat in the outer ring and combined with the slight widening at the top it looks just like the ones that blow out on us. The key seems to be a lot of angle on the outer ring, say 30 degrees or so and a slight taper in the outer diameter toward the top. This all applies to one outer ring with the center filled up with splits thrown in loose. If you stack the interior splits straight up and down, or standing on one end, the hausens end up with a lot less pressure on the outer ring and are far less likely to blow out. We tend to build them about 7 or 8 feet in dia. at the base, with a slight taper moving up and only about 5 or maybe 5 1/2 feet tall. The entire reason for these smaller hausens is that it is easier to restack them every time that is required. If you throw a tarp over the hausen and wind a load binder around the tarp about 12" to 24" from the top, I do not believe they will blow out. Also this will keep leaves and other debris out of the hausen as well as rain. That said, we do not cover ours because my wife does not think it is nessasary and as she in the one who re-stacks them, who am I to argue about it?
Well the formula for the area of a cylinder is A=2*3.14*r(r+h) where r=radius and h= height. I didn’t see where you said what the diameter or radius of your HH were, so say it’s a theoretical 4 foot radius and you said 6 foot height… your area would = 251.2 cubic feet divide that by 128 cubic feet in a full cord = just shy of 2 cord. Adjust the radius to match your actual and you’ll have a pretty gooder approximation.
That's not correct. Cylinder formula is pi * r * r * h. Which is just the area of a circle times the height of the cylinder. 4 ft radius and 6 ft height would make it 3.14 * 4 * 4 * 6 = 301 cu ft. of volume not area = 2.35 cord. Take away the slight loss from angling towards the center as you go up and you are just over 2 cord.
Because most of a holz hausen is loose piled rather than stacked, the usual cord volume of 128 cu. ft. really does not apply. The loose pile size that seems to be pretty much the one used is 180 cu. ft. to make a cord. So the volume of a holz hausen with a loose piled center is closer to 180 than 128 cu. ft. A reasonable 'guesstimate' would be something like 160 or 165 cu. ft., or of course the outer ring can be calculated and then the inner loose splits separately then added. But honestly doing more exacting calculations on inputs that are either rules of thumb or outright guesses seems a bit off to me. The formula for a cylinder is pi * r * r * h where pi is well, pi (3.14156 etc.) r is the radius of the hausen and h is the height of the hausen, all measured in feet if you want the answer to be in cubic feet. As they say, 'Measure with micrometers, mark it with a crayon, cut it with an axe..... tolerances add up'.
I think you’re right. I miss rememberd. Mines for the surface area of a cylinder. High school math was a long time ago.
Same way all that Boolean algebra got involved in the computer you typed that question on. It just kinda' happens....
Some people get very particular (i.e. anal) with their stacking so while it's not as tight as a traditional stack, it can be very close. But it all depends on your split size and your stacking abilities. I try to stack my insides somewhat neatly but not level 9000 neat. I used to have lots of shorties but now I've raised my standards and don't take shorties for the most part so the inner splits are the same as the outer splits. You're starting to sound like Roger Clemens there with the "mis-remembering" hahahaha. Yeah, 2 * pi * r = circumference of a circle whereas pi * r * r = area. And surface area of a cylinder would be twice the area of the circle (so 2 * pi * r * r) plus the circumference * height = 2 * pi * r * h which is what you posted originally = 2 * pi * r * (r + h). I once gave a presentation in bacteriology class on using a bacterial protein (bacteriorhodopsin) which has a base state and an excited state (p-p-pi bonds get zapped with the right wavelength of light = right amount of energy and double bonds then act like a single bond) and thus you can use them to store information in computers. Nobody, including the professor, knew what I was talking about when I started counting in binary - 0, 1, 10, 11, 100, 101, 110, 111, etc. I ended up writing my thesis on this subject.
And there’s something new for me to learn today. No not the formula for the volume of a cylinder/cone but that 180 cubic feet is an unofficial standard measurement for a loose pile of firewood in one cord. Now I know. Sent from my iPhone using Tapatalk
It is something I read a couple of times and just kinda' adopted it. I really do not know if it is accurate but then again, how much accuracy can we apply to a pile of firewood splits? That said, it is the measurement I use when buying firewood; I measure the box the wood comes in (dump truck, trailer) and then guess at the answer As an aside, I have only ever had one seller come close, and that was 120 cu. ft. of stacked splits..... close enough. The others ranged all the way down to just under a half- cord.... not close enough. :-(
My head hurts reading all the math... I am not a number kinda person. The stack looks very nice though!
I’ve always thought it would cause more trouble than good if I learned how to read,…. You just reinforced that notion..
