*** The results are (finally) in and the winner is Standard Ricks. More details on page 4 of this thread or you can click through to my blog with results and experiment data here *** G'day All, Having accumulated enough wood for a Holz Hausen and having been keen to build one ever since I discovered them a couple of months ago, I plan on commencing my splitting and holz hausen stacking early spring (in the next few weeks - check my location if this doesn't make sense) and I was planning on measuring and determining some differences between a HH and a regular stack. Before I begin though I thought I'd ask and see what everyone would like me to do in the way of measuring and experimenting. My primary reason is to validate or refute the claim it can season wood in 3 months, or up to 8 times faster than a normal stacked row. Here is what I was planning on doing: 1) Build an approx 8' diameter and height HH. Clear and level a spot with good northern exposure (sunny) and decent airflow. Put some treated pine timber down to raise the HH off ground a little (prevent it becoming a snake house). I might get a bit engineery with the platform/base so it will last for years if the HH proves a success and I keep building them. I plan on marking the centre pole every 2 inches / 50mm or so. 2) Split my timber and set aside 36 pieces. The 36 pieces will be 3 different timber types (probably 2 x hardwoods eg bluegum, turpentine or yellow stringy bark and 1 x softwood eg conifer) of 3 different sizes (small eg 1/4 of a 6" round, medium eg 1/4 of 10"-12" round and large eg 1/4 of 16" round) each of 4 pieces. These will go in the bottom, middle and top of the HH at each point of the compass. Each piece will be moisture-meter tested, weighed, measured and recorded after splitting. These measurements will then be used to determine how well each piece in the pile has seasoned over time, and whether pieces on the northern (sunny) side season much faster or negligibly faster, and whether height in the pile makes any difference (eg higher might get more airflow). 3) I hope to find some scrap pieces of pvc pipe to put some additional constant measure pieces into in the HH. This will allow easy removal and re-insertion of constant measure pieces for constant measuring, and I can compare their end progress with the other 36 pieces, to gauge whether the PVC pipe surround has artificially helped or hurt their seasoning (ie extra space around the wood might help season it slightly faster. or not). 4) I have ordered a cheap moisture meter, and a weather station which logs temps/humidity/barometric pressure/rainfall/wind speed and direction to my PC. This will allow me to build an automated Excel spreadsheet to both calculate averages during seasoning and allow others to guesstimate their seasoning progress based on my results. I will log everything in metric but it shouldn't be too hard to convert to imperial 5) I will take weekly pics of the HH and post in the forum thread for "progress" along with some initial measurements. 6) I plan on building 2 small rows of wood, one running east-west and the other north-south, nearby, and placing some pieces in them also measured as above, to use to compare with the HH at the end of the experiment. Any suggestions or requests? I haven't seen any posts here that verify or refute the HH claim to dramatically superior seasoning, and I reckon it's in all of our interests to resolve this. I for one am dirt curious!
