Todd, Studying your holz hausen, the one in the photo(s) I posted in the Perfect Picture area, the instructions on the chimney sweep site, and the one in the old Mother Earth news, there are some differences I'd like to resolve before I try to build mine. All but one seem to agree on the bottom perimeter being a circle of splits placed on the ground. One uses bricks to elevate the wood off the ground. Not a bad idea. I think I'll price some bricks at the evil big box store. The Mother Earth news people used what they called 'stringers'. Little pieces of kindling between each course (row) the same way the perimeter was created using splits. They say this is to keep the splits tilting downward at the center. This seems to really reduce the density of splits in the Mother Earth holz hausen. And seems like a lot of extra, and perhaps unnecessary, effort to create kindling pieces (in my case), and carefully include them with each course of splits, taking a lot more time and tedium. Did you employ stringers between courses in your holz hausen?
