Wha' da ya know? It's raining! Boy, we really needed that!!!

Isaac, Ian, and Joe built and set the front kitchen window frame while waiting inside behind the tarp for the monsoon to end.
Building our sun-tempered cordwood home






Rain be damned---we are laying cordwood! And very glad that we decided to build a timber frame with cordwood infilling, rather than building load-bearing cordwood, because we have a roof to work under. The folks in the Daycreek forum---particularly Bruce and Nancy---have been most helpful and we have achieved very good LPM (lime-putty mortar) mixes, with the help of some bagged dry sand. When the mix is good, you can feel it and hear it while you're mixing.

We have opted to use lime-putty mortar rather than a Portland cement mix. It is time-tested (the Romans used it) and doesn't have the embodied energy of Portland (cement manufacture produces huge amounts of carbon dioxide). So last week we cracked open some of the 100 bags of Type S builders lime we'd purchased, and hydrated it to make a lime putty, using a recipe from New York cordwood builders extraordinaire Bruce and Nancy: 13.5 gallons of water, 3 50-lb bags of lime, and 1/2 cup of dish soap. This mixture is WORK to mix, even with a paddle mixer attached to a power drill. We covered the putty with a film of water and plastic, and let it sit for a bit more than the required 3 days.
Yesterday we tried our first mortar mix: 2 1/2 parts sand to one part lime putty. However, here in Maine we have had a freakishly wet spring---we had five inches of rain just between June 19 and 21, and it's been raining all month---and our sand, despite our best efforts, is pretty moist.
