if you check the logosol site theres a lot of info on the kit they do for log building, I myself have an M7 mill, with a 660 powering it, along with the log moulder, again powered by another 660, and the things that you can turn out from raw timber with these two bits of kit is amazing. Over here in th UK I have a friend not far from me who started a business building log cabins using the exact same kit, he's now progressed to static sawmill production because he was getting to busy with what he had(took about 14-20 days to saw and mould the timber for a cabin) I only do smaller stuff at the moment, sheds, garden furniture, hot tubs and the like, because i dont have the yard space, but hopefully this will change soon!! Ive been involved building the cabins and with the logosol kit its real easy, 4 passes with the chainsaw, and 2 with the moulder(3 or 4 if you want internal/external profiles) and your log is done, they do moulder knives up to 8" so you can use some really big logs the only down side to logosol kit is the price, but compared to what else is out there the quality and simplicity of use make up for this.
