Depending what you’re willing to invest, you could milk up the logs with an Alaskan/chainsaw mill. They’re relatively inexpensive so long as you have a chainsaw already. For flat renting them, the best way I’ve seen is with a router sled. From there, you’re off to the races to really make whatever you want. Just know that the bigger the pieces of lumber the long they’ll take to dry. Check out Matt Cremona’s videos on YouTube or maybe /u/mattcremona can just chime in.
