I've been selling 12/4 slabs of Maple, Oak, Catalpa, Sycamore, Ash, Rock Elm and Black Walnut since February for $100 per, ranging from 24"-32" in width, upwards of 37.5" ( max width for my Chainsaw Mill ), and 10 feet long. Average prices around here seem to be about $350+ for comparable, but those guys are selling either kiln dried or 3-4 year air dried/barn sticked...so I've been busy. Except for the Rock Elm, everything was cut dead standing, so it was pretty dry to begin with.
Currently running a 42" Oregon bar (drilled for mounting to the sawmill rig ), 10 degree semi chisel Woodland pro chains (3/8", .063 135 drive link) and use a Harbor Freight $39 electric sharpener. Current powerhead is a Husqvarna 268, second owner, with a ported muffler, running 93 octane at a 40:1 mix. I've taken the saw apart, deglazed the cylinder and cleaned/reassembled/rebuilt from the crank up.
I just did an upgrade on a Makita 6401 to an 84cc beast (the Dolmar 7900 big bore), with one of those Nikasil kits. I'm making a custom variable flow porting on the muffler ( need to tune the carb to the higher demand for fuel/air, might as well be able to tune the exhaust as well. Adding random holes, or sticking to the 80% rule doesn't leave any room for fudge ), and once it's broken in, I'll swap it out as the powerhead so I can do a Nikasil big bore upgrade to the Husqvarna essentially making it a 272xp (I think) with a new carb, and a similar custom variable ported muffler.
I've only been milling since February, and never owned a chainsaw prior. Nor rebuilt one. I'm on my 5th rebuild ( priors were Stihl and Poulans ).
Will be moving to South America next year, and setting up a proper mill for lumbers to build the house, forge/kiln and furniture.
