Charlie,
Nice looking set-up you have there. I an envious of the saw mill of yours. Out here in California, getting enough land with trees to mill is tough. You would need to be in high elevation snow country to get sufficient trees to mill. I did buy a roto-tiller from someone who did build their house from trees milled on their property. Something I would have loved to do in my younger days. For every days work, it takes two to recuperate.
