I searched for 'procut' and it was one of the last threads on page one. Problems is there are so many variables- search for procut, pro-cut, pro cut, chainsaw mill, etc. :biggrinbounce2:
I too have the plans and will soon be building a modified version(need to cut a sliver off several dozen 30' logs to use for rafters on a log house). Haven't found anyone local with that long of a mill, but have most of the parts to do it already.
