Hello Brother Jim, I have harvested all my own timber for my barn 24x42 and the savings at the saw mill is 2/3, but this does not include the cost of a new chain saw, logging chains, home made log movers, a peavy handle, gas for the 18' rack truck, countless hours, and things that I may have forgoten. When all is said and done I think I have saved at least 1/2, not including my labor.I have two years invested In the planing, design, and cutting my frame. I think when finished it will be worth every hour and drop of sweat invested, so all you experts keep the help and advice coming, Thanks, John..
