That looks great. I was up at the family farm this weekend and went around looking for old wood. There is some really great stuff up there. I was talking about using some of the wood to make my all wood flatbed and my wife and mother in law looked at me like I was crazy. They just don't get it.
I need to get back up there and pull wood out of the hiding holes. I will need to take some pictures and get some advice from you wood experts. My nephew also showed me an approximately 4' by 8' board. It was cut using a 1929 Cat 60 driving the sawmill. My nephew wants to make a table out of it someday. It's been drying in the barn tacked up against a wall to keep it straight for a good 15 years or so.
