Ben, those big logs are 36 inches long. That's because of how they grew and what I was allowed to take. I got as many 36 inch pieces as I could. Some will be for lams and others will be for risers. I did get one beaut that was 64 inches long.
The 36 inch ones will be split with a wedge till I get them down closer to an extra large Osage stave size. Then I put a 3/4" X 3 tpi blade on my bandsaw and square them up and then I cut billet boards from there on. I try to get as many 1/4 sawn pieces as I can, then as many rift sawn as I can. Then if possible I'll cut some riser blocks out of it. Osage is like gold and I don't want to waste any of it. But for the first year they will just be split with the wedge and left to dry.
