Tom, we're still in he learning mode as far as being a sawer is concerned. This is the first quarter sawing I've done so played it a little cautious. Was afraid the exact middle of the log might have some funny things going on so I cut 3 boards out of the center, one above, one with the pilth in the middle of the board and one below. The center board is true quarter sawn, the ones on either side are so close on a log this large that for all intensive purposes they are quarter sawn. This gave me 2 choices for book matching. Quarter sawing yields more stable lumber, a lot less likely to cup. Important for table tops and I'm hoping for boards this wide. The rest of the log is close to quarter sawn.
I took one of the remaining cants stood it on edge the cut one board above and one below center. Again if I'd taken one out of the center it would be true quarter sawn but one on each side is real close. Now the two cants from this were sawn. I set the saw to cut one inch boards above the bunks, put the cant on the bunks and cut a board, remove board and flip the cant 90 deg, cut a board and repeat till your boards are down to say 3 inches. The further out from center you get the more radial or flat sawn the boards are but still beter than actual flat sawn.
Lets hope a picture is worth a thousand words or about 10 thousand of mine.



Most lumber even oak now is plain sawn just because of the time it takes to quarter saw I guess, but here time isn't worth much.
