What does one look for to spot a stressed log where the check will grow and split the board as it is being sawn?  One where trying to saw around outside first, beyond the check, isn't a good idea?   Mr. Magic your 31" cherry above must have been pretty stable.

Another way you can do it is to put the check on a 45 degree angle from the blade and keep the check on the corner the board that way you can trim the defect out of every board. This works best if you have hyd. to turn the log and a edger to trim the little bit of check off of the side of the board. Not every board will have check in it but you can remove it from the log and the lumber this way.

I think I would have put the check at 45 degrees.  The value in cherry is flat sawn high grade boards and your not gonna get many with the check vertical/horizontal.  Grade sawing that cherry would have taken a lot more time...always a choice.

Stable and very old.  That old gal was over 300 years.

In the above logs and with most Cherry and Walnut, 45° sawing will greatly reduce the number of 12" board that come from the log.

The amount of defect is the same in the log no matter how you saw it.  You can't change that.  Decisions have to be made with each log sawed; where do you want that defect to appear in your lumber, what dimension lumber do you want, what does the customer want.

The majority of my customers want the maximum number of wide boards, hence the reason for orienting the log as illustrated above.

Not saying what you did was wrong MM just giving another option on the check that was in pic. The rest of the log and the customer desires must always be taken into consideration.

I saw end-checked logs, especially Black Cherry the same way as MM.

My opening cut will have the check parallel with the blade or at 90°, and I will open all 4 sides, but the boards will come off the cant when the check is parallel with the blade.
That will leave the defect in 1 or 2 boards in the middle of the cant.

As MM said, most customers want "wide" cherry lumber.

well thanks to all for the ADDvice! These logs are green and the check damage isn't severe but a 4" split up could be a 4" to the 10th later.  We'll get it better right next weekend!  MM that is dastardly check you show. I was adding up the boards you saved thinking  "that's why they keep calling him back" YOU THE MAN!

Oh, I don't think that either of us were being augmentative.  New sawyers and us old folks too, need different perspectives on log set up proceedures.  I'll try to do some pictures sawing a log with a severe surface defect or a big old knot turned to the 45° position.  At times, that is the absolute best way to set up. 

I had several "opportunities" today sawing some big old butt flair Cypress.  It didn't have any heart check, but it did present some challenges.  One butt was 34" and the other was 38".  They were about 130 years old.

I hope to finish the Cypress tomorrow and start on the White Oak.  Looks like he also may have a few more Cherry and Sassafras logs.  He said a "couple of days".   ::)  I may still be there next week.   :)

At least you didn't have to waste time loading a new log for a while, MM! That's some fun looking wood you have there. The cypresses in my yard are maybe 18-20" and I don't think I ever saw a 31" cherry tree but maybe twice around here, and both were quite curved.

If a customer is standing there and I am cutting his logs I will be just as chintzy as he (or she) wants me to be. I may suggest what is best as far as a split log but let them make the final decision. For myself there are no wasted cuts on a ranch. If it looks like it might make a board of some size I can use then it will be so. If not, it's firewood.
