Blew up your pic Scott....and been staring at it for hours, and then looking at my wet cut burls....
All I can say is Steve was right when he said when it comes to burls "all bets are off"
Can say that burl exposed closest to bark looks the most like "Burl" in W Oak and dries more uniformly.
Burl I cut down the center of pith is pretty for small stuff, but shrinkage on center of cut line is Wildly different, and very prone to cracking.
Most stable cuts were at 90 degrees to tree growth(and probably how I'll cut my last 13" burl.."Cookie" fashion using the "fissures" as my cut line).
BUT none my stuff approached that size! Take a look at the shrinkage pic in 11 months in the house. Not sure about a full length log slab.
Notice how the bark side 100% burl skim stay virtually flat as it dried!
Be interested in what your Woodmizer guy says.
Why do you think I asked for advice
Hope pics are of some help,but you're kinda on your own friend!
(BIG help..Huh?)
