Curious, what dimension plank to cut 1 or 2 blanks from (I saw in one of your videos where you cut 2 blanks from 1 plank by laying them out opposite of each other, if the blank and grain direction allows it)? You mentioned 2 & 3/8 maybe 2 & 3/4 thick to allow shrinkage, but how wide and long. Also, what minimum log diameter would you look for, hoping to get a few planks from the sapwood. Sketching out I was thinking at least 15" top diameter inside bark might yield 4 planks sap and a cant of heartwood (and firewood slabs).
(P.S. watch for a nice walnut SMR blank, I plan to order end of the month.)
