I recently have had problems with Baltic Birch, 1/8"and 1/4" flaking on the back, especially on fret work cuts. I have not experienced this before. Could it be just bad wood or the wood being effected by temperature in my shop? I do not run the heaters unless I am in the shop during the cold months and now that it has heated up considerably, I run my fans and ac only when I am in the shop.

I could be bad wood and it could be dull blades. You might try a zero clearance insert. As simple as a business card with a hole up to a custom cutout one. Good luck

I use FD-UR blades and change about every 20 minutes, so, I think the dull blade can be ruled out. I have the new Excalibur with all the holes in the table so was thinking maybe I am not keeping it waxed enough and the wood is dragging the holes edges??

I feel it could also be the wood. I have not scrolled much with BB, haven't scrolled much yet period, but I have built several things with BB. Some sheets have had softer wood than others and no matter what I did, I got some tear out. This, for some reason, seems especially true with the thinner sheet, like 1/4" and 1/8".

Cutting anything less than 3/8" thick I always 'stack' cut with a throwaway piece on the bottom.

Stack cutting will give a better cut to the middle pieces, as well I use these magnetic business cards for O clearance, works great and they stay in place.
