I know some scroller's frown on this blade. But if all else fails try the Olson "Crown Tooth" blade. It cuts on the up and down stroke and leaves a smooth edge. I have used this blade successfully many times. It is not my go-to blade. But what the heck, give it a try.
"Unique tooth design allows the blade to cut on both the up and down stroke. ... Cuts a little slower for more control, useful in delicate fretwork. Finish is smooth with clean, sharp, splinter-free edges in hard/soft wood, plywood, plastic and Corian®."
Slow the speed down and also feed a little slower. Olson makes a 2/0 in this style also.
