............between 1/16" - 1/8"max ,more depth for more experienced shapers.Herb
Herb’s shaped a lot, lot more than I have, but my recent epiphany makes me think you should look at the 1/8" to 1/4" cut for your first pass – thickness of the blank permitting: I started out the cautious route and was doing those 1/32” to 1/16” cuts, thinking that nice and small was the way to go… then I got the master shaping video and saw Jim do it. It then dawned on me that doing a million little cuts it far more inaccurate, and most importantly, it makes a smaller ledge to rest the front variable part of the sander on. I tore into my last blank at 1/8” or so, left a big fat ledge that you can’t miss. All of a sudden the whole point of angling your planer made sense – rest it on the ledge, don’t change your depth, perfectly even cut. I plowed all the way to the stringer, in about 4-5 cuts… you could hardly see the lines in between cut paths. I was grinning from ear to ear. Kept my depth the same and did the other side – now I have an even blank, 1/8” thinner. One more pass and I was down to thickness. Next time I’m doing the full cut. …just my experience.
...........You've been around long enough to go deeper,just remember it's much easier to take it off ,than to put it on.Herb
