| By eye Get the shape correct (left-right as you hold it), then start tapering the ends, keeping to the D profile.
Once it starts to look thinner at the tips put one limb tip on the floor & make like you're stringing it. You only want a couple of inches of movement, but you want to see a nice progressive curve.
Keep whittling & bending until you have a shape, profile & depth, that will make 6" of bend.
Now cut your temporary nocks & use your tiller & an old bow string to do the rest. I did the kids first few bows with a simple tiller, but moved to using a pulley & rope too when the poundage went up. Makes it easier to see the movement on longer bows too.
