Somewhere in the dim ages of the past (farther back than last week) I remember reading about (and actually doing) tillering selfbows, two-wood or tri-lams bows by "stock removal" only on the back of the bow. The advantage being that the bow could be kept strung as stock was gently removed, and you didn't have to keep stringing/unstringing/restringing to check the ellipse of the tiller.
Anybody remember this? Can you point me in the right direction for instructions?
