A few pictures from this morning....
Took the glued up blank from the form and centered a string on each end. Marked under the string at center of the bow.
With a true straight edge I drew a line down the length of the limb on center.
Marked the ends of the riser.
Measuring from the centerline I marked the width of the bow at the fade out... 1 1/8" wide.
From the center of the bow I measured 33" and marked the nock location... added an inch to bow tip.
Again from center line I measured 3/4" at the nock.
Connected the lines at the handle and at the nocks for the limb profile and ground away to the lines.... I gave up on sawing the bow out a long time ago. Fiberglass eats bandsaw blades and grinding is fast and easy.
Here is the roughed out bow strung with the tiller string. Limbs bending within 1/8" of each other at this stage and plenty of weight to work with.
