This all depends on riser length and how much taper you put into the laminations and Width at fades 62" bow will be quite different than a 64" bow. And is there any reflex or back set. I wouldn't call myself a bowyer. Amateur bowyer maybe. :) JF

62-64” gentle deflex/reflex 18” riser
2 pcs .050 BoTuff 3 pcs full length black walnut .080 tapered .001/1” 1 pr black walnut .040 parallel(for the belly side of the handle)
This should get you in the ballpark, but it depends, because like Bodymanbowyer said, there are other considerations. Your side and front profiles may be different than mine, cross section, etc. I'd glue it up, and then when you begin to shape the limbs, initially leave them a bit wide and long, then you can shorten or narrow and/or trap them depending on what you need to do to make weight, and adjustments to stack height can be made on succeeding bows.

Identify the type of longbow you want to build first. That will help you determine what your finished limb width will be.

23"riser, total stack height of.300, 1 5/8" wide at the fades with a straight taper to 5/8" nocks. Use 1 .080 lamination on the belly and 2 .060 laminations on the back with .050 glass each side.
