How far, how fast?
StickMark:
Hickory board, with two courses of sinew on back, with a thick center strip, so 2.5 courses of sinew?
NTN is 59", with bendy handle.
1.35/8 " or say a generous 1 and 3/8" handle.
That width stays for about 9.5 ", and then over next 20", tapers to 1/2 inch tips. Stiff tips for last 4" about.
thickness is 0.5" at center gradually changing to 3/8" towards tips.
(back is gently trapped, if that matters for calculations)
sleek:
I'm very sorry, but this works only for self bows. No laminate or sinew. Too many variables, I could never figure that out.
StickMark:
Sleek, how about this simple white oak bow.
White oak board:
60" NTN
4" handle, with 1 and 3/8 " width.
At fades, 1 and 6/8", going 11 ", and then
tapering to 6/8" tips. for that 17"'s.
Bends in handle, slightly, with tips stiff about 4 inches. 4
Thickness:
6/8" at center, gradually thinning to generous 2.5/8", then thicker at tips.
Sleek, I am fascinated by that statement that we underbuild our bows.
superdav95:
Ok so my math may be off. Sorry about that. From center of symmetrical bow. 4.5”+ 12” at 1.75”+ 8” tapered to 1.5” + 3.5” tapered to 1”+ 4” tapered
To .5” at tips.
I’m in process of building this bow aiming for 50lbs at 28” draw. Thanks

So white oak has lots of variation within its species. Up to 23% I went for its average properties and got a draw weight of 45 pounds. How heavy is the bow and what set did it take?
If a bow took set, it was underbuilt unless it has a bad tiller, but even then, it was underbuilt for that tiller profile. So yes, most people underbuild their bows by those standards.
