Bows / Re: The best shape for a reflexed bow?
« Last post by simk on Today at 04:01:16 am »Toumo, in an earlier post you asked about how to measure string angle?
This is what I would suggest.....
With a recurve you measure where the string touches the limb - measuring some kind of tangent does not make sense because the angle would stay the same (0) all the time.
At the end of the day we don't actually have to measure anything. Its enough if we understand the concept and know the general guidelines to keep the angle low.
cheers

Bows / Re: yew - a madam's target bow 31# -27"
« Last post by simk on Today at 03:08:23 am »thanks guys! this is basically the bow and design you will find in the books and howto's of the early past century - it was the the early days of the asl. its described like that by howard hill and others...and they also suggested hornnocks like that. At that time it was the logic further development of the victorian longbow which was the dominant design up to then - see e.g. Saxton Pope.
I like this design very much.
Tuomo, its somewhat 66" ntn. the dark area? probably you mean that brown rest of bark? ....this stave didn't ask for sap-reduction - it therefore still shows some remaments of bark and bast.
cheers

No suprise that Simk finds bamboo to out perform hickory, although saying

always perform poor. Its a massive differencemakes me think there is better moe hickory to be had, or a different thicknesses to better match the very dense bellywoods. Maybe Simk can say more about what he worked with.
