Bow Testing 2023 / 2025
simk:
found pics from the bloodwood build on the phone - that was probably from the start of the tillering process - the limbs pull straight later at fd.

Willie: The laminated boloodwood semi-recurve had a similar profile like pics 1 & 2 - just less deflex
The laminated yew maple bamboo was a classic asl longbow, 66"

so not much deflex needed to place high on the list?
Was there any deflex out of the handle with the clasic ASL?
simk:
wiellie: I glue these up with no deflex but i think they are on the edge. a lot of strain on the inners. but beautyful shooters. They are very light in mass, 400-450gramms. narrow like 34mm. but it only works with the very best material - and bloodwood is pretty stubborn at taking set. then rather chrysals away spontaneously. as you see the osage took plenty set. it probably shows what would have been be the best amount of deflex for the glueup. you can put more and more reflex into a wooden bow but they always settle in to where they want - at least with me. I would suggest glueing in a little deflex. Probably should make one new slightly deflexed caul for me as well. A little deflex out of the grip is always a + I'd say. It also allows you to make the bow a little shorter than straight bow. The asl is straight out of the grip. maybe the tapered powerlam makes it looks a little deflex.

Very interesting find! Why is that? Why would a hickory back be a poor choice? Does it take tension set (assuming that’s even possible)?

lots of different kinds of hickory here in the US, and densities vary widely. Lumber grading is mostly by appearance rather than structural strength. https://www.extension.purdue.edu/extmedia/FNR/FNR-285-W.pdf
A bowyer sourcing top end hickory in the states would most likely not source from the lumber retailers.
