Grain orientation on stave
Ruddy Darter:
I got the sides all shimmy'd up with a bit to spare for shaping and then I'll mark on closer final dimensions for the belly. After that I've decided to take out some of that D-flex at two points. It's also where the stave twists out, it runs straight at the handle for a good while and then twists out again same direction, this is also where the D-flex kicks in, it's pretty straight a good 26" at the centre. The bow will line up bang on then and if I get it moving evenly hopefully more chance of it staying in, so seems a good time to do it, I'll then shape and get ready for tiller.(I gave the stave at press at the centre and gave quite evenly and had a bounce to it, starting to feel a bit bow like :))
Pic shows where I'll heat gun out(going to try and twist a little), pencil and scraper mark the spot.
Another pic of the funky top limb, (still with a little extra wood for final shaping.

FilipT:
So pacific yew is practically only wood that allows messing up grain, taking too much off sap wood and such?
penderbender:
There are some other woods that a grain tolerant too. Yew is just one of the better ones. Cheers- Brendan
Ruddy Darter:
I have know idea to either, it's all a learning curve to me, I'm not sure I'm doing the right by this stave either, just trying to apply my(frequently questionable) logic . I havent removed any sapwood as yet, this is how it came. (If all goes pair shaped with this it's a good bit of practice for a nice straight forward stave I have.) Any pointers always appreciated.

All yew is fine with grain violations, bad tiller, knots, holes, rot etc. It's probably (in my opinion) why it was so used so much for mass production of military bows. You can chop them out of the stave and rough them out quickly and send them off, without needing to spend ages chasing rings, heat straightening and so on. It's no better at being a bow than all the other European woods, it just makes a bow faster.
Pacific yew is especially good at tolerating straight bows being cut out of curved/twisted staves. It also never requires back rings to be chased, whereas sometimes on coarse European yew you need to be more careful.
