Wood issue
Hi all
Im afraid I have a proble with the last batch of wood
It is hard rock maple. when I shave the staves to the final thickness, so far two of them are bending more from the left of limb.
Is it the grain right?
Does somebody have a solution fr this? I thought of soaking it some time in water to relax the tension, but im not sure i understand the problem and dont have a solution...
Thanks all

Outlaw - a photo would help. How much twist or bend? Ten degrees or fifty? Where in the limb? Tips are easier to fix than if the twist starts at the grip. Which Maple species? Some are worked better with wet heat, some with dry heat.
Ken, it is 23.40 h here...jeje,
u got me in my pijama on already...a small drawing though attached...
The left side feels reeeeally like it could use a neck massage, is like if it had a metal slab in it...yesterday while tillering one, it broke in a nice and clean diagonal cut, any ideas how to deal with this./?
Maple is North American, hard rock, ad by the way ive nver seen so many rings before in so few milimeters, maybe this last comment helps...

It sounds to me that you are describing a propeller type twist. I had to bin a similar stave. If this is the case I'd look for another stave with straighter grain.
Yep, propeller it is...
I do not give up. I have soaked it in cold water for some time already, and just bent it in my template...while bending it, it was really difficult, the wood was curly like you said, it was not easy but i placed it as intended.
Im waiting for you Ken, seems you understand woo quite a lot, since seems you had similar issues, im sure u can help out here a bit...
my idea (as commented also by Ken) is that by moisture and heat, can either relax the tension in that direction, or create opposite tension in the complementary growth direction, NOT SURE which one though...
Yes, to some of you this will sound gibberish, useless, unorthodox, and I agree, I fess up I agre! but i gotta know what happens in a need to know basis, so either the output I will post it here for others to know...
It seems that five out of five of the last batch behave like this...

Wood has a tendency to return to the way it wants to be. Much less stress to find a piece which is happy the way you want it to be.
It is much easier to swim downstream than upstream.

i agree with you, but i need to try, ill let you know how it breaks...

tried them all already...5/5 failed
soaked them in water, then placed them over the template for two weeks already...the stave stayed in shape after disattaching it from the template, however, the problem stays ther, less tension, but it doesnt bend symetrically though, quite disapointing, doesnt work an gotta cut more wood now...

Sorry to hear your trials didn't work out so well, Outlaw. The only way, IMHO, to insure "good wood" is not to use the self bowyer's "chase a ring" technique, but to saw the stave into a board which has the growth rings as close to "perfectly quarter sawn" as possible. Like this |||||||, not like this \\\\\\\ more than 45 degrees.
If it broke at angle, it can be due to twisted growth. Then the board/lath was cut across the grain at and the fracture follows the grain and runs at angle through the lath.
You can check for straight growth when you split the wood. When the split runs straight through the trunk or branch you got, then it is ok and you can cut your boards parallel or at 90? to the split.

Ken and Daniel you got that right both
angle, positive, it broke like that...happens to be that the guys who cut he wood didnt realize, and i forgot to ask for that
i got a second batch today, much better, still a twist, but just the tips, and the staves are extra long, so plenty of margin
they are soaking in water waiting to go to my templates
Planning a monghol, a five pieces one, an asirian... lots of work ahead
Thanks for the follow up, I appreciate it!
