Hello guys....a friend of mine just gave me a piece of yew....it wass a smaal branch, aboute 3-4" diameter.....and he cut it in half, and sendid to me one half...the stave is 71" long....the yew is not verry dense, but im verry happy becose this is my first yew stave that im working on....im verry excited...and i hope i will not ruin it....so this is why i need your help a litte....the stave has aboute 2" of deflex.....u will see it in the pictures....and, the sap wood is 1cm. thick (0.39")..i want to ask u, iff its posibile to straighten the stave with heat gun,,,,,and, im a little worried, that if i leave the saap wood this thick...and start tiller the bow, i will end up with moore saap wood thenn hard wood specialy to mid limb, and tips area....si i would realy need some help on this one....i never worked with yew...so, some advice will realy come in handi....thks alot...here is some pictures...

Akila, You definitely has some possibility with that stave, Though I generally like less sapwood and understand your concerns about it being mostly sapwood on the ends. I'm not sure that you have much leeway to thin it. Yew will heat form very well. Use some lard to help keep it from drying to much while heating. If it is still somewhat green you could probably clamp in a form while it dries.
Because of how narrow it is you are limited on style and I would say an ELB style is what your going to have. That is why thinning the sapwood might not be an option. I'd roll the limbs from about mid limb slightly and a little more towards the tips. Keep in mind that generally 1-2 inch of set is normal so form it past that to settle on what you want.
Yew will tolerate some ring violation and it's near impossible to even see the rings in yew sapwood. You could thin the sapwood slightly toward the tips but only in a very gradual degree. Or thin it and back it.

The stave isn't the best in the world, but Yew is pretty forgiving.
You are right to try and maintain as much heart wood as possible. Don't worry too much about following a growth ring in the sap wood, or the sap heart boundary twisting to 45degrees here and there. As long as there is some sap wood and some heartwood all along the stave you will probabbly ok.
It's all about the difference between theory and pragmatism...you gotta use what you've got.
Even if it doesn't work out, I'm sure you will learn a lot.
Last Yew bow I made was really twisted at one end, looking from one side it was 50% sap, but from the other side it was 1% sap.
Oh, almost forgot, I wouldn't bother straightening it, that bit of deflex will take some of the strain for you and give you a bit of a safety margin.
You can always play about flipping the tips later if you want....If you must straighten it, I'd go for steam rather than dry heat.
Good luck with it.

Thks alot guys....i already straighten the stave.....i have to say that i decided to thinn up a little the saap wood....chasing ofccourse a ring on the back of the stave ;D...it wass a pain, i must say......and today i willl start tillering the bow....i hope i can get a bow from this piece of yew.....probably will end up as a verry light bow....but i will be verry happy iff the bow will hold on together...i must say, the back of the bow, is verry crowned in some places.....probably i will have t make the belly round....to compensate the crowned back....i will keep u guys posted....and iff i finished him, i will post some pictures...thks alot for your help....for straightening, i used heat gun....but i used alot of linsed oil, trying not to scorch the wood,

Hello again....like i promised, whenn the bow is ready i will post some pictures...so...the bow is finaly finished, it wass a real challange trying to keep this bow in one piece....the belly of the bow wass full with cracks....and all the time,,whenn i tried to pull the bow to full draw, the belly of the bow starting to lok like little waves....like it wass going to delaminate.....so...finaly i decided to wrap the bow with hemp in those problematic areas....and thenn, for aspect, i decided to make some little wraps, also with hemp , to give him a moore primitive aspect.....the hemp wass soked in resin.....aniway, the bow is ok now....the cracks looks ok.....and im verry happy, to be the owner of a yew long bow....i know it sounds a little exagerate....but for me its like a dream come true.... i have to say thks again to my friend Ionut, who gave me the stave....thks alot man.. ;)....so here is some pictures....

Here u can see the cracks on the belly....there wass to many cracks, and to be onest, without the hemp wrap, i dont think the bow would have survived...

(http://i185.photobucket.com/albums/x212/Akila_07/P2050353.jpg)

Here is the bow unstrung....remember i told u that the stave had 2" of deflex from the start...i tried to straighten the stave and i managed to make her look straight, but it seams that she like's it how it wass before....and the deflex comes back....

Akila, a great bow! The wrappings remind me of the Germanic Nydam ship bows made of yew. The tiller looks great.

looks great Akila. Great job getting a nice bow out of that cracked stick. Tiller looks real nice to me :)
-
Impressive save of a cracking stave!
-
Very cool bow and the tiller is perfect!!! 8)

Congratulations Akila, That came out very well and I'm glad you were able to pull it off. Bow making is always a balancing act of problem solving and I would say that you aced the test. Tiller looks great and the hep wraps just add that much more character. Great job.
-
good job, man...i see why you put the hemp wrapping on, too: those long belly cracks are scary! ah, yew...
-
Very nice,good looking bow from a very challengeing stave. :) Tiller looks great. :)

That's just awesome! Love the tiller. :) Jawge

Good Gravy,
Man takes a bent broken stick and turns it into a work of art. I once more stand in awe at the craftsmanship that is exhibited on this site.
Akila, You said that bow was a dream come true. Well let me tell you that if one measure of a man is how fervently and lovingly he is willing to pursue a dream, you sir are a giant. Beautiful bow and you should be very pleased.

HI....i wanna thk. u all for all the kind words....but i dont know...it makes me feel a little strange...i dont think at my self being a giant....well...iff u consider that im 6,2 feet tall thenn maybe i am....but seriose.....im just a passionate guy...who realy loves making bow's, and i realy have a big respect for wood.....so i think that iff i cut a tree from the forest, thenn i should be verry carrefuul , and i should do all the best i can do, so that the cutting of a tree not to be in vain....i realy suffer whenn a bow explode or broke on me....so this is why i always try to do my best ......not all the time things go as i want....but, i try to learn and not to make the same mistake twice....thks again for all your compliments....also critics are verry much apreciated by me...so, iff u ever feel that something could be better on my bow's please tell me....thks alot guys....i did some new pictures with the bow....i wass making some setings to the photo camera....the pictures looks a little better... ;D...here they are...

-
Dude that is such an awesome bow. I really like how you saved it. The tiller looks perfect. :) -josh
-
Oh no! I just noticed you cut the back of the bow at the nocks. That could be a problem. It is a pretty deep cut too. You may want to consider doing an overlay of some sort. I'd hate to see that break at the tips at full draw. Jawge
-
mmmm....i did not cut the back of the bow.....the bow have side noks....its only a side cut thats all.. the grove dosent go to the back also...only lateral grove's.....
(http://i185.photobucket.com/albums/x212/Akila_07/lateral.jpg)
Here is a picture, with the other side of the nok.....u can see the back is not cut......it is made exactly like u will do self nok's on a bow,,,but this one have side nok-s....i hope he will be fine...
-
good job, man...i see why you put the hemp wrapping on, too: those long belly cracks are scary! ah, yew...
Those long black belly marks are possibly the pithy centre of the stave?... in which case it's a brilliant piece of work to make a bow from such as small and dodgy limb.
Nice bow

Yess...its the middle of the stave....it wass a smaal branch....3" diameter..

You did a splendid job turning that challenging piece of wood into such a nice bow. I was worried about the nocks also until I saw they were side nocks - those are really well done.

Hi
Akila, you worked very quickly ... I know that wood has reached Monday .... you already have a good bow made of it ... sorry for those cracks, I hope its not my fault ... anyway, look great with those wraps .... and tiller is excellent .... I am very glad that you make a bow of this wood, I do not think I would be able ...
Glad I could help, although the wood was not even that good ...
I am curious how it would shoot at distance ... I guess for shot on target is very comfortable ...
what to say more .... congratulations ;)
Ionut... :)
-
Thks alot Ionut....it dosent matter, that the wood wass not perfect....im just glad i could save him.....it would have been a shame to waste a piece of yew....specialy whenn it is so dificult to find it in our country ;D...im waiting to see your bow, made from the other half... ;)
-
where are you from, Akila? What kind of yew is it?
-
Radius im from Romania......and its verry rare here...wi have a natural reservation here in romania, but its protected by the law, and u cant go in there and cut yew , so its realy dificult to find a good piece of yew arrounde here.....this is why i wass so happy to save this piece, and to make a bow out of her....
-
Here's a very fine bow that is bookmarked under March Self Bows. Nice job on a yew challenge, Akila!
