Yew Warbows
AH:
I am currently working on a yew war bow, just thought I'd share a few pics with you guys and take some advice. Tiller check, anyone? I'm still at 21" on the tiller, I don't really want to take it any farther until I get my pulley tiller tree set up, that way I won't get as much set and if it explodes, It'll blow on the tree and not while I'm pulling the string down on a tillering stick. this one is 77", made of pacific yew, 40 rings per inch, it's a pretty dense stave. It has go one nasty knot, but it seems sound and I have left a mountain of material around the knot.
I also have another yew war bow stave that I got from Carson at echo archery, but it'll be a while 'till that one gets on the tiller tree.
AH:
thought I'd include some pics of the other stave:
This one is denser than the stave I currently have on the tiller, I can't really count the rings but I think it is around 60 per inch. It's also got a nasty knot which I've left a mountain around, but I'm not done roughing out yet. Thanks, Carson for the awesome stave!
ionicmuffin:
well, id say your left limb the one with the knots needs to bend evenly with the other one, and maybe better not touch the outer part of the right limb. Of course, make sure not to work those knots very much, better to have them stiff and have to correct that than to have it hinging at all the knots, but in general the limbs are imbalanced
WillS:
The right limb looks alright, although it may end up being slightly whip-ended by the time you get to full draw (not necessarily a bad thing for a warbow, as mentioned in TBB3)
Is it possible to see a pic of the knot? Yew can take some crazy violations unlike other woods and you may be playing it a bit too safe!
Del the cat:
+1 for what Iconmuffin said.
Knots are tricky.
IMO they still have to do some work else you are are just overloading the rest of the limb, and they are ok in compression, they just have zero strength in tension as they aren't really connected to the rest of the wood, they are like an unglued plug.
Check check and check again that the back is sound over the knot, if you have a good clean unbroken layer of sapwood you can reduce the belly to match up with the rest of the bow (ok, maybe just a whisker thicker). Check the knots ar sound.. any big knots on the belly that don't appear through onto the back ahould make you ask.. where do they go? If they have grown over, is the wood sound or rotten whener it's grown over.
When I get that situation I pick away at the knot to find out what's going on inside, but DON'T go through and disrupt the sapwood back.
