Title: Hickory stave injury - updated with tiller check
Post by: Kidder on January 07, 2022, 05:12:51 pm
So I’m working on a hickory stave bow. My only experience with hickory has been in board form. The stave looked great but as I’ve thinned the limb down the back of a knot has been exposed with dead wood as has what appears an old injury. There is a little streaming with the grain in both directions. It almost looks like old bug damage that the tree grew around. The back is pristine but I doubt I can get through it on the belly when final tillered. How much of a problem will this pose?

Where I am, it's easy to get hickory. I'd use that for smoking meat. At my age, I'd rather waste my time some other way.

Hickory is 1000 miles plus for me…

Where is it at on the limb ( fade, mid limb, etc) ? How long is the bow going to be?

Yeah, same problem here.  You must be in my neighborhood.  Where on the limb is the damage going to lie?  In my vast experience (I've done six bows, and only two of them broke!), well, I'll leave the opinions for someone who actually knows what they're talking about   ;D  Good luck.

Great question guys - it’s about 5 inches from the fade and fortunately in the widest part of the bow. Low stress design 68 on TTT pulling 26 inches on a stiff handle. I got to thinking about bows with holes in the limb and realized this may not be a whole lot different. So I dug out any soft spots and filled with sawdust and CA. I’ll leave it stiff there and see what I can make of it. FYI I’m in Spokane WA so I doubt there is a hickory tree to be had within a days drive…

Kidder, do you have that bending yet? Looks thin enough to be bending in the pic but it is hard to tell. I imagine that a lot of that is going to go away while tillering. What I am going to say may or may not be popular, but I would leave the damaged areas stiffer than the rest as it does not appear that you have enough meat on either side of the wound to compensate and get it bending evenly. Not completely unbending, but less of a bending radius than the rest of the limb. Hickory is double tough stuff and I think you can work around it. Tiller wouldn’t be perfect but hickory forgives mistakes like a loving mother. I don’t know how much if any the ca/ dust is going to help it to hold up right there. Tough place to have a flaw, but I bet you can get a bow from it.

It’s just barely bending. I wouldn’t call it floor tillered yet. I agree with you and intend to leave that area a little stiffer.

I had a hickory board bow with a smaller but similar appearing fault in it. I babied the thing into a 45 lb bow and it promptly failed in that area. I'm a firm believer in giving it a try, though.

Just clean out the crud as it seems you have done and leave that area a little stiff, it should be fine, you not going to get the prefect tiller like a glass bow that it seems everyone is looking for, but I have done many like that and they will shoot just fine. Good luck.  :)

I agree with Morgan. You've got nothing to loose but some time. I also agree a lot of the bad may disappear. Post your progress and maybe we'll all learn a little.

Kidder, WB,
I plan to make it back to MoJam this summer, you might be able to sweet talk me into trying to score some hickory staves,  and relay them out west!  I am about a hard day's drive from WB, and he is about the same from Spokane, well, maybe 2 days! (lol)

Yeah, I'm a good ways from Spokane, and it looks like this summer's road trip will be taking us the other direction.  I'm kind of psyching up to try out some chokecherry and/or juniper for my next project, so maybe I won't be needing those imported hickory staves anymore!  Sure is fun to work with though.

I’d be all for a relay race of staves west, a road trip, or whatever else seems reasonable in the dead of winter and ridiculous by the time the hour rolls around!

And I will certainly be carrying on with it. Some of the nicest bows started as failures and finished with success.

So I haven’t given up on this bow yet. Chased a lot of problems in the belly, but overall I’m as concerned about the belly issues as I was. Gave it a good heat treat and induced some reflex. Got it to brace, made of couple adjustments to even up the bend and rebraced it and a splinter popped on the back. Except it wasn’t what I would have expected. It was basically the cambium popped off in a swirl around a knot and appears to have taken a little wood with it - but it followed the cambium perfectly. There is a little bit of an edge to it in one spot. Of course it’s in the same location as the belly problem. My thought is to use a goose neck scraper and sand paper and smooth it out. Thoughts? Time to give up?

Is that the stave I mailed? I’ve had a lot of cambium on hickory pop up like that, it’s not big deal at all, I just sanded it down. But that belly doesn’t look great from the photo. I’d be curious to see where it lays in an overall photo

Yep. The belly issue is in the heavily heat treated area in the picture - 7 inches from the handle and 4 inches from the fade. It’s not nearly as dark in person as it is in the picture though. Tough spot for a problem…

Ok so here is where I am with it. I’d like some opinions on the tiller. To my eyes it looks like it’s not bending enough in the top mid and outer, but the reflex in that area is greater so I *think* it’s actually bending more than it looks. The dark area is the problem area, where I of course managed to put a hinge on it early on. It’s more or less a straight taper from the fades. Input please.
