Working the Osage Bow Part 6: Heat Bending

- I was forced to shelve the beginning portion of my heat bending videography because of a rush of visitors. This tales up in the middle but still is a good explanation of the process. It is simple, you CAN do it!!!!!

Excellent John very informative, Thankyou..
Thank you. It definitely helps though having a much hotter heat source. I usually use my electric range on high
You make it look so easy. I want to try.
It is, and you should. Some of the more severe bends should be done in stages, and once it is near the apex of it's bend, it could be steamed on the bending form, and more bend put into it.
I think this is where I'm headed with my next bow. My fingers are itching to try it.
You'll get hooked. It's a cool bow design.
Ever thought about a Channel mold a and a hole to the undeside. So you can heat from underneath. i
@@jeremysnead9233 I have not but it's an interesting idea.
Hey John. Just found this old vid of yours. I've got a couple of questions. First, do you find the absence of reflex on a short gullwing can lead to stack? And secondly, how do you find Yew responds to severe bending through dry heat alone? Great channel by the way. Loads of gems here!!
Howdy, and thank you. I really only see stacking issues do to tip angle and not so much because of reflex. That's why I put the center of bend in the limbs nearer the handle and not center limb, and definitely not centered towards the tips.
Hi...is the belly of the now facing up...
Do always heat the belly and does it help to have the single growth ring
If you're asking if I heat the belly to harden it, usually only with ash and elm, and if the bow isn't backed it needs to have a clean single growth ring.
How well does amarican hornbeam or muscle wood take to heat bending. The best bow i have is hornbeam. But it has some bend set into it. It still shoots like a lightning bolt at 45pounds at 21inchs. But i wonder what would happen if it straightend it
On a scale of 1 to ten, of woods that I enjoy shaping with grease and dry heat and retain the bends, I would rate osage and mulberry as a 10, white ash and almost everything else as an 8.5. and hop hornbeam (Ostrya virginiana) as a 3, and I'm being generous. I don't believe I've ever seen an American hornbeam (Carpinus caroliniana) so I haven't a clue really. I know that both of these hornbeams are in the birch family, so hopefully genus Carpinus is more cooperative than genus Ostrya and act more like paper and yellow birch when heat shaping. In any case, approach with patience and don't go for big bends.
J R's Place good to know thanx
I’ve got my Osage bow roughed out, top limb has a sideways curve and some propeller. Limbs are still pretty thick with little flex yet. Should I get the. Bending before heat bending??
Hi, if it was me, I would work it down enough to straighten the ginks out of it before tillering. I hope that was your question.
@@johnjriggsarchery2457 Thank you for responding! This is my first Osage bow, what thickness of limb do you begin tillering at? I'd like to end up around 65# @ 30" (I'm tall with simian arms)
You do amazing work do you do commission work
dustya1982 Thank you, and I do. My main job is running a nature preserve and interpretive center. We're in the middle of the heavy tourist season so all of my time is called for. I'll be back making bows, though in a little less than a month.
J R's Place that's awesome I'm looking for a for a reproduction of my father's bow it was a lot like this Osage gull wing with recurved tips about 46" in lenth
I read once that the Indians would grease the bow with bear fat, stake the bow on edge and bend and hold the shape with wood stakes and build a fire near it to heat.
Thank you for that. Simple, but it sounds effective.
Osage looks like it bends really easy ! How thick is the limbs? How would you compare bending hickory vs Osage?
I'm putting a lot of pressure on it so it might be hard to really gauge it from watching it. The limbs are about 1/2", and it's relatively narrow. That's a tough question because it doesn't take much of a difference in thickness to make a big difference in bending resistance. I would have to tip it towards osage. If you have two 65 pound bows of the same length and same basic design, the osage bow can be narrower. Osage has a much higher Janka hardness than shagbark hickory by far, a slightly higher crushing strength, but what is odd, has a slightly lower modulus of rupture. All in all, it's a bit stiffer. This is just my opinion, but I believe in raw strength, the hickory probably has a higher tensile strength. Not much, but higher. As far as being able to take shaping like recurves and remain bent, I think osage takes that one, and the bane of bow makers, string follow, osage is superior. Hickory is a really good bow wood, and I've used it quite a bit, but I think osage is the king of bow woods. Yep, yew is awesome too, but I place osage higher than yew mainly because of it's toughness and durability. As much as I like yew, it's so soft, it can be dented with a finger nail. When the bow string breaks, you could beat something to death with an osage bow without it getting damaged. Can't really do that with a yew bow as easily. Thank you for asking.

Going to Experiment totally primitive methods to heat bend a bow, dip it in water for a couple minutes and then over a fire. Of course not over the flames though.
Think it will work?
Very cool ?
Thank you. I appreciate that.

Hi River Rat, Thank you. I just now received notification for your comment. TH-cam better get on the stick.
