Author Topic: 60" 65# Osage takedown Buffalo Bow? (Read 11230 times)

Sidewinder · « **on:** February 21, 2008, 05:00:27 pm »

I want to make an Osage takedown with either buffalo bone or horn for the handle section as the joining portion. Could you guys post some of your takedown designs. I have seen Mark St.Louis's and although I would like to get the performance his limbs produce I think I have a different handle and limb attatcment idea in mind and would like to see what is out there. The goal is 65#@26" for the buffalo bow for next years buffalo harvest. I have a couple of real nice billet sized pieces I have been wanting to do a splice or takedown on and this is what I have decided to do. I have access to a fella with an exceptional lathe set up and think we can get the take down handle joint pretty flush with about any material his lathe will handle, so although its not as paleo as it could be I think it is way do able and should be both unique and practical. As you all know I am a new bowyer and your suggestions are greatly appreciated. Danny

You got me,I am working on a take down now but it is Brass and steel.I am
sure it can be done just don't know what to tell you.Just go for it with your
idea and show us what you come up with.Good luck on this project.

Thanks Pappy, I have had a fella offer me a piece of Titanium tubing for the joint section, but I thought it might be neat to have the bow made from all natural materials. How do you intend to do your attachement of the tenons to the handle section? Are you going to make your tubing oval? Try and give a description if you can. Danny

Here are a few pictures on where I started and where I am now.

There you go. Thats exactly what I needed to see. A Picture is worth a thousand words.I don't see any reason why bone or horn either one would'nt work with ends like that. what are they 1 1/4" across? Do you rough out the limbs and prepare the joint and then tiller it Pappy? Whats the thinnest tenon you think a guy could go with? Considering that I think bone or horn might be a little thicker than metal for same the rigidity, I should have known that you woulld have a functional design. I love your work. Danny

Your idea is good and sounds interesting,but what worries me is the probability of the horn splitting? If it was me I would make the horn "tube" smaller than what you want your finally handle to be and then wrap it in sinew and polish it up after its dry. Maybe covering the sinew in cherry or birch bark also. Thats just me though, and I tend to like to over build things a lot, especially handles...

Very cool and interesting I hope it works out. post pics
Pappy was that from billets or did you cut a finished bow in half? Jesse

Leg bone of a Moose might work for a takedown

Alex, I have not worked with bone or horn yet. Your insight into possible failure of that material is appreciated. I am sure there are those that have tried it, is there not? I would like to hear from anyone that has tried it and what is their input. I am in the conseptualizing stage at this point and just like a lump of clay am very pliable. Not having shot or handled a takedown of any kind up to this point, I am just curious if we can keep the pressure from being too great in the handle area by buffering the bend a couple inches in the limbs before the fades. Kind of like I did on my glue on handle pyramid bow. What do you think of that? Danny

Mark, how about leg bone of a buffalo? Danny

Marc St Louis · « **Reply #10 on:** February 22, 2008, 07:26:10 pm »

Don't see why not Danny. Bone is extremely strong

Sidewinder · « **Reply #11 on:** February 23, 2008, 02:47:30 am »

Then its settled. Its Bison femur bone for a handle splice and horn tip overlays for show. Gut string with a buffalo bugger for a knock point...lol but seriously...alll of the above without the bugger. Danny

I had a similar thought a while back, so I got some big dog bones at the pet store (cow) and did some experimenting. I put some heavy dowels into each end and put some strain on it to simulate the draw weight strain. The bone crackled before it felt like typical draw weight. I got frustrated and shelved the project temporarily.

Please don't let this deter you. My experiment was very crude, and didn't use working limbs. I didn't even measure the weight. Just be aware that the bone is a big suspect for a failure point. I suggest you do some proper experimenting (unlike me), before getting too far into it. You might have to come up with some sort of reinforcement.

There's an interesting thread on Stickbow, about some T/D techniques using angled cuts. Maybe it will be useful for your design:
