I had a short 5 year old prestine osage stave had it inside for 3 years I decided to make a Laubin inspired short osage/sinew bow 55 ntn going to try to get it to as close to 30 1/2" draw at 45lb as posible this is about the shortest bow I have tried to get to that draw but this is the stave to try it with I relies its pushing it but a interesting challenging build !
-
Are you going to recurve the tips?
-
Yep for sure probably a nice retro bend Im going to tiller to about 20" first before bending the hooks this one is going to be real close to Laubin style with out the pin knocks so I can use a primitive stringer ,Im not exspecting stack free on this one ;D
-
Those style of bows are made to shoot exactly half their total length. Don't try for 30.
-
Well will see Im going with what looks safe if 27" -28" thats fine too ,this bow really has no practical purpose for me just making it for a challenging & fun build !
-
You know Patm the more I think about it Laubin made some 52" bows that pulled 65lb @26" he believed quality osage was as good as horn in compression, Im not saying I beleve it but this stave is one of the best I have ever seen no knots beutiful rings so Im going to take this one to at least 29" @45lb or if need be drop the weight some, I think it will take it ,Im using elk sinew and letting it cure at least 4 months or better , I will post more when tillered to 20" & brace just got it to long string !
-
Those were D bows though. The Martin style is a different animal.
-
No he did it with the Robert Martin style also but they ended up with string follow in the working limbs but he didn't pre reflex the limbs before sinew like I did so mine might be stressed more , well the best thing to do is get this one built and see where it goes really the only way to find out ! Mine is a little over 55" ntn so 28" is realistic beyound that I don't know !
-
26 is half of 52.
-
That's what I'm saying 55 1/4 " 27.625 so for sure 28" and go from there !
-
That's the sensible limit. Going beyond that will just degrade it.
-
My advice: Get it really perfect at 27". I mean like really perfect, no set tiller. Then send it to me! (Oh, and maybe try for 50# if it's not too much trouble.)
-
:D
-
Looks and sounds like a great piece of hedge. Will follow along, and good luck. I'm sure you'll know when enough is enough as far as draw length goes.
-
Interesting, I presume you will be making it a bendy handle? Rigid handle is almost making it fail by design. 30" is a handful of inches too many haha!
Horn and osage similar in compression....? I don't think so!
Good luck with the bow :)
-
Well will see how far it will go play it by ear there are some guys on other sights that are streching short handled osage/sinew bows some crazy draw lengths to the point of string almost coming off but like was said with set it might take it but performance wise nobody publishes , Laubin actualy said that osage horn comment the funny thing is he made composite horn bows also ,but no way all though I suspect quality osage will strech farther then average osage ,well like said get this one to 28" & go from there , one of the problems I have found with these natural bows is the quality of the wood for comparison is not always the same & osage really varies in quality , stave to stave I have atleast 40 osage staves hanging in the shop but none as good as this one but you really never know tell the rubbers on the road ! Im not saying its doable with this stave Im just saying this one might strech a bit more then average !

There have been a bunch of these short bow long draw bows made around here from some very talented bowyers over the years here is one example but many in the archives http://www.primitivearcher.com/smf/index.php/topic,52218.0.html

American Indian Archery.

Also different articles by him on the web to !
-
Really no mystery to the Miller design it pretty much a short static leaver bow he did usualy pin knock his bow and didnt reverse string for sinew but he made a lot of the design !
-
I think with sinew....and perfect tiller..you can push the draw..maybe won't last as long as a more conservative design...but then it might,..pope over drew museum bows that were pretty old...it will be fun to see what it does...that's why I do it,,,,,have fun...
Just test it all the way out,,,,you'll know the sweet spot for next time
-
I think u can do it )P(
-
Lots of discussion about how far it can be drawn, but doesn't that depend on the sinew to wood proportions? more sinew=more draw length possible?
-
Yes, Willie it is important to get a good layer or layers of even sinew down...Stick knows how to lay sinew for sure and that will be the key...Even a perfect stave like he has here will benefit...Sinew weight doesn't really come into play here with this design as a deterrent...It will mostly be applied to the working area just above the handle...The light levers will slam home quickly...The project he posted the link to between Rich and myself created the fasted bow I have ever shot...I still have that bow and it still shoots awesome arrow speeds...I'm not about speed but it is still a producer after hundreds of shots...

I was thinking about giving this a try only last weekend - so I will certainly follow this. Glad you are giving it a go!
-
There seems to be some confusion about the tip shape of these bows. They are not straight levers but rather very sharp static recurves.
-
I mentioned in the OP sinew all though I think it was Simson posted a 57" non sinew osage bow a while back with a long draw , my bow is not going to be a Laubin replicate but inspired by his design, I am adding hooks but not as aggressive as his & reverse stringing , I don't over think the design just build it and apply common sense as I go !
-
when are we gonna shoot it,, (-P
-
Hoping to get the sinew on this month probably let it cure tell December ,I don't want to have to retiller !
