Title: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on March 31, 2013, 11:46:00 PM
Last year at the Tenn Classic Clint Anders(osage outlaw)gave me this cool stave from the giant osage he harvested in 2011. I was excited when he gave it to me not only because it was from "the" tree but also it had a cool knot hole in one end...

(http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurve002_zpsc16be34a.jpg)

 A few weeks ago I decided I wanted to build a short osage static recurve with sinew backing. After looking through my stash I decided to take a close look at the stave Clint gave me. After studying this stave I realized that the knot was too close to the tip for my comfort. I think it would have excess physical weight with the extra wood around the knot and it would adversely affect the way the bow shot. So I did the unthinkable. I cut this stave at 56", a few inches below the knot. I then chased a good back ring, marked the center line and them marked of the back prifile.

I cut it out to 1 3/4" wide most of its length then it tapers to 1" at the tips for now.

Next I cut the limb thickness to 3/4" from tips to fades.

(http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurve009_zps189c49c8.jpg)

...and this is where I am now. I will reduce the belly beginning with a farriers rasp until I get to floor tiller stage. Then it will be a scraper and maybe a little work with the Nicholson #49 if needed. At some point I will bend the recurves. I made this form when I first strated thinking about this recurve. It has the same radius as my other recurve form but this bow will have 6" recurves and my older form would only make 3" recurves. Here is the new form...
(http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurve-form_zps84d3f790.jpg)

This bow will be a long drawn out affair especially since it will have a sinew back but I will post pics as I continue on.

Bert, you are my inspiration and I will bend Matt Wirwicki's ear when I see him at the Tenn. Classic. If either of you guys have any suggestions or other ideas please chime in. I have a pretty strong constitution. d;^)
 Unfortunately this one will take while to complete. This time of year my time gets limited but I'll keep you guys posted as I make progress.

Today I thinned the limbs to about 5/8". One limb had a slight crook that I heated and clamped to straighten.
 (http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurve002a_zps294ddd91.jpg)

 (http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurve004a_zps83b2e9f4.jpg)

 (http://i5.photobucket.com/albums/y199/PatBNC/56asinewbackedstaticrecurve006_zps19663bd2.jpg)

After that cooled some it was time to recurve the limb tip. I had to modify the form a little so I could use screw clamps, then I added some oil and began heating. As I heated the belly I could feel the resistance lesson. A few splinters began to lift on the belly so I supported them with a clamp and continued...
 (http://i5.photobucket.com/albums/y199/PatBNC/56csinewbackedstaticrecurve011_zps1eaf9766.jpg)

(http://i5.photobucket.com/albums/y199/PatBNC/56bsinewbackedstaticrecurve010_zps606baab1.jpg)


I'll fill the splinters with super glue and if necessary I'll add an underlay to support the recurves. Now she'll sit in the form until tomorrow to insure the wood has completely cooled then I'll recurve the other limb.

Post by: Roy from Pa on April 06, 2013, 05:23:00 PM
Cool Pat, don't those splinter hurt anything? Nice looking stave there too. Just drives me nuts when I see how much some of you guys reflex the tips:)
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on April 06, 2013, 05:26:00 PM
Roy, the splinters aren't very deep. I'll super glue them and if necessary I'll add an underlay to support the recurve later.
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Roy from Pa on April 06, 2013, 05:33:00 PM
Guess you will file a groove down the belly to hold the string on? What actually do you gain by recurving the tips so much?
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Buemaker on April 06, 2013, 06:13:00 PM
Interesting, do you think the splinters would have lifted If the tip had been boiled or steamed? Bue--.
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on April 06, 2013, 07:50:00 PM
Probably not Bue but I have always done it this way. The limbs are thick and the splinters don't go deep into the wood, they follow the early growth ring but are pretth shallow. On other recurves I'm made a bit of super glue in the splinters and clamped worked well. By the time the final tips are shaped they won't be noticable. I will probably add underlay for protection.
 Roy this bow will be sinew backed and will be pretty short even for my 26" draw. These recurved tips will be static or mostly so. This will put a lot of strain on the smaller working area of the limb and that is where the sinew comes into play. The sinew will also be highly stressed adding speed to the bow(all in theory)but hopefully also lots of protection for the back. The recurves also allow this short bow to be drawn without stacking(string/tip angle)and less finger pinch. Heck, it may blow all to hell on the first draw but it is something I've wanted to make for a while. I've made 60"t/t recurve selfbows from osage and elm but not one this short and not one with sinew backing.

Post by: LittleBen on April 06, 2013, 08:53:00 PM
I made a 58" ntn hickory selfbow with slightly recurved tips. This is gonna be something well beyond that though. I'm very interested to see how this comes along. I prefer shooting a longer bow but I love looking at these shorter bows with the sinew, the reflex, the recurves etc. Keep it coming!

I'll need it Roy!
 LittleBen, I also prefer longer bows. I recently built myself a 64" osage selfbow with flipped tips.  These shorties are fun to shoot but hard to get used too. It took me the longest time before I was consistant enough to feel comfortable shooting them. Once you work that out they can be real sweet shooters.

Pat try putting a band on the belly like a piece of metal ruler.  Go into the Archives and find J. D. Jones build along static recurve.  Lots of information on making Recurves in that build along. Here it is.

Great thread Pat!  I'm gonna try a curve soon.  I'll be watching and trying to learn something.
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on April 07, 2013, 11:14:00 PM
rainman, if you look at the first pic of my form you will see the metal band on it. I didn't have enough hands to get it to work out so I removed the band and altered the form so I could use the screw clamps.

I took the first curve off of the form. This first pic is sighting down the bow. You can see that the first curve is kicked to the left. I will adjust that later with a little heat and pressure...
(http://i5.photobucket.com/albums/y199/PatBNC/-osagestaticrecurve2ndcurve001_zpsec715d80.jpg)

Here is the first curve...
(http://i5.photobucket.com/albums/y199/PatBNC/-osagestaticrecurve2ndcurve002_zps4cdb0d15.jpg)

and the second curve heated and clamped...

Post by: Bowjunkie on April 08, 2013, 05:51:00 AM
That's a serious curve. I like it. It'll have a nice side profile.

I made one like it, though not quite that short,, backed it with sinew, then sturgeon, then killed a buck with it  :)

Post by: Pat B on April 14, 2013, 04:37:00 PM
I did a little more work on her today. I decided to chase the next ring down because it is about twice as thick as the top one was. I needed to reduce a lot of weight anyhow too.
It was time to align one of the tips that was way off. I clamped her to the jig to be sure she was held soundly  then I began to slowly heat the entire limb belly. After it was good and hot I added the next clamp to one edge to reverce the twist. In then heated the tip just below the curve and when it was hot I used the para cord to torque the tip to the left. I then reheated the limb and added the wood clamp to bring the limb over to the left a bit and retightened the para cord holding the tip...

...and the other tip looked OK to me and didn't need any alingment yet. Both will probably need a final alignment later...

I got the tip underlays bent yesterday. I was gonna use ERC but couldn't get them to bend with steam so I cut a few yew pieces, sanded them to about 3/16" thick and they bent well. It was suggested that I wrap the pieces in a wet towel and microwave it for 2 minutes...BINGO, they bent well and held much of the bend. I also bent 2 narrower pieces of a dark tropical wood to go over (under) the yew.
I'm gonna try to get the belly side of the recurves flattened and do the glue up today. I'll post pics as I go.

Pat,
See what you started, now there is three of us working on sinew backed bows, as soon as my Carpal tunnel surgery heals up I will be pounding some leg sinew to back a Hickory Recurve I have been working on for a while, am looking forward to seeing your process and rollingrock's as well.
Regards.
Bert.  :bigsmyl:

Post by: fujimo on May 15, 2013, 09:48:00 PM
that sounds interesting bert, how does the hickory work with the sinew, being a better tension wood than a compression wood.
i have a nice hickory stave that i have had on my rack for at least 5 years, and am always tempted to cut it into backings, but your idea sounds"cooler"   :D  
really want to see how these all turn out.
just as a matter of interest, what would be a good length of recurve for my 29.5 " draw@ 50#- probably would like to build it to bend thru the handle- so that i can get it a bit shorter.

Wayne I don't want to highjack Pat's thread but if you are going to sinew back any kind of bow and gain performance I wouldn't go any longer than 60".
Here is a couple of pictures of where I am at but I will have to heal up before I can make anymore progress.

I finally had time today to get the string nocks cut in and a little tillering done. After "floor tillering" I realized one limb was a bit stronger so I worked on it first to get both somewhat even then I began tillering. Here she sits before removing any wood today...

 ...after a bit more wood removal and exercising here is where she is now...

 I'm still on the long string. I'm guessing she is at about 70# to where I pulled so I need to get more meat off so I can get her to low brace to see how the limbs line up and so I can get a more accurate weight measurement. Here she is relaxed after her workout today...

Looks real good from here Pat.  I've been following this one real close.  The lilac bow I was working on came in under weight, thought I would try to sinew it to salvage it.  How big of an increase in draw weight can be achieved with sinew?
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on May 19, 2013, 04:14:00 PM
Dan, depending on how much sinew you use I'd say up to 10#. The sinew will make it a zippier bow so it should shoot like a heavier bow. How long is your lilac bow? You really need to stretch the sinew to get the goodie out of it. If the bow is too long the sinew won't stretch enough.
 You could flip the tips and temper the belly and maybe get a few more pounds too.

Post by: Dan Landis on May 19, 2013, 08:19:00 PM
Pat, It was around 64" but cut it to 60", but didn't think it felt like I gained much, so I put it away till I get some more sinew.  I would be happy if I could get 10# out of it.  Right now it's in the low 40# range.

Post by: LittleBen on May 19, 2013, 09:57:00 PM
That a bow right there Pat! Not much limb on it though, if that makes a reliable bow it will eb a testament to your experience ... not that I have any doubt you'll get there. I really like the recurve loook. It's going to be sweet.
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on May 19, 2013, 11:17:00 PM
There isn't much bending limb, Ben. I will bring the bend back into the handle so I will feel it give at full draw. 3 courses of sinew should help it hold up if I do my part.
 Dan 60" will stretch sinew. Kick the tips up a bit too. Both might just get you 10#.

Post by: Dan Landis on May 20, 2013, 10:07:00 PM
Thanks Pat, How much sinew do I need to make it work.  So far I only have one deer worth, front & back leg tendons and the back strips.  Hope to gather the rest this fall from a local butcher shop.
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on May 20, 2013, 11:12:00 PM
I'll use mostly back sinew. I like the longer length and ease of seperation. It may take 10 or more, I won't know til it is done.

Pat, would you post a few pic's of the sinew processing before you glue it on the bow please, that is kind of where I am at, altough all I have is leg sinew.
It's looking great sofar, thanks for sharing.
Bert.

Post by: Pat B on May 21, 2013, 10:36:00 PM
I will Bert but I'm not sure when that will be. I want to get the bow to brace first and make any corrections before adding the sinew.
 The last sinewed bow I built was with back and I love working with the longer strands. It makes a neater application for me. On the other sinewed bows I built I used either deer or elk leg sinew. They were seperated by length so I started with the longer stuff. When it was dry I added the mid length stuff to fill in bare areas and then use the shorter stuff to even everything out.

Looks sweet, Pat!

Question. How do you string a bow with recurved tips? Do you use a stringer?

I attempted static recurves on a bbo this spring and couldn't string It by hand like the other longbows I've made. I usually place the lower tip on my instep, pull the handle and push the top tip as I slide the loop into place.
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on May 23, 2013, 11:51:00 AM
I will use a stringer until I get it complete and if it is difficult to string after that I will continue to use a stringer. I usually use the push/pull method like you. These statics can be difficult to string because they can twist in your hand if you aren't push/pulling evenly. A stringer is the safest option.

Post by: fujimo on May 23, 2013, 01:58:00 PM
i have taken to cutting an extra string groove above the nock, on both ends, and then use a sufficiently strong cord with a small loop in each end as my stringer, quick, easy and compact.
if i am using a bowyers hitch on the bottom of the bow string, then i use a leather boot on the bottom  nock and a loop on the top.

but i find myself favouring the former , more and more nowdays.

i am also working on a self bow with flipped tips right now, sure is fun, really like the look and feel of them/it.
gonna be more in the pipeline in the future.

thanks for the inspiration from this thread.

I did a bit more work on her today. I braced her low to see how the string tracks and how the tips line up. Here she is at low brace..
  (http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurvetillercontinues001_zps293a7481.jpg) (http://s5.photobucket.com/user/PatBNC/media/56sinewbackedstaticrecurvetillercontinues001_zps293a7481.jpg.html)

...the string tracks pretty good...

and the tips look pretty good too...

I've narrowed the tips some and got the basic shape of the handle. I wanted the handle close before adding the sinew. That will be my next step, adding the first of 3 courses of back strap sinew. I've pulled her to 20" and she pulls 60#@20"/going for 26") To be continued!

Post by: Pat B on June 16, 2013, 03:29:00 PM
Eric, that is part of my ADD training. If I clean up I can't find anything. d;^)

 I started the sinewing today. First I scored the back of the bow where the sinew will go to help with the adhesion of the sinew and hide glue. I used a toothing plane blade for this...


Photobucket is screwing up so I'll post pics later.  Sorry!
Title: Re: 56" sinew backed osage static recurve...the beginning.
Post by: Pat B on June 18, 2013, 10:40:00 PM
For some reason I can't retrieve my pics from Photobucket. Can I cut and paste directly from my computer to TG now?

...anyway, the sinew I layed down on Sunday dried nice and clear so I added another layer today. After it dries for a few days I will inspect the sinew well and determine if I need to add more.
The next step it to wait a month or two for the sinew to cure then I will resume tillering. She was about 80#@26"(estimated)before adding the sinew so I have a lot of meat to take off. I want the final bow to draw about 55#@26".
As soon as I can get Photobucket straightened out or find another avenue I'll post pics.

Post by: Pat B on June 19, 2013, 03:42:00 PM
I think I finally got this photobucket crap figured out. We'll see.
I used a toothing plane to score the back of the bow to help the sinew adhere. This is the toothing plane blade...
 (http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurvesinewingbegins003_zps8a60ecff.jpg) (http://s5.photobucket.com/user/PatBNC/media/56sinewbackedstaticrecurvesinewingbegins003_zps8a60ecff.jpg.html)

...and the results...
 (http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurvesinewingbegins004_zpscba7db81.jpg) (http://s5.photobucket.com/user/PatBNC/media/56sinewbackedstaticrecurvesinewingbegins004_zpscba7db81.jpg.html)

I then sized the bows back with hide glue and when it dried some I began adding the first of the sinew. I like to start at the handle and work out both limbs centering the first of the sinew on the limb...
 (http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurvesinewingbegins006_zpsae65ae5b.jpg) (http://s5.photobucket.com/user/PatBNC/media/56sinewbackedstaticrecurvesinewingbegins006_zpsae65ae5b.jpg.html)

Also, I strung the bo backwards(into reflex). With the tips on the floor the handle is 4 1/2" above the table. Once back strung the handle sits about 7 1/4" above the table.
 (http://i5.photobucket.com/albums/y199/PatBNC/56sinewbackedstaticrecurvesinewingbegins008_zps432e3fad.jpg) (http://s5.photobucket.com/user/PatBNC/media/56sinewbackedstaticrecurvesinewingbegins008_zps432e3fad.jpg.html)

I then started dipping the sinew in the hide glue, squeegieing off the excess glue and layed it down...

and the back completed with the first layer...

Ron, you ought to be in my shoes with the waiting thing. It drives me nuts just knowing I have to wait to get the best results. I'm keep this bow in the utility room so I don't see it unless I go in there...out of sight, out of mind. I'm as curious as the rest of you guys to see how this bow will work, if it will hold together. This is a first for me, not only the big recurves but also the short overall length of the bow. This bow will have less than 18" of working limb on each side.
 She has already increased in reflex by 1" or so. The string I used to back brace her is not slack yet but has loosened up quite a bit already.

This coming weekend will be 2 months since I put this bow up to rest and cure. My plans were to begin the tillering at 2 months. We have had such a wet summer that I have decided to wait until drier weather before I stress her. It could be the difference in a zippy little bow or a cool looking slug and I would prefer the former.   ;)    Once the weather breaks and the humidity drops I'll be ready to get her done.
We had 10" of rain in June, 22" in July(only 2 days with no rain) and already 6" for August putting us well over 75" for the year so far. Our normal yearly rainfall is about 73". ...and we don't have A/C!   :o

Well guys I've taken her out of the utility room and have her in full sight now. We have had a pretty dry Sept so far. We can already feel fall in the air and that air is dryer. Now all I need is the time to work on her.
Scars, she is 1 5/8" at the fades and out about 12" before tapering towards the tips. I use two thick layers of cow sinew on this bow. It is the first time I have used cow sinew so I don't know how it measures up to deer or elk sinew. The bundles I laid down were pretty thick but the way it was shreaded is worked well and layed pretty smoothly.
I removed the back bracing string and the back of the handle is 6" behind the tips. It's gonna be a bitch just getting this thing to low brace height. d;^)

Thanks Pat,
ATARN has a cattle sinew topic they keep right at the top of their "bows arrows and stuff forum" I don't think there will be much difference in performance. Unless you are making a flight bow.
I think you may be correct in sayin' it's going to be a bear to get it to low brace. Might need a bracing board. Where did you get cattle sinew?
My horn bow is 1 7/16" wide and 3/8" thick at the fades I think I will thin it down some more.
Your bow is what gave me the incentive to start my horn bow. Thanks
Joe

Joe, I was gonna build an Asiatic horn bow but it seemed too daunting of a task. I have watched James Parker building his horn bows and at different stages of the process. I will probably build a Plains style horned belly bow or at least my version of one. That is for next year.
I got the cow sinew, already shreaded no less in trade for a bundle of hill cane. I liked working with it.

Post by: scars on September 20, 2013, 03:25:00 PM
With the craftsmanship I have seen in your bows I would have no doubt you would excel. I too plan on building a few Native horn bows. I also want to make a Pacific coast painted bow. And a rib bone bow. A sheephorn/elk bow with no wood core is tempting also.

a good place to get cattle sinew, is find a feedlot in the area, and ask them if you can go over to their dead pile, and cut the tendons off, they usually die from pneumonia, colic, "the spins" or a lead pill,not anything that is contagious to human contact.
chat to the cowboys at the feedlot- make friends with them, trade them some gear- they are worse gear freaks than trad archers, offer them a new hat or sumpin' for"x" amount of sinew.

I got back to work on this bow today after quite a long time. I added the sinew on 6/16-18/2013. After a few pulls on the long string and scraping a bit where needed I got her to low brace to see how everything lined up. No real problems. One limb(lower) was a bit too stiff and had a few stiff spots so I used a scraper to correct those problems then raised the brace height to where it it now, about 6 1/2" from the back.
 Anyway here are a few pics I took today..
Braced...

drawn to 26"...

and just after unbracng. I shot four arrows through her then let her rest at brace for about 1 hour before unbracing and taking this pic...

There is still a lot of work to do. She is stil a bit heavy(60#@26") so I want t reduce that some. I still need o shape and finish the tips and handle and put lots of arrows through her before adding the finishing touches(tip overlays,carp skins a floppy est and handlw wrap).

The Mongols used domesticate cattle sinew so I don't see how it could be subpar.  I have heard that it is also but I just don't believe it.

Post by: Pat B on October 08, 2013, 10:31:00 PM
Dan, my friend James Parker requested domestic cow sinew for the Asiatic Horn Bows he builds. I really think sinew is sinew, some is longer than others, some seperated better than others, some are greasier than others but sinew is sinew. d;^)
I really like how this cow sinew is to work with. I got it already shreaded and clean so I don't know what it takes to get to that point but as far as working with it it is up there with any other I've used.

I did a little scraping on Saturday afternoon and got her weight down to 56#@26"(pulled to 27) set the brace to my fistmele and went out and put another 20 arrows through her...and she is quick! I was shooting parallel poplar arrows at about 10gpp. They shoot straight and true and did I mention fast. d;^)

Well, she's finally done. She is 56 1/2"t/t, she has yew and ipe recurve underlays and leather saturated with super glue tip overlays. The handle wrap is hemp cordage set in Massey finish and she has a Floppy Rest. She has 3 layers of cow sinew put down with hide glue and that is covered with Texas Diamondback Watersnake skin put done with hide glue also. Five coats of Tru-Oil for the finish and I will do a quick spray of satin to cut the shine.
I'm not sure of the draw weight but she is heavy; probably over 60# maybe even 65#. I'll have to reduce that if I plan on shooting her much.
Here are  few pics. I'll get a full draw pic up later today.

I knew my old spring scale was off but I didn't know how "off" it was until Stringstretcher sent me a new digital bow scale. I put Lil Thumper on my bow scale and it showed 56#@26" but on the digital scale it was more like 65#@26". I have since reduced her to a true 56#@26" and I'm still pleased at how she shoots. At least now I can shoot her more than 2 or 3 times and get a good clean full draw. d;^)
