Title: sinew backed osage recurve 46" nock to nock,,187fps
Post by: bradsmith2010 on March 28, 2021, 08:50:31 pm
  I posted this before in progress and still contemplating, I can only draw it to 21 at this weight, was thinking of taking it down to say 50 at 23,,
  right now it was 48@20 I drew it to 21 in photo and think its about 50#,,
  I did something different on this it was bending too much at top tip below the curve, I added sinew and heat treated that one spot,,wasnt sure how that was gonna go but seems ok,,
  the braced profile looks bit funky,, unbraced looks ok, so I just contemplating now, may shoot it a bit as is and think about it, pics to come
  maybe a couple scrapes on upper outer limb,,???

more pics and test shot,, ;D of course im gonna paint it crazy and put a handle,,thanks for your patience,, and probably shoot it through  chrono when I get it out to 23, the belly crack is from sinew drying , ,I didnt seal the belly well enough,, it goes back to rest at about 6 or 7 refelx, it is not fun to string at all :NN

That's pretty great there Brad.....can't wight to see it all painted up! :OK

I guess you steamed or boiled in the curves before sinewing?

Post by: bradsmith2010 on March 29, 2021, 12:57:48 am
yes I boiled them,,they were too big and I couldnt get them to line up,, so I cut them shorter,, they were more stable and I was able to get them to work,,I remembered why I dont make recurves,, (-S

thanks guys,, yes its pretty "snappy" I will try to test it soon,,Im gonna narrow the tips a bit and have to align one some too,,not bad but the string is off to one side more than I like on one tip,,

Nice looking little bow Brad. Looks like it will throw and arrow pretty quickly. Can’t wait to hear.
Title: Re: sinew backed osage recurve 46" nock to nock,,about 50#@21
Post by: bradsmith2010 on March 30, 2021, 04:42:42 pm
ok heres what happened and didnt happen, I pulled it to 23,, and I heard a tick noise, so I passed out ,, well not really but kinda,,
so I looked and one strand of sinew had pulled up, so I drew it to 23 a few more times to see if it was gonna blow, and it shot fine, right now I am heating some hide glue and gonna wrap that spot, Im not proud,, when dry I will continue with shooting through chrono at 23 ,, which Im thinking is gonna be 55 plus,, pounds, it should spit an arrow pretty good at that draw,, I got some fast flight, is that  natural material,, :D and will try with that just for fun,, of course I will put a sinew string on it for the deer and turkey to admire,, :D

Beautiful bow! With those recurves and that overall reflex must be snappy.

What happens if a piece of sinew gets lifted? Is it as bad as a splinter lifting on a self bow?
Title: Re: sinew backed osage recurve 46" nock to nock,,about 50#@21
Post by: bradsmith2010 on March 31, 2021, 04:46:01 pm
no I dont think its as bad as splinter,, just one strand didnt effect anything,, I just wrapped it to be sure it dont do it again,,

Great bow. Ticks of any kind are the worst.  Hope it keeps shooting well for you.

Post by: bownarra on April 01, 2021, 03:52:37 am
If you applied some very hot, thin glue to the spot it would 're-activate' the glue and you'd be good. No need to wrap it. Do you see a spot mid upper that looks like its bending a wee bit much?

  488 grain arrow 184fps,,roughly pulling,,55#@ 23 inches,,I didnt have anyone to spot for me, but pulled as best I could to mark at 23 inches, its close,, thats 8.87 GPP 
   this will give you rough idea what a short draw will do,,you can do the math, if I  pulled it to 25,,with added draw weight and power stroke,, it would really spit one, but im afraid it would blow, so not gonna try it today,,

Ok, I have got to build one! 
I don't have any osage, but Heat Tempered HHB like what Marc St. Louis uses should work fine, especially if I go up to 62" to handle a 26" draw.

You are really starting to get me more interested in shorter bows.

i think its good to know how to make them,, then your shorter staves become more valuable,, :D
thanks Fox, I was pleased,,it gets good arrow flight too,, :)

That's good it shoots straight too!

I really love smaller bows. I have a hard time not always smacking things with longer bows ;D

Ok, that makes sense.  I really like the long smooth draw, but I've got to admit my 74" bow is a little awkward. :)

  ok here is the finished back, I have a design in mind for the belly,, I will try to shoot it at 24 inches,, I was gonna pull it on a tree in case it blows,, but you have to have some confidence in your work ,, so I gonna just pull it,, ;D
  this is more info than you need but if you got this far with me, I will tell you a little about the art,, I have been inspired by many cultures, this is a combo of alot of different designs some imagination and some from traditional images,, all mixed to gether,, I am not a purist about the art, so am not tied or constrained to any one set of images,,of traditional art,,
I just improvise and paint what comes to me,, I think the bow dictates what is to come,,I just follow,,on this bow I used ink, gouache,,acrylic,,,the underpainting was acrylic,,I like it and it protects the sinew,,I may but a leather handle it will cover some of the art, but I will know its there,, I have a design in mind for the belly,, but my brain hurts from the detail of this one, and will take a few more days to do that, enjoy, and pm me if I can help with any project you have with art for your bow,,,,,

Title: Re: sinew backed osage recurve 46" nock to nock,,187fps
Post by: bradsmith2010 on April 08, 2021, 03:15:24 pm
ok I tried to pull it to 24, but it made a creaking sound a little past 23 so I lost my nerve,
so I think i nearly got it to 24 when it shot 187 fps with the 488 grain arrow,,Im am afraid to weigh it,,let me get my nerve up, but I think its a bit over 55 at nearly 24,, ok I know thats vague,,but thats it for today,,  (lol)
  believe me I really wanted to pull it a little more and hit 190 so I could brag about it,, but then I could see the bow in several pieces at my feet in my imagination, and thought better of it and just made myself stop,,,, )P(
  ok its about 51# @ 21,, I was brave enough to pull it that far,, so that would put it about 56#@23  so when I pulled it past 23
   so about 58 little past 23,,roughly 8.41 gpp,, roughly,, 187fps with 488 grain arrow,,
   I know I promised to hit 24 inches but when the bow creaked I lost my nerve,, ;D

Post by: bradsmith2010 on April 08, 2021, 05:20:39 pm
you are probably right, since it did not blow up,, I am erring on the side of caution, since I was attemting to draw it more than half the bows length, that is usually my stopping point,,
but great observation, the paint can make a noise sometime that is scary,, (W
