Well since the one I was making didn't want to be a bow. It is an Osage board bow. I made the board myself from a stave I cut in half. It had thin rings thinner then I wanted to try. (http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141220_103501_zpslitqwrmu.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141220_103501_zpslitqwrmu.jpg.html)
The bow is on the right, broken silk back Osage and the sister board.
-
Oh and I had to add some heat to get the tips to line up. Once fished it will be 59" ttt. It was 64 but a big splinter came off the end when thinning it.
-
hope this one works for you Kelly. :thumbsup:
-
Well bob so far so good.
very low brace.

But here is were the string was tracking at that brace.

Working in some temp knocks.

For those. I measured .5" from the tip and 3/16th of an inch from each side and cut with a hand saw. I then took a rattail file and made the corner round. I will get pics of that later.
-
That brace is a bit higher.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141221_111104_zpsmeydwd6o.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141221_111104_zpsmeydwd6o.jpg.html)
I do have it to a full brace now.
But here it is pulling about 30#@20".
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141221_205906_zpsj7evxo1i.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141221_205906_zpsj7evxo1i.jpg.html)
I have it pulling 25" on the tree now and about 40lbs. I need to get it to 27 or so. Just to give my nephew room for error.
-
I am gluing on a bit of spalted hackberry to thicken the handle a bit. I will work a bit more tomorrow and I think I should have it tillered out.
It does have bit of hand shock but I think I will put it on the tree again and see if that right limb looks flat on the outer 3rd like the pic seems to show.
-
got my fingers crossed for the outcome Kelly. that tiller doesn't look too bad maybe a little stiff in the outer third as you said. Hasten slowly! :thumbsup:
-
Best of luck Kelly. Doesn't look bad at all.
-
Thanks fellas.
I edit on pic I had doubles up but the string tracking at a low brace has be added. Short bows are not easy to see what is going on. At least not for me.
-
Ok clapped on the handle to make it a bit thicker.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141222_052241_zpsfjfiz0pu.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141222_052241_zpsfjfiz0pu.jpg.html)
So I just glued on a 4" piece on to the handle it is now about 1.5" thick. it was only about .75" and I really did not like how it felt.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141222_134831_zpsfhyz7nct.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141222_134831_zpsfhyz7nct.jpg.html)
Ok and the tips not finished just showing the rounding of them to keep the edge from cutting into the string.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141222_134853_zpsaceirkzx.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141222_134853_zpsaceirkzx.jpg.html)
and now it is pulling 23" with the extra handle thickness.
(http://i43.photobucket.com/albums/e383/gillk/20141222_135918_zpsltama0m2.jpg) (http://s43.photobucket.com/user/gillk/media/20141222_135918_zpsltama0m2.jpg.html)
let me know what you see in the tiller I will get on it in about an hour.
-
Ok the left limb looks flat and appears to have a hinge trying to develop in it next to the handle. there is a bit of deflex there I will heat out later I think but I will work on the outer third of that one for sure.
-
Kelly, leave the area just off the left fade alone and get the rest of the limb bending a little more. Take 5 full length scrapes and check it again. Do this until that limb bends like the other one.
The outer 12" on the left limb looks a bit stiff also.
-
Will do pat.
-
Ok taking it slow pulled it to 23 shot it at 23 after about 15 total scraps on the left limb. put the scale on it after about 10 pulls on the tree and half a dozen shots. she was at 35lbs. Ok I have had it to so I pull it to 24 no issue start working it at 24 and tic and I feel the tic through the string. let it down and look no missing this one.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141222_162905_zpsiqobyynd.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141222_162905_zpsiqobyynd.jpg.html)
Well I have that ones sister so I will try and keep it closer to 64"
I will post here when I start it.
-
maybe I will replace the name to the thread of the broken bows.
-
ok I have the new bow laid out. I will get it cut and trimmed down to the lines and thinned this one is only a .5". So I use ipe and hackberry lams for the handle and a an ipe power lamb on the back to make the handle stiffer so it does not pop off.
if my handle and fades are 7" should I make the power lamb longer, or just 7"?
-
No pics yet of what I have done. I got the third try going it is a .5" board 1" wide until 8" from the times from that mark they taper to .5". I have the handle area being glued up. Once I get it all glued up I will start tillering the bow. It will be 64" ttt. Trying for 35-45lbs at around 27". We shall see. if this one fails I will be chasing a ring I guess.
-
I'll be rooting for ya Kelly. Don't get in too much of a rush though...
And Merry Christmas.
Paul
-
Hang in there Kelly perseverance does pay in the long run! Merry Christmas and a happy and prosperous new year too.
-
thanks gents. The first was not a surprise the second was. I hope yall had a merry Christmass.
-
hey Kelly- man you are one persistent sonofa.. :D you just dont know when to quit ;) ;)
anyway, you are getting all the right kind of advice by the best out there- so i will not venture into their realm, the only thing i will say- that i have learnt the very hard way-
tis those darn tillering sticks- pulling them out to a long/full draw, then stepping back and taking the photo- to me that usually spells the death of the bow, or at the very least a lot more set. just sitting under full load, while we fart around getting the pic is not good for these wooden bows- i like the tillering tree, with the rope and pulley, i use a nice long rope so that i can get nice and far back for good perspective, and with the mechanical advantage- i can pull the rope with one hand, and very quickly click the photo with the other, then let down immediately, i dont like to hold my bows at full draw more than two seconds- i use 2 sec. because the way i shoot: i pull to full draw, then pause for a second or so, then release.
just what i have found- but everybody does everything a little different
cheers mate

fujimo,
Thanks I use a tree if you look in the pics you can see the hook and rope. I do however hold it longer then I like for It is on my horse and not on a wall so I have to sit on it. If I don't it will just pull the horse. So I tie off the end for a bit to take pics but I don't take pics every time I shave it. maybe every 2 or 3 inches.
In the summer I put it in my vice but it is outside and it has been a bit cold. I need to get pics up of my new attempt. I have cut to its profile and thinned. I am working on a laminate handle. Before I put it on the bow plan on tillering it a bit to see where the string tracks.
I will try and get pics up tomorrow.
-
The board I am using is the sister to the one that I just cracked. it is in the first pic on the thread the one on the left.
-
ok here is the profile pic
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141228_133300_zpsvavnbbuq.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141228_133300_zpsvavnbbuq.jpg.html)
and a brace pic
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141228_144900_zpstyvcy7kz.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141228_144900_zpstyvcy7kz.jpg.html)
it looks like it is bending in the handle a bit much. I have it pulling to 24" and around 30#. I will put some heat on it tomorrow and get the string tracking a bit better then glue on a laminated handle.
Once that is done I will see how it is looks that might make the limbs bend a bit better and increase the weight a bit because there will be a total of 7" less of bending section.
I will get some pic of the heating up after I get it done.
-
A powerlam should extend into the fades. That the purpose of them to stiffen the fades. I would go 2 inches past each end minimum.
-
So mike make an 11" piece to glue on the back of the bow?
-
Ok I prefitted the clamps.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141229_195156_zpsxo27bff1.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141229_195156_zpsxo27bff1.jpg.html)
Then I greased up the area to be heated.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141229_195506_zpspprjicms.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141229_195506_zpspprjicms.jpg.html)
then I heated it up then clamped it and heated it some more then strapped it in place then heated it more.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20141229_201004_zpsmikx0qfx.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20141229_201004_zpsmikx0qfx.jpg.html)
Once cool I will take it off the form.
-
How thick should a power lamb be? I have some white oak, hickory, hedge, ipe, black locus all about a 1/4" thick. Ipe and hedge are a bit thinner but not much.
-
Ok I had a hickory backing strip laying around. It had a not in one end. So I cut out my 11" power lame and had plenty to back that first bow that cracked and lifted one heck of a splinter. Why? well why not?. So I got a bit done on 2 bows.
The strip
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20150102_142838_zpsoj3uwldz.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20150102_142838_zpsoj3uwldz.jpg.html)
The knot
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20150102_142847_zpsrjewnukj.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20150102_142847_zpsrjewnukj.jpg.html)
The Power lam and backing strip cut out.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20150102_143102_zpsehkruhip.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20150102_143102_zpsehkruhip.jpg.html)

The bow with the strip
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20150102_143233_zps0pxa9pxn.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20150102_143233_zps0pxa9pxn.jpg.html)
I thinned both with a hand held belt sander.
On the backing I only did the last 19" of eadh end.
So I mocked up the strip to the bow and then applied the glue.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20150102_153346_zpsnmhlmxg5.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20150102_153346_zpsnmhlmxg5.jpg.html)
And I the handle is getting glued on the second bow. Then I will do the power lam.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20150102_161350_zpsaywkc3ph.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20150102_161350_zpsaywkc3ph.jpg.html)
-
oh and don't tell the wife I glued up the bow on the counter top.
-
oh the crack. I used super glue and lifted the splinter a bit and just filled it with super glue. Then clamped it back down.
(http://i43.photobucket.com/albums/e383/gillk/Shanes%20Bow/20150102_161350_zpsaywkc3ph.jpg) (http://s43.photobucket.com/user/gillk/media/Shanes%20Bow/20150102_161350_zpsaywkc3ph.jpg.html)
-
on the bottom side of the handle- is that an optical illusion, or is there a gap there?
-
might be a bit of a gap. I will look at it later if it is I will fill it with wood glue and saw dust. I know it is cheating but I never seem to get no gapes with my set up so we shall see.
-
if it weren't for bad luck I'd have no luck at all, blues, despair and agony on me. woah
I broke the third one I was working on this is not cool at all. It might be the dryness in the air due to the super cold temps out.
Well I am going to hit the stave pile. I need to get some pics up of some any way for a trade I need to do.
-
geez Kelly seems like you have the same type of luck that haunts me most times.Hang in there son perseverance and all that! :thumbsup:
-
Kelly I think you need to find some better wood. Even if you have to cut two staves in half and splice two good half's together.
-
roy I had made bows for sisters stave of that wood. A very nice one in fact. They just did not like being boards I guess. This one gave in a place I did not expect I will try and get a pic up. Yall might see something I did not.
-
real sorry to hear that kelly, chin up!!
did you back the boards, or chase a ring on them?
i dont remember seeing that :)
-
They were quarter sawn boards I cut from a thin ringed stave. That stave had thin stuff I did not want to chase a ring a good one was deep so I tried something new.
-
Well lets go back to the basics.
60" stave the one on the right. Not a bad stave at all.
(http://i43.photobucket.com/albums/e383/gillk/Staves/20150111_150940_zpstahxao2t.jpg) (http://s43.photobucket.com/user/gillk/media/Staves/20150111_150940_zpstahxao2t.jpg.html)
Nice rings. ( chased down 2 more)

and thanks bue
-
the fades might wanna be longer almost how the top fade is in the pic above.
good luck mate- looks like a nice chunk of wood.
