Character Osage Build - Now a Takedown - Finished!

Well, I put the bow on my tillering setup and 2 things were instantly apparent.  One, is that I'm waay too heavy yet; and two, trying to pull the bow imposes a significant sideways torque on the handle.  I've always used a loop of rope to hold the bow under a bow scale and that does not work with this one.  I'm going to have to create a different attachment approach (which I should do anyway).  I'm happy that the bow is still so heavy, I'll be able to take quite a bit off the limbs and make the bent part flow into the rest of the limb without a width change.  I had the camera with me, but I didn't get enough bending to show any tiller yet so I didn't shoot new pictures.

Well, this bow intimidated me so bad I ignored it for a couple months.  Tonight  I finally sucked it up and began to work again.  First I had to make a U-shaped clip to hold the bow on my bow scale for tillering without letting it twist.  Then, I started taking off wood.  The straight limb is normal tillering, the crooked limb is something totally different.  It was doing all its bending in the crook, so I treated that like a hinge and haven't touched it.  I took it very slow and at the end of the night I think it is bending enough to cut string nocks and make a string for it.  I don't have the string running through the handle so I fired up the heat gun and bent the straight limb a little.  In the morning I'll bend the other limb.  I still have a long way to go, it pulls 45 lbs at roughly brace height.  I didn't realize when I took the pictures that I wasn't pulling from the center of the bow.  For the purpose of getting a string on the bow I don't think it matters.  I think both limbs are too stiff in the tip, the crooked limb more than the straight limb.  There's a knot just outbound of the crook that's making it tricky.

wow great job so far, the tiller is coming a long nicely

gstoneberg:
Well, the bow broke today.  I was afraid it might when I started and it did not disappoint.  I had it tillered to about 26" so it was close.  I was pulling it trying to see how it was bending through the crook when it went "bang".  Interestingly, neither limb appeared to fail, it just got easier to draw.  I felt the failure in the lower limb but didn't find a thing wrong down there.  However, when I looked at the crook I discovered it had cracked clear through the bow, back to belly.    The crack is about 6" long and nearly centered in the limb.  It looks a little like a weather check when the bow is unstrung, but opens up when the bow is strung.





I did take one picture of it strung, but I didn't get any pictures drawing it.



I could glue the crack back shut and sinew back it, but my suspicion is that it wouldn't be that good a shooter and could still blow up in that crook.  I'll probably order a set of sleeves, cut the bow just north of the handle and build another limb to match the still good lower limb.  I have a sister stave to this one that is in the first picture of this build, it would be a good match.

maybe just wrap it and glue it then make it a bow with short draw?
