Title: Sneak preview/ need some help finishing!
Post by: Accipiter on January 07, 2014, 02:24:12 pm
OK, so I'm trying to replicate a rawhide sleeve take-down I saw here: http://paleoplanet69529.yuku.com/reply/303271/Re-Raw-Hide-Scarf-tube-take-down-red-oak-bow#.UsxBmrTWun5  (http://paleoplanet69529.yuku.com/reply/303271/Re-Raw-Hide-Scarf-tube-take-down-red-oak-bow#.UsxBmrTWun5)

Ingredients are some ocean spray billets, rawhide and hemp sting/bolts (I used 2 instead of 1, haven't cut them short yet).

Ain't it pretty? :laugh:

After I got it to floor tiller, I noticed the tips were not aligned, so I steamed each billet straight, bending each maybe 15 degree about 2/3 of the way out along the limb. Easy, right? Unfortunately, after some more tillering, stringing and heat treating, the tips are back to their old tricks, if not worse. String isn't even going over the handle, let alone the center of the handle. Anyways, is it safe to steam bend wood another time, especially after a heat treat? How can I make sure the alignment stays straight next time?

I really like this bow, the handle is staying together, tiller is looking pretty good so far and the poundage is right where I want it. String alignment, not so much. Help me save this one!

Any thoughts? Could I steam the tips and then heat treat them on the side to try and lock it in?

If your wood is dry now I wouldnt go back to steam any more the allignment doesnt look all that bad you can take it out with dry heat?

I'd just use crisco and dry heat. Also account for the spring back the wood will have. Take it a little farther than u need and it should come back a little.

How does the bow line up, tip to tip without the string on it?
  Those bolts are gonna be uncomfortable when shooting the bow.  ::)

Haha, no doubt Pat. Right now the tip alignment is good when unstrung, but I did do another round of steaming last night. Is there a way to make sure it stays straight when strung?

If the limbs are uneven thickness from side to side the bow will continue to pull to the side. Check the limb thickness and see if it is uneven.

Ok, that sounds like a good thing to check. Which side would it pull toward? The thinner one?

Yes   I place my thumb on top and fingers under and feel the thickness. Moving them across and along the bow will show you where the differences are.
