Here's our starting profile for session 4 My goal this session is to get our tiller evened out and hopefully still make weight:
After some careful scraping on the top limb (right)I have a 3/16 negative tiller. The string alignment seems to favor the bottom limb up and the tiller is leaning the same direction so I'm going to go with it. the left limb is now officially my top limb... Just when I got Dano unconfused....Sorry Dano :D :
Here she is pulling 38#@26". Looks like I missed weight by a little. She kind of hits a wall at full draw due to the string angle:
And here's our finished session 4 profile:
Lessons learned:
For an Osage bow this short with a low target draw weight I'd make the limbs a little narrower next time. On a heavier bow you would still have enough thickness to keep the tillering relatively easy. With this bow my limbs finished out much thinner than I'm used to. The rule is twice as wide twice as strong but twice as thick 8 times as strong. So when you have thin limbs just a few shavings make a bigger difference.
Bow limbs run out of bend when the string angle hits around 90 degrees.... If you want to hit 27 or 28" on a short bow like this you need to flip the tips to keep the string angle down.
