Tillering problem

<< < (2/2)

toomanyknots:
Ya thats normal for reflexed staves while long string tillering. If it does it while braced, well, then thats a totally matter... I have to have my a helper too to hold the handle until it is bent enough on the tiller to not flip.

DCM4:
It's called lateral stability, or more precisely the lack of it.  The bow wants to rotate on it's lenght axis because the string is pulling off center.  Be sure your string grooves are cut evenly, and that the limb(s) don't have twist.  Staying to center line is important on long, narrow bows.

Kviljo:
With such bows I firstly make sure it is wider than it is thick, and that the center line is good. Then I give it a good floor tiller, and simply pull it to near brace while gripping the bow on the tiller. If it is still unstable at brace, I usually reduce the thickness to make it more stable. Reduced draw weight traded for stability is usually better than a broken bow. Leaving it braced in a jig for some hours may also help get rid of some reflex, to make it more stable. - just make sure the tiller is fairly good before doing that, to avoid hinges.

keef:
Thank you for all the replies.. Really helpful.

I now have this bow ready for long string tillering, and the problem is solved

Now to make it into a bow!!

Will of course post my results (Good or bad!)

Thanks again
