Title: board bow tiller
Post by: Dan Jones on March 28, 2018, 08:25:04 PM

I am working on a board bow. The lower limb is 1/8" greater than the upper limb. Unless I am mistaken, the reverse should be the case - the upper limb should be positive by the 1/8".  What do I do to this bow to get the upper limb positive, or at least get the limbs even?  I shot conventional one finger above, two below.  Thank you.

If you currently have negative tiller and you desire positive tiller you would need to weaken the upper limb.

That being said, are you to full brace and shooting the bow yet?  How does it shoot?

Are you tillering on a pulley system - where are you attaching to the string?

Many here do not tiller to a predetermined tiller measured at brace.  Tiller for equal limb timing.  Several posts on here with this discussion.  Try a search on it if your interested.  Roy has posted several videos too.

Thanks for the reply.  I am shooting the bow and it certainly seems okay with the tiller as it is.

You can shorten the lower limb by an inch to stiffen it. Before you do that post pics, braced, unbraced and full draw.
