Tillering help please!! Uh OH!

[adam]

Hey Guys,
    I'm working on this bbo and everything was going good until i started tillering. My left limb looks good but i can't seem to figure out my right limb. I've been using a scraper to remove wood out of the fade but it doesn't seem to be helping. I'm hoping some of you guys can help me out on this one! Thanks

Will you post a pic of the bow unbraced? What are the dimensions?
  R/D bows can be difficult to tiller. Are you exercising the limbs after wood removal?
 Also I prefer a single block for my bow handle to rest on on the tiller tree. The way you have yours the bow is resting unevenly and you won't get an accurate reading I don't believe.

Here is an unbraced photo. Right now the bow is 64" ntn 1.5" wide tapering to .5" nocks. I'm shooting for 50-55#. I tried the single block but i couldn't get the bow to balance on a single block. I guess i'll have to play around until i find something that works. I believe the stiff limb is on the left in this picture. I can take it the other way if needed.

How does one limb thickness compare with the other. The limb on the left looks thicker in the pic. That could be an optical illusion though.
   This is the main reason I don't form the handle until last. If it were blocky it would rest on the block better or it can be clamped without harming the finished handle. It doesn't need to be shaped until the very last.
  From looking at the unbraced pic I can see no reason why one limb would bend and the other not, unless it is thicker than the other.

Keep scraping,it'll start bending sooner or later.Take your time and like Pat said,exercise the limbs a good 30 pulls each time after wood removal.I've run into this many times where one limb is more stubborn than the other. Good luck.

Adam, that looks like a tough bow to make for the first timer. Short answer is the left limb is bending more than the right so the left is weaker. My advice is work on a straight stave bow. Jawge

[George Tsoukalas]

What kind of stave is that?

[Roy Steele]

Wood is wood and as Bowmaker saids.Keep scraping it will ben what else can you or the limb do.So what if one limbs thicker than the other.It's a wooden bow.This has happen to me quite a few times before.Theres always differences somewhere in wooden limbs on the same bow.No to limbs are ever the same when it comes to wooden bows.This is why you have a tillering board.If you want even build a lam bow.Remember wood is wood.

 Dead is dead no matter how fast your arrow gets there.

Thanks for the info guys! If anything the left limb is thinner than the right b/c i've been working it more. I'm sure it will get there some time. Like you said wood is wood all bows are different. This is the 3rd one i built like this and all have had different issues. But thanks again for the advice!

adam, I am no expert, made about half dozen bbo and I seem to have different problems with each one. You may want to consider leaving the limb alone at the fade out it seems to be very stiff (Straight) pass the fade out to the tip. If you take too much more off at the fade out you may end up with a hing there.

You are not the only one who struggles with a good tiller :-).

Well guys this one didn't make it. So exploded on me tonight after doing some more tillering. No one was hurt so thats good! Just need to start another one now. Thanks again!

Why did it blow? got pics?  you can learn a lot from a broke bow. I rarely discard them and study the breaks for insight.
