tillering bow and it is torquing
« on: September 15, 2009, 10:00:00 PM »
I'm making my wife a target bow out of mtn maple and still in the tillering stage.  

When I pull back on the tillering string the bow wants to torque clockwise.  Does that mean the wood is stronger on the right side of the belly? It is a right handed bow (she will hold it in her left hand).

Any suggestions?   :)  

thanks, bow-guy

Is the bow on a tiller tree?
Do you have the handle shaped?
Are you still on the long string?

Thanks Dano,

After I scrap a little wood off I then pull the medium length tillering string back 20 times before putting on the tree.  That is when I noticed the bow torquing.  The handle is partially shaped.

Thanks,

Sounds like the string isn't centered, from what I can understand. What do you mean medium length string? Is the bow braced?

Are the tips lined up nice and proper?

Thanks guys,  I'll check for centered string and tips lineup when I get home tonight.

Dano, what I called a medium length tillering string is one that has very slight tension on it but not enough that you notice a bend in the limbs. Maybe I should call it braced? I really don't know.

Thanks for all the help and suggesitons!!

That's what we call the long string, one that fits loosely. Most guy's will go to a short string after the limbs bend evenly to about 8-10" draw. The short string could be used as the permanent string, you just want to make sure you don't brace the bow too high at first stinging, 3" brace height is good, Just enough to check string alignment. One of the easiest ways to miss your desired weight is to spend too much time on the long string, the weight isn't the same as short string. I don't mind helping, that's how I learned.

Remove wood from the other side of both limbs using a scraper. Check tiller frequently at short draws.  Jawge
