tillering a bow long

(1/3) > >>

possum:
I'm working on a black locust bow.  It is 72" long, 1 1/4 wide at fades.  I draw 26".  I was wondering how you would tiller it knowing there's a good chance you will shorten it.  If I tiller it now with the last 6" not bending but then shorten 4" won't that just make it the last two inches not bending or will narrowing the tips cause that 2x4 effect where it will get stiffer?  I love the BL wood and this is the last piece I have.  Also, what are the options s far as draw weight with the width I have at 72" and at , let's say 68"?

I would just tiller it normally, the pike it, and this would result in pretty good tiller, but the draw weight will be higher.

I agree with Sean. Build it to the longer lentgth then pike it and retiller to the weight you want. Heck I would shoot it a bit at the longer length for a while. That way it will take the set and be broken in when you retiller it. I have heard thats what was done with english longbows. I've done it once before but was using some cheap wood I got a hold of and cant really determine from that what happens. Best I can say is go for it and see what happens!

Sean is right- tiller it normally, though avoid having it too stiff near the handle, and stiff tips won't be as big as a problem.

Justin Snyder:
If you want a 72" bow tiller that sucker to the weight you want and leave it.  If you want a 68" bow, cut the sucker now and tiller it to the weight you want.  Why mess around with all the extra length if you don't want it when done.  Lets say you tiller it to 60#@72".  You pike it 4" to 68" and the weight will go up to around 78#.  You will wind up tillering the bow again anyway.   Cut it now and tiller it once.  Justin
