What type of tiller profile?
« on: April 21, 2012, 12:35:35 pm »
I am currently working on an osage bow that is parallel for half of the limb and them pyramids to the tips. What type of tiller profile should it have? Elliptical,circle or a combo of both?  I know that parallel limbs will produce an elliptical tiller profile while pyramid style produces the arc of the circle. Considering that this one incorporates both on the limb I am unsure what a good tiller should look like. Thanks in advance.   Danny

Elliptical

This ash bow matches your profile to a "t".

Mildly elliptical!
Stiffer than a true pyramid out of the handle, gradually bending more as you get towards mid limb then keeping that bend toward the tips.

Thanks for the feedback fellas. I looked at my side profile a little more and its more like parallel 1/3 and pyramid the rest of the way. It has some rollercoaster to the back. I have never tillered elliptical as all my bows previously have been pyramid or mostly so anyways. I may post pics when I'm done. I got it to 19" yesterday and should be able to get it the 27"@ 50  I'm shooting for today.   Danny
