Straight bow, optimal tiller profile (VirtualBow)?

(1/4) > >>

Tuomo:
Primitive archery is a great practical hobby – I have just finished a bow. However, it is also nice sometimes to be more theoretical and play with a computer and VirtualBow…

Here is a small comparison: just a straight bow with a very optimized front profile. I simulated nine different constant taper rates (from −0.006 to 0.010) to see how they affect the bow’s stress and performance. In your opinion, what is the "best" and most optimal full-draw profile? How would you tiller your bow?

Threy Cameron:
Interesting question.

I'd have to go with number 3 as I'm not a fan of whip tillering at all, really dislike how it looks and feels.
I've found stiffer outer limbs especially when Eiffel towered like in your depiction are much better when left stiffer and barely working.
Additionally I've found whip tillered tips to reduce early draw weight and lower performance and arrow speed though this is with my limited testing
and admittedly biased perspective.

The performance aside durability wise it'd be safer to have the widest part of the bow bending more and storing the most energy. 

I'm sure there are situations like the deflexed willow bow tips in some native American tribes where whip tillering is more advantageous
but for hunting use I believe they'd only be a negative.

That's a great program you've used for simulating the bows draw, would you mind sharing what program you used?

Cheers

Tuomo:
Great thoughts! You clearly know what you’re talking about. I’m using this program—it’s free and still being actively developed (current version 0.9.1, version 0.10 is coming soon and maybe the final version 1.0 is coming next year).

3 or 4 for me, probable prefer 3. Both are how I try to tiller mine. :) don't always come out that way because of the character of the wood I most of the time am using but that is what I am going for.  :)
