Straight bow, optimal tiller profile (VirtualBow)?

<< < (3/4) > >>

Zugul:
I'd say 4 or 5, even tho all my experience comes from reading this forum, watching bowyers on youtube and 10-ish broken bows  )-w(  (lol)

simk:
I'd maybe lengthen that powerlam by 6" and start a reverse taper 7" from the tip - then recheck  :)

the one that delivers the best theoretical arrowspeed at a stress level that does not compact the wood too much

by the numbers

Tuomo:
Here are clearly very experienced bowyers (and I already knew that…)! Number 4 is the best!

Here are the results I got from the program. It is clearly shown that the closer the bend is to the handle, the more energy the bow stores. Also, the more whip-tillered the bow is, the more efficient it becomes (the reason here being lower tip mass). Very interestingly, the speed is almost the same, independent of the tiller shape! It would be possible to say that every taper rate from −0.006 to 0.002 is good, so in that sense it does not really matter how you tiller.

Aussie Yeoman:
That's a really interesting result. Thank you for putting in the legwork and plotting it all out. I wonder how it would go comparing across different lengths of bow for the same draw force.

For me, I like anything from 1-5, with 3 or 4 being the sweet spot(s).
