Pyramid vs Flatbow

[Jim Davis]

The definitive science on bow design was done back in the 1930s by Paul Klosteg and Clarence Hickman. It's all in "Archery, the Technical Side." It's kind of overwhelming math and physics at times, for me at least. But we're just reinventing the bow when we try to sort it out from scratch.

Klopsteg was a brilliant engineer who did secret and very technically advanced work for the U.S. during WWII. He was also an avid archer and bowhunter. He did lots of experimenting with arrows, bows, accuracy and related issues.

Get the book if you can.

the  TBB2 reference George cited, is indeed a good explanation of the tiller profiles obtained with pyramid or parallel limbs. Of course the tillers presume straight tapers combined with a constant thickness (or width as the case may be)

Jax started this thread asking which was the easiest to tiller, and I apologize to Jax for morphing the question to
"which tiller is better for what?"

I think that a pyramid is easier to tiller jmho

[George Tsoukalas]

I think so too but only of they are tillered properly which is more rounded than elliptically tillered. Otherwise you'll just get more set.
