HHB Pyramid/reflex design

[Robert Pougnier]

I thought I would post one of my favorite bows.

I build this one a few years ago. Originally tillered to 45# @ 28".

After several years of shooting and several thousand shots, it developed only 1" of string follow. I recently gave the belly a new heat treat and reflexed the last 4 inches by 1 1/2 " using dry heat. Poundage increased to 50# and string follow after about 250 shots fell to zero.

It's a stable a smooth shooter and with the right arrows I've had tight groups at 60 feet. I love this bow, particularly the worm patterns that were hiding underneath the cambium.

Nice bow did you Mean to whip the ends. That’s what I see in the full. Draw pic.

Thanks! I did indeed. My pyramid flat bows usually come out a little whip ended. I don't think that is unusual for that design. TBB talks about that in the sections on design/performance and tiller profiles.

I believe that by reflexing the tips I've asked the outer limbs to bend more. The near handle wood and midlimb are very wide and very flat, but since this bow has been a real steady shooter I did not want to retiller it and lose extra poundage after i reflexed it. I'm sure the bow could be more efficient with mass distribution but it shoots great so it does not bother me.

Here's a shot before I retinkered with it. You'll see it's already slightly whip tillered here. At this stage it had already been shot in over 2000x and had only 1" of follow, which I would call great.
