--- Quote from: Robert Pougnier on February 19, 2026, 10:51:24 pm ---I've recently read something interesting, I don't know if it's relevant here and it sounds relatively risky anyhow:
Some flight archers shooting to break records will intentionally overdraw a lighter bow, say a 45# @ 28" drawn to 50# @ 30" (hypothetical numbers). Rather than shoot a bow that has been tillered to 50# @ 30# off the bat. I wish i could remember where i read this. It seems like a way to under build a bow on target for very dangerously low mass intentionally and squeeze the very most out of a flight bow. Maybe it also ensures compressive stress is kept to an absolute minimum prior to shooting.
Does this ring true or make sense?

Robert, thats 99% correct, at least to what I try to do when it all comes together. I will design a bow to pull 50@26, and tiller it out to be 44@24 and stop, never actually hitting 50 pounds ever on the scale. When it comes time to shoot the bow in flight, the ideal situation is the first time it ever hits 50 is at the weigh in, so its fresh. I make my arrow rest adjustable so that if its a little over and hits 50@25.5, I can move the rest to that position allowing my draw to be spot on.

Dave if you have a shelf how are you going to keep the bow together at the handle attachment? I must not understand what I’m seeing in the photos.

Ya Arvin the pics don’t show it clearly. It’s glued to the wood handle and then wrapped with strong cord. Artificial sinew actually. I’ll switch this up to flax cord later. Similar to my other boo bow builds like the one you have it’s also got the relief ramp at the end of the handle on both ends. I’ve got a 26” flight arrow to test out this bow to see how it does at 28” draw. I’ll try to post more pics.

here are some better pics of the handle Arvin.
on related note, i may have a solution to reach my 70lb target. the bow right now sits at 69"ntn. I could move my overlays inward 1/2-3/4" or so on each side and it wouldnt mess with my tiller too much and add just enough draw weight. I may try this in next couple days and see how it goes. With some work the bow did balance out fairly nicley so this may be a good option for me without having to start over.
superdav95:
Ok so I’ve popped off the horn overlays and moved them in an inch on both ends and reshaped them as before. We shall see where we are as far as any increase tomorrow. It’s now 67”ntn. I did loose a little reflex height as a result. It’s now just over 2”. I’ll get some projected draw numbers and update.
