smoothness on a scale of 1-10

how to discribe smoothness. the DFC tells all.
we use a scale of 1-10 to discribe our models
we dont just tell you "it's smoother than our last model" we actually put them on a chart. we state where each model sits. we don't tell you it's got bamboo therefor it's smooth. bamboo does nothing for the DFC. utterly NOTHING.
and I can tell you why.

Intéressant 😮

His HEX 9 are 1.29 ft lbs energy per lb of draw. A normal Olympic Recurve is around 1 ft lbs energy per lb of draw. He has gotten pretty far into compound bow territory for efficiency. Those max out at 1.4 ft lbs energy for 1 lb of draw. He has gotten really close without needing cams. Respect for nearly perfecting the artform.

@@musikSkool the highest prototype stored energy limb we have made peaked at 1.32se/pdf. We have also achieved 2.7lbs of letoff. The 1.32 was shootable, but letoff creates a issue I don't think is solvable under the guise of a recurve. The cams need synchronised with letoff

Interesting stuff - I'm all set to do some measuring.... A question... How do smoothness and draw force curves relate to how the energy is transferred to the arrow? Whilst I am drawing the bow, I get that the feeling changes based on the DFC of the bow and that different limbs can store more energy - but what do different DFC's do to an arrows flight - is there a related and derivable graph that indicates how the arrow accelerates, and does it even matter, except for imparting the maximum amount of energy into the arrow? Can different DFC's change an arrows trajectory - other than providing different arrow speed?

Thanks. This is quite interesting. I've been trying to understand why two bows I have feel differently for same full draw pounds. I think the better shooting one might stack less. Does stacking affect arrow dynamics?

[@BorderArcheryLTD]

Yes. Stack has hollow energy... I will try and do a better video soon

@@BorderArcheryLTD awesome. Thanks.

[@jameswhitaker1324]

Thanks! I actually understood a fair bit of that. I’m interested in finding a book that talks about the physics of various bows from long bow to recurve to compound. Do you have any recommendations?

@@jameswhitaker1324 not really... I fear they could be limited in thier efforts due to limitations in materials

@@BorderArcheryLTD Ok, that makes sense. Thank you for responding
