Around the Campfire / Re: What Did You Do Today?
« Last post by Eric Krewson on December 07, 2025, 09:15:28 am »I finished up cutting up the small deer I killed a few days ago, I had a little more than 30# of boned out meat not counting the ribs. I vacuum pack everything, with what I have left in the freezer from last year, I am in good shape until next year's season.
I have a friend that wants a deer, any I kill after that will go to hunters feeding the hungry if I can't find someone that wants one.

Bows / The best shape for a reflexed bow?
« Last post by Tuomo on December 07, 2025, 08:53:17 am »What is the best shape for a reflexed bow? I experimented with the VirtualBow program to search for an answer. Shown here are five different reflexed designs, with a straight bow included for reference. All of the reflexed bows share the following characteristics:
* Length: 66", brace height: 6", draw length: 28"
* Draw weight: 50#
* Identical front profile, optimized for even stress distribution along the limbs.
* Taper rate 0.008
* Three-layer construction; only the core thickness is adjusted to achieve the 50# draw weight
* All reflexed designs have the tips reflexed by 100 mm (4"), measured from the belly side of the handle
* 10 grains per lbs -arrow
So, which shape is the best? By best, I mean the fastest and the one that stores the most energy. Why? Which design performs the worst, and why?
* Length: 66", brace height: 6", draw length: 28"

That bend profile on those limbs looks a lot like a BL bow I was working on several years ago. I had to abandon it because it was too unstable
I have a question Mark, maybe a couple of questions. What amount of reflex did you finally settle on as being optimum for your designs? By reflex, I mean how far behind the back of the bow were the tips.
The bow I was working on had a deflex handle profile like I normally make them and the tips were set back several inches. Unfortunately I don't have pictures, or if I did I can't find them
