Bows / The best shape for a reflexed bow?
« Last post by Tuomo on Today at 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

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?

More pics

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

The craftsmanship is great but I fell that the length is making to much mass for the draw weight.

After sealing the back weighing the bow then put it in the house for 24 hrs it lost 1 tenth of an oz. so time will tell what it’s going to do.

Ya it’s shaping up!   Looks like your classic brace there.  Should be a very nice bow for flight with those numbers.  I know you like the early draw weight.   Very interested to see what it might do in flight.  Keep us posted.

   Excellent, you have a flite bow there!
  BL checked the lowest in hysterisis of all woods as long as it didn't chrysal, it is probably the fastest wood I know of. You could use it in regular flight on friday and then tiller it down to 50 at 28 for broadhead on sunday.

Ok, its end of the year folks. Im going to make this post in multiple places where its appropriate. This is the last month to qualify for the first annual giveaway. I want to boost participation by including every entry into the December bow of the month contest, as an additional entrant into this drawing. So, if you are making a bow, or finishing one up, make a post telling about the bow build and post it up for the Dec BOM contest. If you want to join in financially, that would also be very appreciated, $20 will qualify you as well and help financially support this forum.
