The Next One
« on: August 14, 2010, 10:08:00 AM »
Ok guys, here's my latest bow. It's 58" long and draws 42@28. Basicly it's the same as my last, but i modified a few things on the design. First i made the limbs wider, because i had troubles with twisting limbs with the last one. Because i didn't want to go thinner with the stack i reduced the riser length about 1 1/2 inch. And finally i decided to build this one without tip wedges. I hoped that less mass in the tips would add speed and the draw would also get smother.

 

 

 

 

 

I don't have a chrono to measure the speed, but i shoot a few arrows on a target at a distance of 5 meters. With my mac i recorded the sound made while shooting. Then i compared the signal with my other bows and it's by far the fastest bow i have built so far. So it seems that the modifications i made improved the performance of the bow.

Come on!  More pictures!  I rarely take a fancy to a glass recurve, but that's just plain "perty!"  I love the lines on that bow; very graceful. Truly, if you have more pictures, lets see 'em!  Great work!    :)

What color is that riser action wood, and where have you been getting it from?

Thanks

thinking about it this bow kinda looks similar shakespeare super necedah in its riser shape. although this bow certainly puts my necedah to shame in colors and overall finish. much nicer curving limbs too. definitly a great job on those ones.

It seems to have allot of string resting on those recurves, that should make it shoot real quick.  Nice looking bow design and a great job.

It does indeed fling the arrows down with authority. On the downside the draw is pretty strong right from the beginning, but that also means that there is a lot of energy stored while drawing the bow.

For the next one i will increase the total taper from 0.002  to 0.004 to make the tips even a bit lighter. In my opinion that should make the draw a bit smoother and hopefully add even more speed.

Andy, great bow! Everyone perceives smooth draw differently. Sounds like you may prefer smooth in the begining of the draw and adding taper will give you that perception. It will tend to make it stack earlier nearing the end of the draw though, but that may not be a concern for you. Typically, less taper adds preload which implies more speed. So likewise adding taper may rob some speed and can make it picky with arrows particularly heavier ones.

Generally, if you add taper you may want to stiffen the tips. If you go with .004 and the tip wedges it seems like a good combo for performance. There are several 50's style recurves with that combo and they shoot great. It may get noodly at the tips and hard to fine tune if you don't have stiff enough tips with .004 on a recurve. It depends on how hard the curve is and you will surely need a parabolic width taper. If it gets too weak in the tips you can always add a belly overlay of glass and fade it out as it passes the curve into the working section of the limb. Tip weight means little if the curve opens too soon. Weak tip curves wobble badly when the string slams home.

I think you are right on increasing the taper to smooth out the draw but you will probably find that the tips will open up to much and to soon taking away speed with that much taper in a recurve- tip wedges might be an answer to that issue though.
