glass r/d longbow taper question

[Hermann From Bavaria]

hey guys,

a friend and me are planning a new r/d glass-longbow. it´s a mild r/d profile, and its 62" ntn. now i´m thinking about the taper rates. what do you guys think?

thank you for help

Hi Hermann,
i think a total taper of 0.004 is a good point to start. I have built a couple mild d/r-longbows like that and they all came out nicely. They bend nice and there is just a little bit of reflex left when the bow is strung.

I'm gonna try a total taper of 0.005 on the next one, because somebody asked me if i could build her a bow according to the FITA rules. That is no visible reflex in the limbs when the bow is strung.

This one has .003 total,1 -.002 and 1 -.001(belly) 64" d/r, 18" riser 1 7/16" wide  at fades

 

 

With a mild r/d, .004 will work, especially if it is narrow limbed,like 1.25" at fades.

Keep good notes,they are very good to have next time!

Andy, let us know how that one works!!

Personally .002 for a mild r/d works great.  I also add a power lam to 4" past the fade outs.  it shortens up the working limb and still has enough umph to move a heavy arrow.  Its all about experimentation.  dont expect the first one to be exactly as you want it.  you might hit it just right though.  Take a good look a Kennym's r/d.  he's got a great design.

This one uses actionboo .004 taper. Got all my materials from Kenny M. Top quality

I dont like that much taper in shorter bows. I use .002 in bows that length. I have built some with all straight lambs with good results. Less taper will be smoother drawing.

thanks guy for your feedback.

the first one i´ll start with .003 i think. i´m curious about what happens...

It depends on the width. More taper the more narrow you go.
