D/R limb angle?

[monterey]

I'm working on a design for a mild D/R bow that will be 62 - 64 inch NTN.

My question is, what would be a good limb angle coming off the riser?

kennym's template   ?

[monterey]

I have that somewhere.  I'll try to print it and lay it over where I'm at now.  Building off Kenny's template has been an option all along and that might still be the direction taken.  

I do enjoy playing with design though.

I think it depends on how much reflex you put in her. I like to lay out so the nocks are 1.5 to 2" ahead of the riser back. Gives some preload to cut vibration and adds a bit of speed.

JMHO

Hard to improve on Kenny's design I reckon.

I use 10 degrees, and have seen lots of folks use 11.  I tried 8 but didnt like it.

[monterey]

Down to five variations from 60" to 66".  One is at 8 deg and the others at 12 deg.  I'm favoring the 12's at this point.  The 8 might make a nice longer 66" but I'm looking more towards a 60 to 64.

I'll try to do a picture.

I don`t meat to hijack the thread, but since bigbob2 said it`s hard to improve Kenny`s design, I want to ask someting.
I realy like Kenny`s design but I also like the tips to show some of that reflex when braced and when drawn. Kenny`s design dosn`t have that, the limbs look pretty straight and the reflex is uncoiled when braced. So, how do I achive the shape I`m looking for and does is improve the design in any way (or should I just stick to kenny`s shape?)
Thanks.

If you use less taper it will straighten out less at end of limbs, but that bends it more towards fades. I would def use a power lam if you go to less taper.

Or you could add some deflex to tips.....

Here are braced and unbraced picture of the last bow i built where I added a 10" .006" per inch tip wedge. It held the reflex well. The limb has a .003" inch per inch taper. So you might try adding a tip wedge.

WOW, that is a superbe looking bow Ben.
That`s exactly the look I`m looking for. I`m wondering if besides good look it also help performence (as far as I know, having stiff and narrow tips helps...).

[BenBow]

Here's the fd curve, speed, and performance info. It was a very smooth bow and drew 43.4 lbs. Once the draw weight gets above 50# the performance increases. A 67# bow produced 188 fps with a 675 gr arrow. I'm getting started on modifying the riser to make it leaner and build the limbs into the riser more. Just trying to get it to be more 1-piece looking. The pad angle on this riser is 10 degrees.

Kenny and Ben, all good stuff.  Thanks!

What I found on the KM design was my 58-60 form is plenty long enough to get 62 in.bow off it and that with a tip edge really helped hold some reflex in the tips.

[monterey]

You guys have me pretty well convinced to go with tip wedges.

[monterey]

Not sure how this is going to show up, but here are the five I've worked up.  Any thoughts, critiques, etc. Don't spare me, I'm thick skinned.

Benbow, That looks great, I have never used 10 inches but have used 8 inch wedges for years. Pretty much looks the same and gives you a longer draw with less stack and way better string angle. Win Win. I use a .060 wedge tapering to 0 so just about the same but not as long.
God bless, Steve

Mike it's hard to see the image but I lean towards a moderate profile and use power lams and/or tip wedges to shorten the working limb and move it towards the middle of the limb. The more radical the d/r the more suceptable it becomes to limb twist.
