Monterey, I'm def no expert. I've only made four bows. But what I'm suggesting is a longer string and less brace height.
I built a 60" r/d for my boy with about the same reflex, but a bit more deflex. I didn't use any tip wedges, and it is braced about 6-3/4".
I've never done a draw force curve on it, but it's pretty smooth to 29-30"

The last third of the limb doesn't seem to be working much. Have you tried it without the tip wedge? That would increase the amount of working limb and would increase the draw length.

She looks like she is bending pretty good... I would say go to 62" but I think your limbs would be even straighter or even slightly recurved... I prefer a little bend in my limbs (D-shape)... I think it can make a bow quieter... What speed are you getting at 10gpp @ 28"draw?? If you are getting 180fps or more, Don't change a thing... What is your riser length from fade to fade??? Maybe a shorter riser with a power wedge may help... These are just suggestions or some things that I may try... Other experienced bowyers may have more definite answers for you...

You need to download a DFC spreadsheet... It is a lot easier than drawing it out...

Critter, This is the first off for this design and form so there is no reference to any other builds.

Now, help me with this cause we think differently in regards to the working of the limb. My thoughts are that without the wedges and bending more towards the ends of the limbs would have the tips coming around even further and thus approaching the 90 degree angle earlier in the draw which would make it stack sooner?¿?¿ [Confused]

Shredd, no speed reports at this point cause the riser Is not formed yet and it's not final tillered. I'm not sure how I'm going to do the riser and grip yet.

I have a spreadsheet. Probably the same one you have but it won't accept partial inch lengths for draw length. I'm still playing with it.

You may be right in regards to your design. Taper rate, limb profile, amount of relex , ect... all pays into it.
In my design I have a more radical reflex and tip wedges stiffened it to much and made it bend more mid limb. With my reflex it worked better without tip wedges and gave a more elliptical bend witch increased the DL capability.
Oh the joys of tweaking a new design!!!!!! Lol
Keep us updated with the progress

Critter, yeah, that's why I started this topic, to get as much opinion and thought as possible.

I can't tell you how much fun I've had with the part of your signature line that says "I went jackalope hunting but all I saw was does!"

When someone asks me what I went hunting for I throw that one out there. [Smile]

I think I would study that full draw pic(it's the one that counts,eh?) and trap that bow where I wanted more bend. Mostly in the middle... Then do a DFC again....

Stay sharp, Kenny.

There you go... That is some good advice... The only thing I would add to that is, Take lots of notes of how that bow is now... Shape the grip and get some arrow speeds before working the limb... And then compare speeds and shootabilty with new shaped limbs... Once you do something to those limbs, they are gone forever... So take those notes....

And don't forget to share what you learned with us... [Smile]

Alrighty then!

I'm going to proceed with the riser shaping and see where it's at and how it shoots and feels.

Already did, Roy. Probably wouldn't have gotten this far without him. [Confused]
