purple check BBO

[DirtyDan]

Here is my latest Bamboo-backed osage bow.  It is 66" long and pulls 56lbs. at 28".  It is reflex-deflexed and the riser is laminated purple heart and maple inlaid into black walnut.  The tips are made from the leftover wood from the riser.  It is a really sweet shooting bow and very fast, mostly due to the stiff bu narrow outer limbs.

Nice lookin bow, looks like it's doing all the work in the inner limbs tho.

Nice Dan. The checkered handle accent is cool looking. This is the second one like this in the last few days. Cool!   I agree with Dano. Need to get the mid limbs bending a bit more.

[DirtyDan]

Thanks, Dano and Pat;  I have disagree with both of you, however.  This design makes for extreme speed--similar to a Holmgaard--with stiff outer limbs. Try it sometime. The midlimbs are where most of the reflex occur, and if you tiller that backward bend out of them, you lose a great deal of poundage and thrust.

[Dano]

I'm familiar with the design. But if you focus on that left limb at the fade, that is where all the work is being done, the bow doesn't have that much reflex.
Whatever, just trying to be honest, I hate it when people say "oh that looks great" when it don't.

To me all R/D bows look funny at full draw. They look like the entire limb doesn't share the load. I prefer to see the circular tiller of a selfbow. From seeing other bows you make Dan, I'm not questioning your abilities, just not my thing.

Dirty,

I did quite a few R/D bows lately, but as far as I can judge from the pics, I must agree with Dano. I'm afraid you overcompensated the r/d in the bow.

But, I can't tell enough from the pictures, As the amount of R/D in your bow is hard to see from the picture.

better pictures might proove you're right. They'll need a uniform background, and should be taken at a correct angle.

I'm not questioning Dan's abilities either, just sayin what I see.

[DirtyDan]

Gotcha.  Thanks guys.  No offense taken.  Just trying to perfect this business.  All I know is that this design works for me and I have made quite a few of these for others, and they seem to like the performance.  I have tillered some of these to perfect round, and they don't seem to perform as well.  But, if you like the perfect round, that is your cup of tea.

[dutchwarbow]

hohoho Dirtydan!!

guess you misunderstood me. This tiller would've been perfect if only the R/D would be a little more radical, wich it might be, but it looks less extreme in the unstrung picture.

these bows are indeed extremely well performing

If I were you I would narrow the last 6in to foot from it's current width tapering down to 3/8 or 1/4. If you go down to 1/4in you just have to use backnocks. You do want the outer limb to be stiffer in this style of bow but it isn't bending at all so you could go narrower(in width not thickness) just enough that if barley bends.

Nice one Dan.

This design makes for extreme speed--similar to a Holmgaard--with stiff outer limbs.

Holmegaard IS bending on the outer limbs.. You have 2/3 of the limb not bending at all, and thats too much to make an effective HG-similar bow. Look at this pics
     
This bow WAS a perfect HG:) He shoot 370 meters 9/14 thisyear (Norwegian FlightChampion)

[dutchwarbow]

moen, I must disagree. The outterlimbs of this bow are reflexed, so they do bend. jut a litte too little  

guess the comparisation he made was the stringangle, not the bending proportions.

Kviljo's bow is one of it's class indeed. Gotto try one of those. But why the glasses? because he's afraid that the arrow explodes into his eye?

or because of the breaking string?  :p

[Moen]

Sorry, i dont see the first photo. Correction.. Bent tooo litle:) What I meant, was from brased to full draw...

On the first day, Kviljo get a compression marks on the bow. And as you can see.. The bow died day after!

One more thing and then I will let you guys alone.  The outer limbs are bending from about three inches of reflex to straight.  When the reflex is glued in--as it is here--a tremendous amount of torque is required to bring that reflexed limb back to straight.  Stress is registered all along the limb except the last six inches or so.  When released, the reflex comes back to straight with a great deal of extra force. The inner limb is in no way the only part doing the work here.
