85lb Osage Selfbow Layout?

(1/2) > >>

cool_98_555:
Hello everyone.  I have a beautiful straight osage stave that I can't wait to get started on.  My draw length is 30" and I am aiming for a minimum of 85lbs.  Please note that I am not looking to adhere to the strict rules of the ELB with the rounded belly design in the D shaped cross section.  I am looking at a flatbow design.  I use 30" arrow shafts and I draw the full length of the arrow.  Right now my favorite bow is a 75lb hickory sapwood selfbow made out of a board that is 60" and can be drawn to my 30" draw length but with a bit of finger pinch.  I have thought about the layout for this bow and I have come up with some proposed dimensions for it:

1) Length tip to tip:  70" ( I would like to go shorter if I can, but I want to accomodate for the 30" draw, so I am open to 70")
2)Handle section:  4" (1" above center, 3" below center)
3)Length of fades from handle:  1.5"
4)Width of limbs at fades:  1.5"  (I think 1.75" would be sluggish in this design, but many have told me that wider limbs were good for osage selfbows in flatbow designs)
5)Taper: 1.5" at fades, taper to 1.25" at midlimb, taper to .5" at tips.
6)Thickness:  5/8" parallel limb thickness for starters
7)Arrow shelf will be cut into riser, preferably center-shot.

Knowing my draw length at 30" and my desired minimum draw weight of 85lbs, I am most curious as to the length of the bow, width of the limbs at the fades, and taper design I should be looking at here.  Any suggestions for these dimensions in particular would be very much appreciated!  Thank you!

You want to shoot an 85#@30" flatbow? What do you want to shoot at? What are your plans for it?

Newindian:
There is a lot there I can't comment on, but I would defiantly say lose the shelf

adb:
I totally agree.

I say make the bow however you like your bow, it's your bow, you should make it how you like it. That said, I think with your designs you could go a good deal shorter and still make 30". I would also go with at least 1 3/4" fades, unless it is some good dense osage. You might end up with somewhat of an oval cross section which ain't too bad of a thing really.
