Horn crossbow?

[BowEd]

A good 1/8" thick bamboo?

[Selfbowman]

3/16 at point 1/4 at fades. Gets thicker with width

One limb close glue the other up tonight.

I think you got this Arvin. I like the design

Mass theory?

[Selfbowman]

Can’t do this with whole bow but I weighed the two limbs and they weighed the same 8oz. Going to do the same with the cross bow limbs. Ok guys going technical here.😳ya Arvin technical! 😁 ok both crossbow limbs at this untillered stage weighs 18oz. 9oz each  but remember I only have 19” limb including the 3-1/2” bolt on portion. Will revisit after tiller. Yes I used a caliber at about four inch intervals on limb width . I will check in thickness after tiller and maybe during. Arvin

This is pretty cool!

[bownarra]

Interesting stuff.
How are you going to attach the limbs to the 'riser'?

[BowEd]

Cool Arvin.The plan is coming together.I'm going to guess it'll be 50#'s @ 18".The mass theory is out the window with this project I'm afraid.
I've got a buddy who likes making FG take down bows.He experiments with all different types of angles on his risers.
After tillering the limbs even it could be that you make a few different risers for it that it will change the poundage.Just a thought.
Might not make much of a difference though.
This project could go on and on.Maybe add a little sinew.....Ha Ha.

Limb caps

Ed I am going for 140-170 # . The boo will determine. I think I am going to trace the limbs on the tiller tree and if set stars to show  stop. Don’t know what weight that will be but another tiller learning experience . I think laminated horn might make it perform better but that’s another day.Arvin

Top overlays tonight. Starting to come together on the  limbs.
