This let to K-bow
, wich works quite satisfactorily, but with 6 limbs and massive riser section it is uneconomical to build.
I soon found out that split limbs were not necessary, also got rid of the the backwards facing "cross-bow".
So after X-bow comes the Y-bow:
This makes a durable and lightweight construction as the limbs are separate bows holding their own tension. So the assembly only takes the final draw-weight.
Added pulleys to the arms out of tarpaulin buttons with acrylic cased stonewall nails as axis.
This allows twice as long power stroke
Accuracy is surprisingly good, arrows are going were they are pointed, despite limbs being badly off-balance.
Unlike the the usual backwards scorpyrd-daVinci bows, this is a true in-swinger. When triggered all moving parts collapse inwards and forwards. So this can be safely shot while in contact with users body or other obstacles on the flanks.
And the best part
F/D-curve is fat like a singing lady. This is a true compound bow.
Coming up next
- Limbs steamed to matching curvature
- Second set of pulleys for 50% longer power-stroke
- Trigger mechanism
- Stock & bolt rail
