Working dimensions for a paddle bow:
* 1-1/8 to 1-1/4" wide, 4-5" long handle
* Limbs are "spindle" shaped",
2.5" to 3.5" wide half way between fade and
nock, tapering to 3/8" pin nocks
* Limb thickness 1/4" to 3/8", sinew backed
* Length 42"- 46" tip to tip
* Draw length -- 22"-24"
Originals were almost invariably sinew backed. They were designed for hunting in THICK foliage at SHORT distances, often from a sitting position and drawn to the chest or bow arm shoulder.
If you make a bow more than 48" long, it's a Flat Bow, not a Paddle Bow regardless of the 'hourglass' shape of the limbs.
If you make the bow for more than 24" draw it's a Flat Bow not a Paddle Bow.
