Something I've been building and playing with recently
A compound cross-bow done according to so called "paleo-legal" or "abo-legal" rules.
All wood. No glue , no metal.
Cables and string natural fiber - flax with cotton serving.
Juniper limbs , birch tiller, hawthorn cam levers.
All relevant shapes in wooden parts are designed in a way that could be reproduced using mesolithic tools- splitting,drilling,grinding,chiseling.
Draw weight and length is easily adjustable. For testing I've been mostly using 46 kg with 185mm stroke (~100#/7").
I have not had a chance to chrono this, but trajectory and penetration tests make it look reasonably fast for something made from backyard pruning waste.
Throws 0,7 g (11gr) piece of bbq stick appx couple hundred m/s (600-700fps) - that is 700 fps for 10 pounds per grain or so.
Trigger is Indo-Chinese style notch and lever.
Fun toy. Very air gun like ballistics.
Still a bit under construction. I have been testing various sight arrangements and other accessories.
