This is my new rubber powered pistol crossbow I made out of solid beech (10€ total).
Don't try this at home! slingshots, crossbows, pistols and tools are dangerous!
Rubber: Thera Tube Blue. Use Google Search.
Darts/bolts/arrows: commercially made. "pistol crossbow bolts" Use Google Search.
It deliveres a muzzle energy of 13 joules which is double the energy of pellet guns legal in Germany. The video shows how I constructed this small but powerful shooter.
