Hi everyone! First post to forum.
Im sorry, but i dont own any real slingshots, never even tried any. But in my childhood i allways build lazy projectile shooters from Lego bricks
Now in later days with engineering backround i made crossbow style brickshooter once again.
Im really proud for my achievement. Never ever imagined you can build something this powerful from plastic Lego bricks.
Here is facts about the gun:
- Crossbow style, include barrel roof, Not open rail.
- Pulleys at front, no crossbow limbs.
- 2040 Dankung tube power source. (1745 tube in order)
- Pump action, pulls ammo from clip. (15 ammos in magazine)
- approved projectile: 1x2 techic lego brick 0.82 grams https://www.bricklink.com/v2/catalog/catalogitem.page?P=3700#T=S&O={%22iconly%22:0}
- ~40 m/sec, 131fps
- Also shoot everything that fits in the barrell.
What is best way to improve projectile speed and accuracy even more?
Should i extend barrel = more draw length?
Maybe some other type of rubber? Only tubes area compatible.
What role front pulley diameter does?
I know it is not as powerful than real slingshots. But compared to my childhood, this is not a toy anymore. With sharp ammo it penetrates soda cans in 10 meters.
With blunt 1x2 bricks it shoots throught cardboard.
Have to try steel ammo sometimes.
I will post some pictures later.
