1) It's got a laser
2) I painted the handle black
3) I'm feeling especially full of sh*t Today

This was based on Joerg's steel slingshot how to, as you will notice though I didn't have any steel box so I used some dog ends of aluminium bar. There's also a wrist brace as it's legal here, and a laser as it looked cool, not sure how useful it will prove to be. The rubber attachment point is also forward of the handle for some extra power

Again thanks to Joerg for the info on rubber and attachment techniques, I'm using green thera tube and pulling back to 430%. So far I've only shot some dodgy berries I found growing on a bush in the garden but I'm thinking about making some lead balls soon.
