Sand blasting

So this is the sand blasting machine in sculpture. You wear massive industrial gloves and place your arms in the pink holes and look down in the small window, which as soon as you start blasting sand, you can no longer see through... To activate, use the pedal.

To set up, i laser cut onto a metal strip covered in sticky back plastic and removed the plastic where necessary.

I started with the aluminum strip. I did 5 passes and it turned out ok. I found perhaps more blasting was needed...

I did too many passes with the copper strip... the sticky back plastic blew off so my numbers were not visible any more.

To conclude, the affect made with this machine is nice but i feel accuracy may be impossible to achieve.
