Haha yeah it does get old but I kind of enjoy it. This past summer we had a all summer job where we had to sandblast then paint these huge 82' and 86' web joistes for steel building and we were able to get two of them done probably in a 9-10 hour period of straight blasting only break involved lunch break and filling up the pots.
There are two jobs I did... managing the pots which I made 10 bucks an hour and all I did was sit on my butt and turn a few pressure knobs and waited till the pot was empty to fill it up again. Or I could do the sandblasting for 15 an hour. Which for only being 14 at the time 15 bucks and hour was awesome. Even for the hard work. The only thing that got sore was my arms. We had to wake up at 5 every morning to go blast. that was the only hard part.
