Well I did it last week on the last span I had to shut down after working 10-14/7 days a week on the hammer killed my shoulder. Tendon problems I think. It was just a little sore if I wasn't running the hammer, but while hammering I couldn't stand the pain. They took me off it and brought in one of the leaver pullers to finish. I'm not sure what was more painful my shoulder or watch him running the hoe and finishing my job. I felt good the next day, but got chewed out when I hopped on the dozer they don't want me doing anything just "supervising". But it gave me time to take a few more pics, but I'm post them later the wife just got home.
