This past week, I started my apprenticeship. On Monday, I worked on a 1920's Mason and on Tuesday, I worked on a 1900's Steinway. In both cases I took off the old action parts and put on new ones. This included the repititions and the hammers. I got to put in the strips of paper to control travel and I got to move the repititions to line up the knuckles. It was really cool work and the time went by quickly.
