After taking the piano all apart and doing a complete cleaning I ordered new key tops, leveled the keys, repinned some of the hammer flanges, regulated the action and put it all back together.
I have been taking instruction from a Registered Piano Technician (RPT). I am learning to tune, repair, and rebuild pianos. Here are some pictures of my first major overhaul. I have been tuning for a while but am delving into repair.
