I've done that just using the piano bench and a couple phone books. Make sure the leg bolt nuts are tight. Customer helped me lift it up while we slid phone books under the key bed. It's only on there for a few minutes. Another experienced tech told me he'd done it that way many times. Swapped the front legs, which made the key block screws accessible, and thus the action removable. --David Nereson, RPT
