Piano set ups and regulation

This is the procedure followed by our piano workshop technicians.

1 Setting the hammer blow

2 Checking depth of touch

3 regulating let-off

4 Levelling keys

5 Setting back-checks

6 Setting the half-blow

7 Checking damper engagement is halfway down the key-drop.

8.Checking damper strength. (Some pianos require changing the damper spring strength. In order to make the damping very precise some manufacturers will use over-strength springs. This has a detrimental effect on the touch.)

 The weighting of the key (the touch), has 3 distinct progressions.

a. Down-weight to lift hammer (48grams)

b. Down-weight to lift damper

c. Up-weight after blow completion.

We would be content when those measurements are close to those on a concert Steinway grand!

9. Tuning and toning piano

10 Checking casework for squeaks and creaks.
