It's been about three weeks since I started work on this Steinway K-52. There are a few reasons why it took so long, but after two jobs coupled with the difficulty of working on these particular models, it can take longer than expected.
Regardless of time and effort, here we see one of the final stages of regulation; key leveling.
The final stages are somewhat arduous, yet at my level of technical skill (over 75 uprights and a few grands fully regulated!) the process is quite quick.
If you're unsure of what regulation is, see this link here:
This is one of my most important tool boxes. The colored "donut" shaped rings are named "punchings" which aid in the leveling of keys as well as the regulation of key dip (a.k.a. how deep the front of the piano key moves when pressed by a finger). There are many different tools inside this tool box, but the punchings are a technician's best friend, for they can be used for many different applications when fixing a piano.
A first person view of key leveling. This is what I see when leveling all of the natural keys on either an upright or grand piano.
The final procedure! Enjoy my pride of three weeks of intermitted work!
This video was recorded by my friend and local soul/r&b artist, Jarrod Lawson. He's not too fond of the K52... "Eff the K-52!" Most technicians would tend to agree, to be honest. This particular model is known to be one of the toughest pianos in the world to tune. This is quite the opinion, but still a general knowledge among piano technicians...
