Zur Zeit verwenden wir Emaille, um auf die Platte zu schreiben. Die Emaille wird mit Terpentin verdünnt. Die Mischung sollte wie Sirup werden. Der Sirup wird in einem Zeichenstift gefüllt. Dieser Stift wird oft zum Osterneiermalen verwendet.

This is not a paid promotion. This is a note for people who are interested in the gluing method with a vacuum pump.

A traditional clamping system for large laminations or large veneers can be very heavy and taking up a big chunk of space. Fine furniture maker John Cameron recommended VacuPress in Maine. Ernie and I recently brought lamination samples there for a in person demo to learn how to properly glue stuff together with a vacuum pump.

The owner of VacuPress is Darryl Keil. His website is www.vacupress.com. Darryl discovered this vacuum gluing method by drying his own hiking food over 35 years ago. Since then, he has been inventing, experimenting, failing, and succeeding in this field.

The base board in the vacuum bag has channels routed for air to escape. The laminations or veneers and its furniture sit on top of the base board in the vacuum bag. A hose goes through the bag into the base board. The middle picture is Darryl dry fitting.

Die Ravioli sind Polster unter den Klavierpedalen. Sie können das Geräusch der Pedale reduzieren. Die können wir selbst herstellen.

These notes are reviewed today while installing damper heads in the piano. Some of them are learned from Bechstein Factory. Some of them are from my boss Jude Reveley. Some of them are learned from my own failures.

This is a short note about Ms. Blüthner's rebuilding process. She was born in the 1880s. Our shop is fortunate to have her rehauled from action, soundboard to refinishing. The refinishing job is down by Maggio Custom Refinishing:

The old slotted screws are of very good quality, worth cleaning and polishing. The hardware stores sell mainly Philips crews and those with all different types of heads, but slotted. The resurfacing method here is taught by Mr. Jude Reveley, shop owner of Absolute Piano Restoration.

When the hammer top hits all strings of one note at the same time, the maximum power is transferred. To make the adjustment, the action must have been finely regulated and the piano freshly tuned. The cheekblocks are better in place to make sure the action is at the correct position. This hammer to string mating process is learned from Mr. Eric Schandall. 

This is a figured-out-by-self note after all sorts of failures and damages. I do wish to learn how factories and other workshops offset the wires by the plate strut. What damages have been made? All that one can think of.
(German practice on the first paragraph: Diese Methode habe ich selbst herausgefunden. Ich möchte gerne erfahren was die Manufakturen und die andere Werkstätten machen. Ich habe so viele Teile zerstört, die man sich vorstellen kann.)

When pressing the sustain pedal, the dampers shall rise at the same time as a union. This timing adjustment method is from David Betts. Usually the process takes 1-2 hours when the dampers, wires, and regulation are in decent shape.

It all starts from nightmares that the damper system was put in wrong, or the parts were broken in pieces, and there were dust in the package where worms crawled everywhere eating and chewing happy.

​We try our best to replicate the backaction exactly as the original unless where were flaws in the old system. Every screw hole has to be marked and drilled precisely and spaced evenly. Usually music, podcast, or any distractions are banned for the day. The assembly process takes about 8 hours. This is a Renner Backaction. The assembly training material can be found on the Renner USA website :

Jude, the shop owner, uses several species of softwood for ribs. One piano usually has two kinds depends on the area, load, and more. After his calculation of ribs on each piano, we start the milling process. Each time of milling is a new practice. And each time is nerve racking to make it right, or almost right.

The year of 2024 is another year of learning, failing, learning, failing, etc. Two steps forward, one step back, sometimes many steps back. Some piano skills are improved and some woodworking skills have just started. 

Having been working around pianos for 8 years, I barely thought about honing the hand woodworking skill. Most of the job is done by machine, routers, plane, jointer, drills, sander, etc. 

​A few years ago, I came to a new tuning customer's furniture workshop to tune his piano, an old, beat up, dusty Baldwin grand. There were all sort of wood, veneers, hand tools, you name it. Somehow after tuning, we started a conversation. He showed me the new Chinese Ming Dynasty table that he just made a model of.
