Old technology meets new: Installing pedals on an upright piano

August 13th, 2017

While installing pedals on a 90 year old upright piano, I had the opportunity to upgrade materials, and have a little fun at the lathe. The old pivot system employed a hardwood dowel bushing in a cast iron bracket. The system was likely a good one for the first 30 years, but with wear, it became floppy and noisy, and broken. I chose to fabricate new bushings to be used in the old brackets using UHMW (ultra high molecular weight polyethylene) rod. UHMW is ideal for this application, since it is self-lubricating. For someone who doesn’t do a lot of lathe work, it presented a bit of a creative challenge, and I’m pleased with the result. I’m sure it will be serviceable for many years, and earns a lifetime guarantee.





Trimming Damper Heads

July 23rd, 2017

I wanted to trim 4 mm from Tokiwa damper heads for better geometry in a 1927 Leonard upright. Here’s the jig I built to get the job done.





Stieff Rebuild — June 2017

July 3rd, 2017

The soundboard was tapered (diaphramized in Steinway terminology).   First contour lines were routed into the board, and then the board was sanded to the contour lines on the stroke sander.

 

Profile of countour lines tapers the board from 0.26″ to 0.33″

The video shows use of the stroke sander to achieve the taper by sanding to the contour lines.

Ribs were shaped to a radius of 60 feet, then glued to the soundboard using cauls and compressed air clamping pressure.    The photo below shows the last rib in the cauls.  Typically I clamped 3 or 4 at a time.

After the ribs were glued, a radius was planed onto the ribs.   This is a craftsman touch.   Few will ever crawl under the piano to inspect this detail.





Steinway A-3

March 27th, 2017

The cobbler’s children go without shoes. But this piano technician is breaking out of that paradigm. New to my living room is a Steinway and Sons Model A-3 built in New York in 1922. After I completed three days of work on it, the piano is very pleasing to play. At some time, it will be completely rebuilt; but for now, it is a very nice “daily driver”, to borrow from classic car enthusiast lingo. That time will not come until the high-end restoration of the 6’3″ Charles Stieff (1911) is complete.

 





Stieff Rebuild – February 2017

February 28th, 2017

An update on the Rebuild of Stieff 28334 has been a long time in coming.   I’ve been disappointed with my inability to focus energy on the project!   But progress has been made.

Cauls for gluing ribs to soundboard.  Note the concave or convex shape for top and bottom cauls.  These are sixty foot radiuses.

Prior to working with the actual ($$) new sound board, a sound board mockup was prepared using inexpensive quarter-inch plywood.   This step was taken to work out the bugs in the system before working with the new spruce board.

For the mockup, I used some clear fir as ribs that was available at no cost.  The picture below shows a jig with a 60 foot radius for shaping the topside of the ribs.

Below, the mockup progressed with the ribs fitted to the frame.

The mockup continued by gluing “ribs” to “sound board”.  A few issues were noticed, and I was glad that I did this mockup, so I could proceed with confidence.  The cauls use mill hose pressurized at 30 psi.   I’m doing four at a time, and progressively moving cauls to a new position as glue dries.

Below is the completed “trial soundboard” which fit well when placed back in the frame.

The Good Work

April 26th, 2016

I paused for a moment in my work this morning to realize that I was doing exactly what I wanted to be doing.   Practicing the crafts of piano restoration fits me in such a fine way.   This morning I was doing key work on an 1880’s Knabe grand, and while I applied my skill to restoration, I could pause to admire the work of craftsmen from 130 years ago.

James Michener is credited with the following:

The master in the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his information and his recreation, his love and his religion. He hardly knows which is which. He simply pursues his vision of excellence at whatever he does, leaving others to decide whether he is working or playing.

I’m grateful that I can often reside in that zone.
