Restoration of a Clavia-Concerto for Steven Baskin 67) Sorry about this being fuzzy. My new camera has a
very finicky shutter. You really have to hold very still. This shows the new
hammer butts after they were worked on by me. They come with these spring points
lubricated with a lubritious paint that squeeks and clicks during use. All new parts
are coming that way now but the old felt bushing method is still far better. I,
therefore, scrape that paint out and glue in old fashioned spring punchings lubricated
with Teflon powder. 69) The new hammers glued into place. 72) The original dampers levers are recieving new spring
loaded flanges and heads, new spring punchings and the felt is checked and cleaned on the
base damper lift rod areas. The replacement of the entire lever would have left us
with some problems due to unavailability of precisely matching replacement parts of that
type. The originals were in good shape. Not to mention that the price of piano
action parts for uprights have tripled since Baldwin shut down their Mexican factory and
everything went to Japan. I have had to use ingenuity to come up with finished
products that are as good as new by replacing key components while keeping good parts that
are irreplaceable or priced to death of late. 75) These are the "tongues and flanges" that go
with the whippen and sticker assemblies. These are often the first parts to go when
these parts wear out. In order to perfect these parts, I installed all new tongues
and flanges and refelted the undersides of the stickers (the square rods that transfer the
key motion to the hammer.) 78) I originally planned to replace the whippens but the
installation of a Pianomation system brought a very good idea to mind. By using
softer voicing on the hammers and placing the Pianomation so that it actuated the whippens
exactly the same way the old player piano mechanism used to, I was able to borrow the
upwards pressure of the keys to add volume and control to the Pianomation that otherwise
is lost when installing the mechanism under the keybed. In addition, I discovered
after getting the keybed out and working with it that it was not as string as one could
hope. Cutting slots in it to accommodate the Pianomation was ill advised. So I
came up with a unique solution. Because the original whippens had always been set up
to interface with a player piano, I could use their shape to accommodate the Pianomation.
This meant that I had to glue and screw Hornbeam arms to the flat parts of the
whippens and then cover those with hard felt. New whippens do not have any means in
the way they are shaped to make this possible. This design will improve repetition,
loud and soft play. 81) All the loose boards for this piano and one other of a
similar color all refinishes and ready to be reinstalled. 84) Another angle of the solenoid rail ready for the poppets
or actuators that move the action. 87) The original restoration I did to the keys was
beautiful. Thankfully, this project had to wait a while and the piano was with me a
good long while. The glue I was provided with caused the keytops to turn brown over
a period of about eight months. If I had been a production shop, this ugly problem
would have developed in the customer's home. As it stood, I was able to recover the
keys using a more tried and true glue and produced a lovely effect again which, this time,
will not let us down. 90) The top board had to be glued back onto
the piano for which I didn't get a photo. Here, the action/Pianomation assembly is
in the piano ready to be regulated. All the strings have been chipped up to pitch
and set into the plate pins, tuning pins and bridges with the appropriate tools and
techniques. 93) This is my pneumatic device for pounding in actions.
It has a soft platen that sits on the keys. This device delivers a heavy blow
to every key in the piano about once per second. I leave it on for about 20 hours
which is well over the equivelant of playing the piano for fourty hours. 96) The assembly of the piano partially complete. © Copyright 2010 {David Rodgers' Piano Rebuilding}. All Rights Reserved. |
