This is a early 1900 Gulbransen player piano made of Walnut that I am converting to another MIDI controlled piano using my custom made solenoid valves.

These are before pictures. This piano was donated from the original owner. Yes, I said Original! It is in remarkable condition.

             

  

 Now its time for it to be converted to a bigger and better piano that would give many more years of enjoyment. In this build I decided to install the MIDI valves first and get the piano up and running. For the Gulbransen pneumatic stack the solenoids fit right in to the tracker bar tube holes with a little modification which includes drilling out the 5/32 hole to 3/16 and grinding off the barb on the valve so it could be inserted into the hole. I use a little plastic glue when inserting the valve just for a "piece of mind". We are now offering these valves to the public. Contact us for further questions. Also can be bought in groups like where made up for the Story & Clark conversion. They operate on 12volt DC.

              Wiring Solenoids finished wiring
          Installed in piano and plays remarkably off my laptop.

   Time to disassemble and build up case for instruments.

Here I have stripped the piano, veneered sides and miscellaneous parts. Fabricated new front posts that are going to support the front Stained Glass frame.
Bottom panel. Normally I have a stained glass sliding door here that has the Roll Frame behind it but in this case the piano is going to operate solely on MIDI so I'm not installing the Roll frame.  
Here the case is basically finished. I just have to strip the fall board and top lid.

 

Next I will stain and attach a new gold leaf fall board label then spray on around 5 or 6 coats of Lacquer.

            

 

On this Piano I filled the grain to get a high gloss finish. Just look at that shine. Fall board test fitted. Will need to be removed for key installation. Sharps where sprayed with black Lacquer.

More pictures to be added shortly. Stay tuned...

Come back soon.
