Plastic Keytop Replacement

If you are ever interested in having your old piano keytops replaced, I would be more than happy to give you an estimate just contact me through my website.

Below: This was a picture of the piano before any work was done on it.

Below: This is where I was removing the keys from the piano.

Below: This picture shows all of the keys removed, I removed the keytops from each key and prepared the wood for application of the new plastic keytops.

Below: I started replacing the keys back into the piano with the new plastic keytops. I hand file all of my new plastic keytops for precision fitting.

Below: This picture shows the completed keytop replacement with the new plastic keytops.

Below: These pictures show the completed piano restored with a new paint job, also added 4 appliqu├ęs to enhance giving the piano a new character.

Hammond M3 Organ Restoration

I normally focus specifically on pianos but recently I embarked on a restoration of a Hammond M3 organ. I was with my wife down in Florida we were purchasing a piano from an old church which she is presently restoring, and while there I noticed tucked away in a hallway this Hammond M3 Console Organ. I couldn't help but ask if the people selling the piano were interested in selling the Hammond, the sellers accepted my offer and I now own this Hammond M3. I didn't even test the organ to see if it worked I just knew if it didn't I'd be able to fix it. I've always wanted a Hammond and this M3 was a popular console model of the 50's and 60's, the church we purchased it from supposedly used it for years. My goal was to restore it back to its original beauty and sound, so this blog is dedicated to the work done on this organ once we brought it to "the shop" for the repairs. My Dad helped with the wood refinishing part of the project, he is an amazing wood worker and craftsman, so as you see throughout credit is given to him with regards to the wood refinishing. I'll share below pictures and explain what each picture represents in the process of the restoration:

Below Picture: This picture was taken when we brought the organ in the shop, as you can see the finish looks really rough, the organ was dirty and in a non-working condition.

Below two pictures: I started with removing the upper and lower manuals on the M3 including removal of each key from the manual. This was to provide easy cleaning of the keys and the keybed of each manual. As well as prepare the organ for the wood refinishing.

Below: The plastic part of each keytop was cleaned with a rag and a mild degreaser. This removed any dirt and residue from years and years of use and brought the keys back to a clean almost new look and feeling when played.
Below: After each keytop was cleaned it was placed in a box in order for placing back on the manual keybed down the road when we got to that part of the project.
Below: Now with all of the keys removed, I carefully removed the Hammond tone generator, and both manuals through the back of the organ. I placed them on to barrels at the exact height they are in the organ to make sure any wires were carefully guarded I included a towel over the tone generator to protect it as well. This provided easy access to all of the wood for the refinishing. The above pictures shows a good example of the finish before it was stripped down.
Below: Is the before picture of the Drawbars which control the sounds, the whole unit was taken apart and fully cleaned. I used a mild cleaner to remove the residue, and contact cleaner. I also used an pink eraser to clean the contacts gently. After they were cleaned they were placed in the silver pan below until the unit was reassembled.
Below: The Amp... there's nothing like the sound of a tube amp, my hopes were to have this thing sounding like it originally did and that I accomplished.
Below top picture: The organ didn't work when we brought it into the shop, so I started by looking for the obvious and the ceramic resistor (Below top picture) was most obvious because it was burned up. So I ordered another ceramic resistor just like based off of the schematic, and soldered it in the amp and got sound out of the organ. However, after a little bit of time the Multi-Section Capacitor (below bottom picture) would get really hot so I knew those had to be replaced. Also after it got hot the sound would fade away. There is one that is silver and one that was paper covered which is the Power Supply capacitor, I replaced it as well (you will see the black paper covered capacitor in next series of pictures)
Below 5 pictures: As you can see in the first two pictures below both original capacitors have fulfilled their life "capacity" in doing what they were supposed to do, so I replaced both. I ordered replacements in a kit from a Hammond organ supplier online. The 5th picture on the bottom is the replacement kit I ordered, comes with: 120uF 50 Volt Electrolytic (didn't use this); Power Supply 50/50 @ 500V Capacitor (which is the Black one replacing the original black paper capacitor); Clamp For 50/50 @500 V Capacitor (the original had its own mount the replacement comes with a clamp); finally Amplifier Power Supply Multi-Section Capacitor (Sliver capacitor, this feeds multiple currents throughout the Amp) I just followed the schematics and soldered wires to appropriate voltage readings.
Below: the new kit replacement parts...
Below: This is looking at the bottom of the AO-29 Hammond amp, you can see the bottom of the original Multi-Section Capacitor (Sliver capacitor) before I removed it.
Below: Pictures of the amp after I repaired and placed back in the organ. Amp and wires look clean and neat also notice how brightly glowing the tubes are now... Much better than before.

Below: While working with the amp and other items, Dad was refinishing the wood back to a satin finish to look more original below pictures show his woodwork.

Below: Final pictures of the reassembled organ, fully cleaned, refinished and tone generator was also cleaned and oiled appropriately.

Below: As detailed as my Dad is, he even polished all of the screws as you can see here they are looking really nice.

Cable Baby Grand Restoration Completed

Well this is my final post on the Cable Baby Grand Restoration. I have not taken time to update this blog lately and the project was finished in May 2012. The Bass Strings are now in and the finish of the piano is also completed. The project turned out amazing and to my satisfaction, I have posted some pictures below of the finished piano.

Above: Before pic of the old bass strings.

Above: I replaced the keytops, still some minor adjustments will need made (e.g. D and E natural next to middle C) but they all work great.

I have a whole detailed album of pictures on my Facebook page so head over and check those out...

Treble Strings are all in...

This weekend all the treble strings were finished. I installed all new felts, pin bushings, pins, strings and stringing braid. Now waiting on the bass strings to arrive...

In the meantime I will be working on regulating the action and keys. From what I can tell so far, this piano is going to have a great sound and it's looking BEAUTIFUL!

Just for the record my back and feet are very sore and restringing a piano is hard work. I'm presently on the couch with a heating pad on my back.
