October 2012
 

The year is almost over. The snow is coming and I don't have enough wood for the winter. Oops wrong part of the country. The beautiful weather is coming and the only wood I need is for piano work and other projects. If you need some Poplar or Maple let me know.

We have added some links above. One is to the Contribute page. Take a look at it and see if you can get your creative juices flowing. It would be nice to hear from you. Even if you don't feel you can write something do it anyway and I will do my best to edit it for the newsletter. We can always do it anonymously too.

We have our plans in order to acquire some PTG brochures and displays. Our members will have these at their disposal to use in promoting themselves, RPT and PTG. More on this later.

Our meeting in October will be the last for the year. January will be the next meeting.

Good health to you,

Dan

 
 
Finishing Wood

We may have to put a new finish on some wood when we do piano work. Perhaps a small part for player installation, hammer rest rail, touch-up, complete refinish or damper heads.

Below is a scenario for your edification

  1. Installing new damper felt and want to spray new finish on heads
  2. Heads were previously recoated. So some light sanding and use spray can paint to cover. Might be acceptable,but,
  3. The previous refinish crinkled up from the solvent in the new paint. Oops.
  4. Should have: Soaked the damper heads for a few minutes in lacquer thinner or stripper and used Scotchbrite to scrape off previous 2nd coat then wash with clean thinner and let dry.
  5. Sand to 320 or just 320
  6. Spray with quality sanding sealer & let dry
  7. Sand of imperfections with 400 or 500 paper
  8. Spray one to two wet coats of quality lacquer overcoat. Should look great.
  9. For super finish, spray 3 coats of overcoat, sand with 1800 to 2000 to smooth & buff.....naa...too much work, only with extra money.

Lesson: It's best not to spay over an unknown previous finish without doing a test first. Sanding sealer will help the new finish bond to the previous and allow for sanding to a smoother finish.

I was servicing a Kawai upright that had trapwork noise. Upon examination I found what is shown below. As you can see, the bracket to secure the pivot pin had no security, just the bend resting in a slot which was loose. Originally this was no doubt a tight fit but they should have thought "seasonal wood movement." When the pin nut was tightened, the bracket would cant toward the top and still was not secure. I drilled two holes in the bracket and installed screws to secure it. What were they thinking.

Dampers

Oftentimes damper split wedges will not damp all three strings cleanly because the two wedges need to be slightly wider; cutting the slot deeper may improve damping, but at the cost of wedges that are going too far below the strings, which can cause noise on the way out and necessitate trimming the wedges. In many situations, Iíve found that adding a bit of thin white cotton string can dramatically improve damping. This technique can avoid a lot of frustration, and ultimately be well worth the extra time.

I usually use the slightest suggestion of a coating of hide glue to the string, although I wonder if it's even necessary. When installing Hamburg Steinway felts (made by Renner) shown here, this is something that almost always has to be done, as a matter of course. The wedges go instantly from noisy to absolutely clean. Steinway should probably be using Yamaha felts, or some other with a pointier profile! But of course you can run into this problem (as I'm sure you have) on all kinds of instruments.
