Thursday at the OB‏

Jack and I were at the OB today.

Jack re-installed the bottom on the OD chest. I had replaced 4 pouches that were torn. This allowed us to get the entire OD working and we tuned it. I have ordered a complete set of valve faces and discs and we will re-leather and upgrade this chest later.

We operated all of the 8 foot octave of the RM trumpet looking for the magnet that we thought might be staying on with residual magnetism. After a 10 minute test we found the D pipe was inoperative, looks like the magnet has finally given up, so when we have time we will replace it. To do this we have to remove the 8 foot OD offset chest that is in front of it, then remove the trumpet offset. About a 2 hour job. Not a maintainer friendly design.

We have more keyboard problem, neither of the lower 2 keyboard works comletely, there are sticking keys and dead notes. We need to do something about solving this problem other than constantly adjusting them. Dave, how do we do this??

I put the last of the reeds into the Style D trumpet, we got the wind on, pipes were very weak kneed if they played at all. Tests with the water manometer showed only about 6 inches of wind, should be 10. This is one of the two regulators that Gilles Bruyere donated several years ago, made by rOY Parish for Gille's organ that never was finihed. We will replace it with one of the spares in the container that were built for the small Morton in storage, and I can rebuild it later. The problem is the fold boards are too narrow so it cannot rise up to the 6-3/8 overall height.

I showed Jack how to replace the leather nuts on the chryso. We regulated one valve seat on a sticking hammer pouch. After a trip to the foundry we stopped at the containers and dropped off the surplus pipe fittings from the windlines. We alo put out mouse poison in the FotoPlayer building. More next week.
