Need Help With My First Edison Cylinder Machine
Posted: Sun Feb 08, 2009 2:48 am
I was just given an Edison Standard Model A cylinder machine. I stumbled on this board in the process of finding out what I have. It's going to need a lot of work as it has several problems and missing parts. Here's what I have figured out so far.
It looks like an early model A, serial number S47112.
The reproducer look like the model B with a tail as shown on page 80 of The Complete Talking Machine, and is missing the stylus bar and linkage. The copper diaphragm looks to be good but the rubber gaskets are dried up. My reproducer is held in by 2 half moon shaped tabs and I have a thumbscrew that rotates the reproducer.
The main spring is broken where it attaches to the center shaft, and the motor drive gear has a broken tooth and a bent tooth next to it. Also the first gear that the motor drives is missing a tooth. I'm guessing that when the spring broke, the recoil caused the gear damage.
The motor chassis is mounted to the bedplate with 3 screws. The hole in the motor chassis is much larger than the diameter of the screw. I have a lot of slop and think I'm missing some kind of rubber grommet or isolation mount. I've seen the springs in some of the parts blow-ups for the Model B Standards, But I don't think I have enough length on the screw to accommodate 2 springs. I would welcome close up picture of the proper setup.
I also got a pretty nice morning glory horn with painted flowers in the inside. The paint looks original but looks very thin, and I have a few places the you can see through to the metal. It's also very dirty and I'm not sure what to use to clean it. I don't want to do something stupid that will harm the finish.
I could also use some sources for the parts I need and agood source for a replcement decal for the front of the cabinet.
Thanks in advance,
