Hello! I was just given my families Model D, and I am trying to make sure all the parts are there so I can reassemble it. I think everything is there, but I have one part that is broken. I can't figure out where it goes, or what it is. It's about 1/2" in diameter, stepped in the middle, and since it's broken, I don't know how long. The parts drawings aren't clear enough to ID it. Any help would be appreciated! Note: I just went back through some older posts, and saw a mandrel bearing replacement. Is that what I am looking at?   |

It might be of some help if you pieced the broken parts together, the better to see what it looked like originally.
Are they plain cast iron, or are they painted? Are there any screw holes on the pieces? Any empty screw holes on the rest of the mechanism?
Some detailed pictures of the Standard itself might help to identify whether this piece belongs to it or not, or whether it might be the remains of some accessory part.
BTW: is it a model B or D? I have a model B, and have not been able to identify any part matching the photo.

Thanks for the catch, it is a Model D, not B. I have tried piecing it together, and I think there is a bit of it missing. I'm pretty sure that it is the remains of the mandrel bearing, since there is not one in the machine. It looks like cast iron, or 'pot metal', hard to say.
I have bags of parts and all the rest appear to be there. My uncle disassembled it and never put it back together, so it's been a bit of a guessing game.
Also, what holds the cylinder to the mandrel shaft? Is it a pressed fit?

For a good set of visual and technical references, the "Spotter's Guide to the Edison Standard" at antiquephono.org is a good starting point.
I'm not entirely sure, but I believe the mandrel was press fitted onto the shaft.

Thanks for the info!
I emailed a repair shop to ask about parts, and he confirmed that it is pressed on the shaft. I'll have to make a wood drift to re-fit it, so I don't damage it.

On Edison machines, they had a nasty pot metal bearing in the middle of the mandrel shaft. There are new bronze bearings made that are much better. The oiler on top also holds the new bearing in place, using the hole drilled in bearing for oil.
Make sure you have all the old pot metal bearing removed from the machine, as new bearing won't go in unless old bearing is completely removed.

To the Original Poster, Please post some more pictures of your phonograph so we can see exactly what it is. If we can't see it, We can't help you!, so Please post some pics if at all possible. You put "Standard" in your Original title, so I guess that we can "assume" that its an Edison Standard Model "D" Phonograph.
