Hello folks I just received 2 sets of new gaskets for my Model C reproducer project. Or ordered a spare set, just in case. So, they all arrived in 1 envelope. There are 2 black thicker ones and 2 red thinner ones. I am now assuming that a gasket set contains one black thicker one and 1 red thinner one? If so, where does the thicker one go and where does the thinner one go?  Best regards Bernt |

In mine I have 3 (1 metal and 2 rubber)
there's a gasket on each side of the diaphragm and the metal gasket is between the round nut holding it all up and the rubber gasket.
could you post pictures?

The metal piece is not really a 'gasket', but a washer, meant to keep the compression ring from deforming the gaskets. Incidentally, there were originally also thin paper washers in between the gaskets and the diaphragm, meant to keep the copper and rubber from reacting chemically. I don't know whether the modern gaskets need these, though.... Unfortunately, I don't know which gasket goes where, either....  BillS |

I am not sure it matters whether you use the thin red or thicker black ones. I have used both successfully. I prefer the black ones, as sometijmes the thread at the bottom of the reproducer head into which the diaphragm compression ring screws can be a bit poor. By the way keep oil away from these gaskets as they deform wildly if you don't!
Good luck

Hi all,
I am a bit suprised as I thought that this would be really common knowledge.
Anyway, according to APSCO, the reproducer should be assembled as fiollows:
1 Housing
2 Thicker (black) gasket
3 Diaphragm
4 Thinner (red) gasket
5 Metal shim
6 Nut
No paper shims required.
Maybe this info will help someone else out there.
Best regards
Bernt

I am a bit suprised as I thought that this would be really common knowledge. Bernt, First time for me and I've rebuilt more Edison Reproducers than I can count in 45 + yrs of collecting. All the gaskets that I have purchased were all of the same thickness (.032 approx) and color. I can't say if this is an APSCO feature only, but I suspect it is. BillF |

Hi Bill
This is my first ever Edison reproducer so I don't know.
The bkack gasket is .8mm thick ~ 31mils and the red one is .42mm ~ 16 mils. They seemed to fit in pretty well.
One problem is that I see a bit of swarf on the (new) stylus when I play a record. Not much but it is there. Is that normal?
BTW: I tried to make my own gaskets from a rubber glove but I wasn't able to cut them properly. The rubber kept stretching and it looked terrible in the end. To make proper gaskets, one would need the correct opunch and die - or cast them.
Regards
Bernt

Bernt,
You should not be seeing any shavings with the new stylus. Something is either not adjusted properly with the stylus' bar's lateral movement or the weight's side to side movement.
When you lift the Reproducer off the cylinder with the lift mechanism , does it disengage from the surface entirely?
I wouldn't play any more cylinders until the problem can be rectified.
BTW, where did you get the new stylus?

Hi Bill What should I do about that? I now have a second Model C reproducer that I bought, in case I can't fix the original one and it produces similar tiny curls of wax. Yes, it lifts off completely. The weight is sort of floating when the stylus is on the cylinder and it can also move lateral a little to centre in the groove. Anything else I can check or take a picture of for you? Maybe it is just too warm here for these cylinders? We have 28 Celsius ~ 82degF Regards Bernt |

The only other thing I can think of is that the stylus bar body is some how coming in contact with the surface of the record. Ie; the stylus is not in full contact with the record surface. I have seen this with 4M stylus bars where the sapphire had moved or had broken off and the bar was gouging the record. Ha! It's currently 41F here with snow due tonight.  |

Bernt,
How are you making out with the swarf?
