I need to renew the mirror bumper on my Yashica TL Electro X 35mm SLR. I've done a fair few of these on different cameras but the Yashica has a metal plate at the top of the lens mount, in front of the mirror bumper, which is going to make access very difficult. There's no obvious way of removing this plate or getting into the lens mount apart from a screw at the top which presumably is for the top cover. Does anyone know if this plate can be removed without too much dismantling? Thanks in advance. |

John,
I have found an easy way to do this. And it doesnīt require any dismantling at all. You only have to turn the camera upside down and secure it in that position. From here on, it will probably take longer to explain than to do it.
I used a type of adhesive backed foam, but You can use any foam and some glue. Apart from the foam, all You need is a needle bent to an "L"-shape and a steady hand.
You simply push the needle into the foam strip at the side that should face the mirror. Remove the paper covering the adhesive (or apply the glue). Then You just offer the strip up to behind the metal plate and make sure it sticks. Remove the needle. Job done. |

Thanks Lars that's understood, I'll give it a try, but I have to say that it's scraping out the old sticky foam which is going to be the trickiest bit. |

I had another idea. Prepare the new bumper with adhesive on one side, then temporarily stick it to the edge of the mirror by something which will evaporate (saliva?). Now operate the mirror lock up, and the bumper will be pushed up into the correct position and the adhesive will stick it down. Or will it? |

I tried that method first. Didnīt work very well for me. First of all; I found it difficult to operate the lock-up in a slow controllable way. Secondly; it was hard to tell where on the mirror to put the foam. It ended up either on the focusing screen or on the metal light baffle. And since the adhesive bites instantly, it was hard to remove for a retry. The above described method worked first time. |

Saliva is what Jon Goodman recommends for his seal kits. It will delay the adhesive action plenty long enough for you to get the bumper into position. Don't worry about using the mirror to push it into position; it will stay once the saliva evaporates. (Although on the X, the mirror lock-up is easily controlled.) |

Yes, I agree with Donnie - licking the adhesive side once the backing paper is removed gives you enough open time to place the bumper foam. The needle trick can also help I guess but lick the foam first. Jon Goodman has provided detailed instructions for the TL Super here:

I'm not sure how the Super differs from the Electro X but I've found that my TL Electro has the same U-shaped mirror bumper. |

I've done a few foam replacements on Electro Xs. I have to say I didn't think it was that big a deal. Invest in some quality precision tweezers for both removing the old foam and attaching the replacement. A modicum of manual dexterity is called for, but it's more tedious than challenging.

Well I sorted it,yes it is a U shape but I just replaced it with a single straight piece of foam. What an odd camera. An electronic shutter, but manual exposure setting. There are two red arrows indicating over and under exposure. Correct exposure, no arrows or indication - its a little disconcerting. I'm hoping to put a film through it tomorrow. Thanks to all for the advice and comments. |
