Any advice on the thickness of foam to use when replacing the seals on an Olympus 35 ECR |

I use the thin seal strips from Jon Goodman's kits; i put them in the body grooves as usual and I also glued them to the door, as was done originally:

The door hinge seal was I believe 2mm foam -- not the sponge kind, the flat kind. |

Recently, I've read some discussion about yarn, instead of foam. The older cameras from the 50 and early 60s used cotton yarn that seems to last 50 years or more. The Petri I'm working on had yard on the upper and lower door seals and felt on the ends. That's how I'm going back, but I'm also going to try it on cameras that had foam originally.
My issue is how to apply the glue. I'm thinking a hypodermic needle on a disposable syringe would be ideal, but Walgreen's said I need a prescription - a rather embarassing moment. But, nothing worse than glue all over a delicate project. |

Krafty,
The type of needle/syringe that pharmacies sell wouldn't be very good for that use - they would clog easily, and depending on the adhesive, you may have trouble with it gluing the barrel/plunger, too. They do have syringes for hobbyists with blunt end needles that probably work better. I've never needed them, though. Squeeze bottles with plastic hobby tips have always been good enough for me. |

If you've ever refilled your printer cartridges with ink, you'll probably have extra syringes that would be perfect for this application. |

I just used the tip of a toothpick to apply tiny bits of contact cement along the door. You don't need a continuous bead; use just enough to hold the seal in place. That's the way mine was glued originally, as I saw when I removed the old seals.
Yarn would work, but Jon's seals won't break down as the originals did and they're easier to work with. |

I've always worried tht yarn would slowly erode, constantly filling the camera with little fibers. Maybe braided nylon fish line would be more durable, it works fine for replacement on old leather hiking boots. |

How about a fine drinking straw with finger on end? You can control the amount you pick up and dispense pipette style. You probably have one hanging around the kitchen already! |
