795 forum posts 34 photos | Hallo all. I am building a model submarine and wish to fit two viewing domes into 35mm diameter apertures. I believe that high dome watch glasses would be suitable if siliconed in, but having no experience with watch glasses I have to ask the apparently stupid question......does a 35mm watch glass fit a 35mm aperture? I ask this because the watch glasses also seem to have a flange which is OK provided that it is the glass and not the flange which gives the 35 mm measurement. I have tried contacting suppliers direct but they are so cagey and refuse to give advice on measurement. Why? So I have asked the question at the fount of common sense! Mick |

795 forum posts 34 photos | Trevor......no, but I will get onto them now. Ian.......they won't give any fitting advice. I have taken another look at website photos and I now have a feeling that watch glasses do not have a flange. Can anyone confirm? Mick |

1723 forum posts | You didn't ask for fitting advise Mick, usually fitted using a cup and dome compression tool, thought you only needed diameter sizes. Silicon glue doesn't care whether a flange or not. Regards Ian. |

795 forum posts 34 photos | Thanks for the help gents. My problem was really in misinterpreting the online images which made the glasses look as if they were flanged. Now that I know otherwise, no problem, just order 1mm larger than the aperture. Mick |
