I found a very nice Yashica Electro 35 GSN recently, on which the only thing wrong appears to be a broken rangefinder window. I know these cameras come up in the Swap Zone fairly often. Does anyone have one they are parting out now? If so, do you have a rangefinder window you'd be willing to let go? I need one with the diamond-shaped clear spot in the etched area.
I thought I'd ask before I try to make my own with picture framing glass and glass etching acid. Has anyone done that? Any tricks to it? |

I can't help you with parts, but a large glass microscope slide may be suitable and using 'invisible' cellotape on the inside surface to achieve the frosted effect. I have used glass etching acid ie. hydrofluoric acid at work, it is a substance to be treated with a great deal of respect! Also it is not the sort of material you can buy over the counter. Your local mirror specialist may help, the secret is to mask off the non-etch areas wth paraffin wax. |

I have created my own windows using glass from an old picture frame (it is thin). Glass etching past is available from craft suppliers. I have found that a good masking material is vinyl adhesive sheets (the kind used to line cupboard shelves). |

Thanks for your suggestions. Your thoughts on masking the glass are helpful. I considered using the cellotape for the "etched" part, maybe I should consider that again.
I understand the hazards of working with hydroflouric acid, but the main problem may be finding the acid. My daughter works for one of the major crafts chains, and she says they no longer sell it. It seems that "frosting" comes in spray cans nowadays, and most crafters who want the etched look use that.
I wonder if plastic electrical tape would work as well as shelf liner for masking. If I find the acid and attempt to etch the glass myself, I'll test a piece with the electrical tape first. |

P.S. I should have done some research before writing. Hobby Lobby has a glass etching starter kit that includes masking material and paste etching medium. There are also a number of on-line sources for etching materials. |
