Hi guys,
Once again I am lost. On my srT the cement/glue between the small prisms on the penta-prism had become completely opaque. The smaller prisms popped right off when I took the dental-pick to them. I have cleaned them and am ready to glue them back in place.
What I want to know:
What kind of glue do I need?
If I use one that requires UV light to setup/cure, will a black light work?
I need to glue one of the rings that hold the little calcium sulfide light sensors in. How should I glue it on? I don’t think the same adhesive was used because the denatured alcohol readily dissolved the cement on the prism but had little effect on the glue around the ring.
Oh and last any recommendations on what kind of paint to use the prism after it is all back together: latex, acrylic, or something else?
Thanks guys I’ll appreciate any help or suggestions,
Aaron Howard |

use acetone to make ssure you have the old cement. I use Duco cement for regluing. Get them in position and wrap (this is done with prism out of camera) arouond the asssembly to hold while cement dries. Have no particular recommendation on paint. |

You can use epoxy glue for re-glueing the sensors - but things glued together with 2-part epoxy glue hardly can be separated if necessary. You can use any other glue which is suitable for glueing metal, glass etc. |

As for the paint, I guess you're talking about the black paint on the non-reflecting surfaces? (I don't have an SRT prism handy but most prisms and lenses have some edge blacking).... I just use Testors black model enamel for that. Gloss or flat doesn't matter, since it's the glass surface that establishes the finish anyway.
Good idea re Duco cement, I haven't tried that (yet).....

rick-- i had not even stopped to think. you are right though the glass is the finish so it does not mater if it is a mat or gloss.
thanks to all
