    Thanks Donald. I know there's a mirror but didn't look for the heat resistant glass. I'll check when I get home.

    I also found and ordered a manual.

    Looks like there is nothing between the bulb and the mirror. Is this where the glass should be? What kind of glass would I need to put in there?

    Alan,

    I'm not sure you need the heat glass. I believe that Durst recommended it for lamp wattages greater than 250 or 300W, so if you don't use a very high wattage lamp, you will probaly be fine.

    I have a head that has heat rejection glass in it, but the glass was crazed, so I removed it. I haven't used the head too much, but it appears that the lack of glass hasn't had an impact on the negative at all. I'm not using the 500W lamp, though.

    I recommend you look at focal point in Florida for glass; they may have heat glass available to cut to size. I know you can get negative carrier glass from them for what seems to be a reasonable price.

    I have 2 138's that I am fixing up. One with the heat absorbing glass(hot mirror) one without. If you need the dimensions, I'd be happy to measure it for you tonight.

    My darkroom project is like all my projects. Slow.
    I think I'll pass on the glass as I only have a 300 watt bulb. My main objective is getting set up to enlarge 4x5. I'll expand from there as I'm able.

    Thanks again everyone for all your help

    Alan.

    I use a Rodagon 180mm for 5x7" negatives. I also rarely bother to change to a 135mm for 4x5". Most other types need a 210 to get good sharpness over a 5x7" negative, and those can be more difficult to find lensboards for.
