    Just in case anyone else out there is thinking about this and needs a bit of a push. They're not too hard to make, and if my first one (shown here) turned out good enough to use, the next one should not only work, but should be cosmetically decent as well.

    Okay, so I'm *really* lazy -- I have two that came with a lot of darkroom supplies that I really bought for the 620 spools...

    Who said I wasn't using them? The adjustable one (with leaves like a printing easel) will take 5x7 if I remove the leaves, otherwise up to 4x5, and I've used it several times for cyanotypes. The other is postcard format, and I'm sure I'll find a use for it eventually.

    Neither one is big enough to interest the LF junkies...

    Thank you Dan,

    I wish I could remember who passed along this next tip, so I could give credit, but....I can't remember :sad: Anyway, the glass that I used was simply "float glass", a sort of greenish tinged ordinary 3mm thick "window glass". Some one wiser than I am pointed out that this acts as a filter and restricts the amount of blue light that can pass, thus affecting the resulting print. I am in the process of tracking down "affordable" ('cause I'm a cheapskate) "crystal" glass, which is described to me by a glass dealer as "untinted" or "optically clear". Now the optically clear part, I'll take with a grain of salt, but....at least it wouldn't have the green tint.
    I hope this tid-bit helps someone.

    cheers eh?

    I'm even worse - I bought one. 8x10". Then I "accidentally" picked up five more - in all sizes from 6.5x9 to 13x18cm. some are really old, without glass, and obviously intended for glass plates. Others seem unused, or at least seemed unused when I got them.

    And 90% of the time I use the one 8x10", and the rest is the 9x12cm...

    Look for PPG Starphire glass. This stuff's as clear as glass gets, and can be ordered by most window glass suppliers.

    Very nicely made Tracy - looks like very carefull mitreing and finishing. While mine do work well, they are quite "butch" in construction due to a "need for speed" while constructing. I can think of several improvements that I will make in my next one, including one that I see in yours. In mine, the depth of the glass from the top of the frame is too deep, making it hard to easily do accurate test strips. On my next one the supporting material will be much thinner as is yours. I think that hardwood is the way to go also for the next one.

    As a matter of fact, I have wondered just how clear glass really is. If anyone knows of a good on-line distributor for quality glass, I'd love to know. My local dealers are kinda difficult.

    Schott has a web site, I believe -- they came up a while back (somewhere) in a discussion of making your own glass plates; they can apparently supply high quality glass in the 1 mm thickness needed, precut to size, for quite a reasonable cost per piece. Among other things, they list a "crystal clear" glass as suitable for optical windows, but sell the same material in a "float glass" form made the same way as window glass.
