    Course GG...

    In the course of my learning with an old Gundlach, I have found the groundglass (probably original) to be very course. I find it difficult to focus quite often because it is course enoguh to obscure a lot of the fine detail you use in focusing. I think I would like to try replacing it and see if I am happier. On the other hand, if there is anything I can do to the existing glass to make it finer, I would prefer that.

    I read somewhere that a very fine gg can be made by drying skim milk on one side of clear window glass and then varnishing over it. Has anyone done this?

    Any other recommendations that, preferably, cost very little (I'm a student...a poor one at that)?

    seconded. I love mine, and every time I switch from my 4x5 with to 5x7 without, I really notice the difference.

    That sounds wonderful and is half the price of a lot of GGs I found other places. I think I'll be getting one very soon..or very soon plus the waiting time :P

    Dick Dokas wrote an article in Photo Techniques a couple of years ago on how to make your own gg. I have re-surfaced several using his technique and have suceeded in making extremely fine grained gg's.

    More information on making ground glass is at http://www.f295.org/DIYforum/cgi-bin...1700672/s-all/. One source of thin glass is cheap picture frames.

    The guy who runs Satin Snow posted a message in another forum a month or so ago and said the current waiting time is about three months IIRC.

    Could you explain the jist of the article? It only shows me the first page or so. I know the basics of grinding glass but what I don't know is the grit to work down to to get a nice fine glass. I'm trying to avoid spending a bunch of money on a lot of different grits to try them all.
