Making a Ground Glass
The sound of glass breaking whilst your back is turned on your camera is never a good feeling. On a trip to Petrified Forest National Park that is exactly what I heard as I was trying to pack up my gear from an image I had just taken. When I turned around my camera was tipped over with several pieces of what was my ground glass lying next to it. I couldn't believe that I had just broken my ground glass on day 3 of a 5 day trip! Luckily, I still had a chunk of intact ground glass that I could move around to check if my image was in focus.
When I arrived home from my trip, I thought that I could easily find a replacement for my Graflex Graflok back at a reasonable price. Wow, was I wrong on that! I discovered that replacing a ground glass was going to run several hundred dollars, which was outside of my budget. As I investigated further, I came to realize that my view camera's focusing screen was nothing more than a piece of glass that was ground with an extremely fine grit grinding powder.
As I discovered making my own replacement ground glass was extremely easy and very inexpensive. So I purchased some carborundum powder, also know as silcon carbide, had my local improvement store cut me an exact fit piece of glass, and I ground my way to a new ground glass.
