16x20 Contact Printing Frame
I only made one of these. I guess you could call it the prototype. Some one asked just before Christmas (2010) if I would be building any larger sized frames. After stocking my shelves with some nice 9x12s and 11x14s
which, by the way, are not selling very fast, I decided to go ahead and build a larger (and less expensive) frame.
The brass springs and channels got real costly and almost impossible to find, and as much as some folks like the shiny stuff, I'm going out on a limb and eliminating those very expensive parts. The springs on this frame are made of wood. I didn't use brass spring tip channels. I also went with a plain plywood back design. The hardwood edges are nice, but don't add a lot to the frames (except time to build).
Believe it or not, oak makes a great spring. I compared the force from the brass springs to that of some oak pieces I made up, and clearly, oak is the winner.
I used 3/4" ply for the back on this one, but I think it's overkill. I'll use 1/2" on any other 16x20s.
Here are a couple of other shots of the finished 16x20 inch frame. I hope you like it.
I'll call the new reduced-brass design "Utility Frames" even though I still use corner finger joints, wide hinges, and nicely finished cherry.
