Absolutely well. How can life be anything else when you are a photographer? (At least, never bored! There's always a new process or project to be tackled.)
Yes, the frames come without glass because the negative plate is the glass. You set it in the frame with printing paper cut to the same size and clamp on the frame back.
A couple of years ago I bought my first 4x5 contact printing frame off ebay and I've done run all my own plates and a few antique ones through it since. I just measured it. The backside opening is 103mm x 128mm. There is ~4mm lip around the front side to hold the glass in, and also mask the unexposed edges of the plate. This leaves the printed image 95mm x 120mm.
Good luck and fun with your latest projects .
