Reset Infinity
Because we have moved the film plane by the addition of the pack film back the position where the camera focuses at infinity must be reset.
All of these roll film cameras have a stop which the lensboard locks into when opening the camera. Some have the ability to be adjusted back and forth. I found a few 95s DO have adjustable stops, but apparently not this one I'm using.
This stop is riveted in place. So to make any adjustments, remove these rivets.
Either grind from the top or unscrew the focus rails, lift it up, and drill from the bottom.
If you try to move the stop back, it gets caught on the 2 large screws that hold the focus rails down.
You will need to remove the sides to allow movement back.
There is another way to do this without cutting the stop. If you have access to another roll film model which does have an adjustable stop, you can harvest one. I took one from a model 150.
Lock the lensboard into the stop, either a cut one or an adjustable one. It should now freely move back and forth inside the rails.

Grab yourself a tripod and some ground glass within an empty film pack. If you don't have any ground glass a piece of tracing paper taped inside will work just fine, just make sure its flat and not wavy.
