TToC Test

I collect and use older cameras so I have several different types, Polaroid, Kodak TLR's, Voigtlander folders...so on and so forth. I've tried and rather enjoyed doing some TTV (through the viewfinder) but I want to take it a step farther and shoot through the lens of these older cameras. I tried this last night but couldn't get the results that I wanted.
Here is what I did. I took an old polaroid colorpack camera, I chose this one for two reasons, one I can completely remove the back without damaging anything and two because the shutter will stay open (if youhold the button just right) I have an m42 to EOS adapter that allows me to shoot without a lens on the body. With the adapter attached I placed and aligned the Polaroid camera lens to the sensor of the EOS and tried to focus the Polaroid, I couldn't get anything to focus. Next I took an older lens that I have, removed the rear element and "bracket" attached that tot he m42 adapter and then placed the Polaroid in front of that. The results where nice, but not what I wanted. What I ended up with was a fixed focus macro lens. I was hoping to have a aged fix focal length lens.
So the questions are, what did I do wrong? is it possible to shoot through an old camera and get the results that I want? What else do I need to do?
I can't understand why it doesn't work. I know that the digital sensor is further back from the film plane, but that shouldn't make it a fixed focus lens, that should just make it a "macro" lens? Right?
