The trick was to expose Polaroids that were in the process of developing to x-rays. Simply block the shutter of a Polaroid camera and then take a picture. This ejects a single Polaroid film with the developer paste spread between the layers of plastic. At this point the picture is being developed. If left untouched it will turn black in about 60 seconds. The film is no longer sensitive to white light, so you can work in a well lit room. Before the film has automatically developed you have a brief window of time in which the film is still sensitive to x-rays. This makes the job amazingly simple. Just setup your object to be x-ray photographed. Take a blank picture with the blind Polaroid camera. Place the film behind the object. Expose the object and film to x-rays. I found that 2 seconds of 80KV was enough to image bones in the foot.

Yes - I know, experimenting w/ X-Rays is dangerous. Be sure to read the safety and dangers articles.
