Seeing I made this again I thought I would pass on how I made this contraption
First I made a tube out of some black corrugated packaging that I found, I cut it just under the minimum focal length of the Canon 60mm macro lens, I then made a squire tube to fit over the round one and gave it flaps so I could tape or glue the face plate to it but found tape to be ok, the outer box can slide on the inner tube so you can get the negative to the correct focal length you want to set it too, the only thing not showing is the film holder which is just a folded piece of card to hold the film.
To take the picture I used a white screen on the monitor and adjusted the camera to get the correct exposure, hope this helps anyone interested in getting their pictures from slides.
