holmburgers, search Ebay for "Leo Catozzo splicer", you'll find pictures. For instance, http://cgi.ebay.com/Dr-Leo-Catozzo-M...ht_4814wt_1138 . I find no reason why it wouldn't run in a normal 35mm camera. The requirements are not so high in still photography. Motion picture is different, though, as precise registration is must and the perfs must endure the film tension and driving force.
fschifano, well, DIY film does not serve any practical purposes, which is true for most hobbies, including photography for most if not almost all of us here. That's why they are called hobbies. I find it very interesting to be able to do my own film.
