RE: strong tape of 0.15 to 0.20 mm thickness
Lee Valley tools carry a thin teflon tape (www.leevalley.com). I think that this would be ideal. Very low friction and durable. I am not sure of the thickness tho.

The reason is that I have a new "toy" camera but I like to shift the focusing distance somewhat closer than the camera's default. Moving the lens outward is out of question; I've decided to move the film back. The preferred offset is about 0.18mm. I need a tape with the following property: 1. thickness of between 0.15 and 0.20 mm 2. strong, durable material, preferrably hard 3. low friction on the surface 4. strong adhesive Duct tape has 0.15mm thickness, reasonably strong adhesive, but it is not very hard nor durable especially when there is friction against its surface. I'm looking for an adhesive tape made of hard plastic tape or even aluminium or copper. The perforated part of the 35mm film is run against this tape surface. That is, the tape is affixed on existing film guide rails and the tape surface becomes the film guide rails. Duct tape can withstand friction for a roll or two of 36exp film, but it tends to wear out during rewinding process. Currently I'm using duct tape or similar tape but I have to replace the tape frequently. If you know of adhesive tape products that meet these criteria, please let me know of the brand, product name, product web site, etc. Thanks! Ryuji
