As I start to work on the focusing rack for my medium format view camera build, I realize I need to know a bit more about my options on gears/racks available. So based upon feedback here, I went to the Small Parts website and am looking at either 32 pitch or 48 pitch spur gears and respective racks in brass. My choice right now is the 48 pitch with either 12 or 15 teeth as this will give me a smaller overall height requirement, and also as this is not going to be a bohemoth sized camera, should suffice. What I am asking for is whether this is adequate. What are others using for their view camera builds and why?
