Cameras like Nikon F/F2 and Yashica TLRs (635 and Yashica Mat) uses an older shutter release which have an external screw thread. They require a different shutter release cable to trigger the shutter. They are much less common and expensive. However, I found a way to make a shutter release from a bicycle tyre valve cap and standard shutter release cable. Most people will have these at home and will not cost you any money.
Step 1: Drill hole on a tyre valve cap
Step 2: Screw in shutter release cable
Step 3: You are done. This is the cable release fitted to Yashica 635
