| p.1 #1 · Modifying Kippon-style Contax G adapter --- idea |
I was going to post this in one of the other threads, but it was different enough that maybe it should stand on its own.
My understanding of the Kippon adapter is that it has a large outer gear driving the small brass geared focusing tab (I've looked inside a Metabones, but haven't taken apart my Kippon yet). Part of the grittiness is when turning the outer ring, the pressure against the brass gear varies. Thumb or fingers close to the screw: smooth; thumb and fingers away: gritty.
What about putting in two dummy gears at 120º and 240º to make a 3-point of contact connection? I envision drilling four small indents (2 top and bottom), and putting in some sort of small brass gear (I have no idea where to get one, but haven't even looked). The gears would just spin against the outer ring for tension, and would obviously need to have the right ratio compared to the focus gear.
Does this sound plausible, or am I overlooking something basic?
