part 1


btw just from a machineing aspect it will be very difficut to make that alum ring gear even if you have a cnc mill at your disposal....check McMaster and granger for similar items...also if i am understanding this assembly you are just looking for a fine focus knob. if that is the case duplicating this exactly is not nessicery. you can make modifications to the design as long as it does the same job...for example small parts makes a nice small 90deg gear box that is like an inch long and really light so transfering the power from 1 motion to another might be easyer with something like that instead of building one from scratch
