Like the pdf how complex it can be .
The way I found is paper between the gears on setup. It fast and easy.?
Most gears like a gap of 0.005" [0.12mm] .
You adjust the paper layers till gears run quite.?
Today I can feel the gap need.
The 0.005" [0.12mm]?gap is only for most change gears in machine shop. Larger gears needs a greater gap and watch gears need a lot less. But here we do not care we are working with mini lathes.?
