A Python Helper Program
In my approach to the problem each part needs to be positioned ( so far in the z axis ) so that all the parts come together correctly. I started to do this by making a sketch of a side view of the gearbox ( will add here later ). Then I began a spreadsheet of the z positions. I do not really like spreadsheets because I find them very error prone and compared to programming a bit tedious. So I wrote a Python program. Initially I just set up a large number of variables and did the math. This was using Python as pretty much a general purpose calculator. Then I began to see a pattern in the calculations.
