Hello hobby machinists. I just (more or less) finished a project that I´ve tinkered with for well over a year now.
Limited by funds as the kids needs come first I´ve had to make do with learning on and gradually improving a rather antique lathe of unknown make and age. A pretty basic machine in a decent size with flat belt drive and change gears.
While it´s very versatile in that the set of change gears is complete enough to cut pretty much any existing thread it seems that as soon as I set it up for fine feed, I need to cut a thread and vice versa.
So I decided to build a quick change gear box that would cater to my needs of oddball threads as well as extremely fine feeds when needed.
It ended up with seven reductions in the first section and sixteen in the second giving me a range of 4-992 tpi or 5mm to 0,02mm, with a total of 33 gears I milled.
It just feels so good to finally have it finished and working I had to share.
