Hello Metalworkers,
I would like to cut some threads on my lathe and while I can follow the charts provided to cut standard metric thread pitches I would like to cut ones that are not listed, specifically a 3.1416mm pitch (i.e. Mod 1), unfortunately I have no clue at all on how to determine what I need to set gears to. I would like to learn how to fill in the gaps in the charts and learn how to determine what numbers of teeth etc I need so I can cut gears myself (which I suspect I will need to for a Mod 1 pitch).
Mostly I do not understand what my A,B,C and I, II, III knobs do, my readings on gear ratio's etc have not help me with this.
I have posted pics of my lathe chart and gears knobs if that will help. The 30/100 gears are also removable from the banjo so I don't know why these seem to be shown as fixed in the diagrams
Any help/explanations would be appreciated
Eric
PS are there and clubs or gatherings in the north east suburbs of Melbourne to attend? say around Heidelberg/Bundoora?
