As mentioned in my previous post I guess I'll have to make some threading dials for my lathe...
it's a DeVallieré H-130 set up for metric stuff (Page Title)
I know that with a lathe set up for imperial threads / american stuff the gear's Tooth Count of the threading dial would have to be a multiple (4x) of the TPI count of the Lead screw....
I also know that for a metric lead screw to cover the whole range one needs several gears...
But how to calculate how many teeth the gears must have... ???
my lathe can cut threads with a mm pitch from 0,45mm to 4mm (so it's quite a broad range)....
I mean there must be some equivalent type of calculation I can do to figure out what gears I must cut...
thanks
