BV20BL lathe change gears

[ChrisBoon]

Good Day
I misplaced my BV20BL lathe change gear chart. I downloaded some from the internet but they are all for the 4mm pitch feed screw.
I need a chart for the 3mm pitch feed screw. I can sort out the gear placements, but it will take forever. It took me about 3 hours to calculate how to cut a 1.75 pitch thread and still have to test if OK.
Is anyone able to assist?
Thank You
Chris
