involute gear cutter for 9x20 lathe?

Hi Cap, I think one of us is missing something with this (could be me).
The data you have already states the DP (Diametrical pitch) or module is 1.
The data I have used for gear cutting is based on these pages

A full set of 8 cutters can be found

A bit expensive for a one of job, I have a spreadsheet for making your own cutters or a fly cutter or maybe you are hobbing them.

Hi, nice & thanks for the details, if could share the spreadsheet may be it would help me to make my cutters.
