involute gear cutter for 9x20 lathe?

I am looking for the parameters for the involute gear cutter set to make all the gears for the 9x20 lathe?

I think the DP is 1 and the PA is 20 but I cannot verify those numbers? and I cannot find any cutters with those numbers?



Help....Thanks

Found this, may be of use.

Olderdan , Hi I found that one too but can't verify the DP any where else and can't find any cutters to match these numbers? Thanks Cap.

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.

Wow Thanks for the info So do you think if I order the gears from amazon they will be the right ones for making all the change gears?

Thanks olderdan.. can anyone else verify making gears with these parameters for the 9x20 lathe??

I would have thought that any import lathe would have had modular pitch not diametrical

To find what dimetrical pitch you have try this chart

the charts I posted were screen shots from the Martian Sprocket & gear catalog called the big catalog it can be found here free download but be warned it is 61,387 kb
so it will take some time to download if you have a slow connection mine took about a minute but there are smaller target sections which can be downloaded on the same page these can be found here

I have a hard copy of the 2000 catalog and both the 3000 and the big catalogs saved on my computer very helpful for many tasks

WOW thanks Frank S ill try that download.

OK Guys Thanks......Got It.....:O)

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