This is helpful information. Thanks for all your great videos.

So, how accurate are the circular approximations to involutes used by people utilising the "button" method of making gear cutters, Joko ?

I have not used or investigated the button method. I know that mchinists get them to work. There is pretty decent design information here:

Good luck
