Hi,
Does anyone have gearcutting data for the changewheel gears on this lathe. Specifically the Tufnol tumbler gears 26 tooth; 2.00" dia, but what pressure angle and form is it a British or American standard. The involute cutter that I have is 14.5 pressure angle but this when offered up to the pinion there is a light gap at the flanks at the root?

Thanks for reading this post
John
