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
