Hi,

Can anyone tell me what the pressure angle of the gears in a Boxford AUD lathe apron is? I suspect it is 14.5degrees rather than 20 degrees but I want to be sure before I splash out on some cutters.

Regards,

Alan

You should be able to see the difference in tooth shape at the root. Comparison pics are to be found on the net or in gear cutting tomes. 20 degree pressure angle teeth are wider at the root. I expect (guessing) it will be 14.5 degrees - at least for earlier models.
