    dp I like it,
    curious how did your gears roll against each other did they feel smooth.

      Yes it did. It fit an existing rack I had.

        I recall John Stevenson found and corrected an error in the button method Ivan wrote for making cutters. It is probably in the archives here.

            This is the correction for Ivan Laws book page 106-107. It also went "somewhere" else as a post but I don't no the location.

            This is a link to spread sheets that will make easy work of dividing on a rotary table, if that is what you use, just enter the # of divisions and hit enter, easier then using a dividing head. One is for general dividing as in spur gears, there is one for dividing to cut bevel gears using the parallel depth method (Ivan's Book) and a spreadsheet calculator to do the math for parallel depth bevel gears according to Ivan Laws book. It works as far as I can tell.

            All spreadsheets must be downloaded to your comp. pad or phone, they do not work on the site.

            Hope this helps

            The shortest distance between two points is a circle of infinite diameter.
