Needing to make a large spur gear. 12 dp 14-1/2 degree. 8.750 to 9" outside diameter. My machinery's handbook goes up to 8.50 but want to make one a tad larger. My math shows a 9" gear with 106 teeth, using either a #53 plate with a 20/53 advance or the 43 plate with a 16/43 advance. Am I anywhere close?
Thanks, Jim
