The tooth angle is 14.5deg per side, linear pitch is .448" (edited) averaged from 9 teeth using .25" endmills in the gullets, if I remember right. All the videos and websites I've gone though the last week either have confused me to the point I missed it or hasn't taught me how to work backwards from rack to spur gear. Am I right in figuring the .488 isn't a nice, pretty round number because the circular pitch of the original mating gear made it so? Would that have started out at a .5"cp and I can work the linear backwards from that somehow, or is that just silly?
