I am interested in cutting bronze worm gears for my antique Porter Cable sanders. I have researched some and heard that the Barber Colman #3 gear hobbing machine will do this.The gears I want to cut are 2" in dia and 5/8 thick with 21 teeth.I think the worm has a 4 start thread but not real sure. I need help in choosing a machine and the best place to have hobbs made. Also how do you figure out the dim. of the gears?I am new to this and not a machinit by trade but very interested in making these gears.Please help me out. Thanks agian,Cory
