I have purchased a couple gears with the correct number of teeth from Motion industries. They will need modification but should be easily doable. I should have them by next week.
I just looked up Motion Industries and found "rough stock" gears with the right specs. I will keep them in mind and also keep searching. I plan to call Clausing once again next week.
Would it be possible for you to let me know how things turn out once you receive the new gears next week?
Thanks for your help.
