I want to machine a spiral bevel gear on a manual universal milling machine using a involuter gear cutter. I also have a differential indexing setup for this job. But the difficulty I am facing is that how to calculate lead for this gear so that I can link up indexing head with feed . All I could find online with some research was that mean bevel angle is 35~40 degree. I would appreciate some links to reliable sources for more research
