Hi Steve,Steamer, (Dave Piper) made a spreadsheet - attached and I did one from Machinerys Handbook - attached.I have never cut a skewed bevel gear but it did manage to produce a reasonable CAD drawing of the setAnyway HTHRegardsBob

Hey Steve ,When you get the chance fill ms in on what I missed...Dave

Spreadsheet says offset is .4153 your text says .4513 is that just a typo in your post or the figure you are using?Also not sure where your "moving half the pitch" comes from?

Hi Steve,Just had a closer look at your jpg and if cut 1 is the upper and cut 2 is the lower then my 1st thought is your indexing in the wrong direction. Why, well again if my assumptions are correct then cut 2 would be on the other side of cut 1 and the tooth would be narrower on the inner as it should be rather than wider as drawn.HTHRegardsBob

OK. The last three steps are pretty trivial, but I've completed the spreadsheet to include them.I've renamed the spreadsheetSkew Bevel Gear calculations DP 06012016-A.xlsIt is attached below. Enjoy.Dave
