offset taper spacing

[paradoxjim]

I compared the results from the Excel spreadsheet against a simple program that I've used for years called "Wrapped Right." Wrapped Right is a DOS based program that I bought many years ago from Clemens that has served me well over the years. The results were comparable between Wrapped Right and the spreadsheet. As someone noted, it really comes down to how accurate you can be in measuring those marks out on the blank. Tenths of a millimeter get difficul for these old eyes!

Yep , sometimes the dots you make to mark the spots are bigger than the difference ebtween the spot lenghs if its a gradual taper.

In reality , the whole thing should not be done in units of inches or mm. it should all be done in thread diameters since being able to get the right number of threads in to fill the patterns at both ends is why you do it.
