Not sure if this has been done already but my Dad and I came up with a handy spreadsheet for calculating the maximum diameter of the tube fins with only the body tube diameter and the number of fins. Please note that this was generated in Open Office spreadsheet and converted to MS Excel so it may not look good.

Please let me know what you think and I will post a scan of the drawing and calcs we used to come up with this formula.
