Hi :

Sorry about that, there isnt much documentation on that subject as yet. You should make the blank to the size shown in the information for outside diameter
of that gear on the project screen. The stock display is rather loose in that its just trying to make a blank for display, Ill check why its saying differently, but your stock should be the same size as whatever is reported as the external diameter. All cuts are based on that.

Thx

thought I'd replace the HEAD with a compass I made in Rhino
just an alternative, now that it displays for me,
