Create a helical involute gear on an existing shaft

[maxwxyz]

Not sure if it is possible (otherwise maybe a feature request):
I am trying to create a helical involute gear on an existing hollow shaft (see: FreeCAD forum)

Is this possible with the Gears-WB, especially with the "chamfer" or phase out of the teeth into the existing shaft? Is it also possible to create an inner stub shaft spline with Gears-WB on an existing hollow shaft?

not really. I tried to create something similar with the part-wb and gear-wb, but I guess this is not what you want:

not bad, would you share the file or tell me how you did it?
