You mean instead of messing with the threads on the shaft itself just weld, drill and tap the threads inside the flower nut itself? That's actually a pretty damn good idea. Seems much simpler than my original plan of messing with the threads on the shaft and using a nut and then either fashioning a new flower nut or drilling an indent into the original flower nut to give room for the nut to sit.
My only concern with this of course is that hopefully they used a realistic tap/die set (either imperial or metric) at the factory and not a set with some weird Chinese system of measurement (LOL) so my new cut threads will match the threads on the shaft. Other than that I might just do both threads on the shaft and the flower nut to make sure they will mesh with no issues.
