Transport screw workaround for wade extruder

I had some difficulties to get the wade screw ready properly. I tried the tap-method but was not successful so I decided to try the teeth version. This "thing" will show a method to get a desired amount of teeth into the bolt and how to divide the surface of this screw into exactly same sized teeth.
