Everyone has a different method.. The best I've found is on the Airfield models site.

I like his method of drilling both the surface and TE together on a press for perfect alignment then cutting the bevel after the holes are done.
I use a router table for the bevel.. small Table saw or hand plane also works.

As for fitting the taper on the hinge.. I use a small square jewelers file to open up the hinge pocket. make for a nice fit with the square shank on the hinge.

This is the hinge line on my Stick using the Airfield methods
