Easier & more accurate to use pythagorean mathematics champ..
we have a right angle triangle, we know the angle, 2 degrees, and we know the length of the adjacent side (length of plank behind neck joint to be trimmed call this x)
so tan 2 * x = the length of the opposite side (opposite to the 2 degree angle) measure this far down the end of the plank from the face, connect the dots, use the protractor to check your work.. ;)
Si. You can also use a band saw (which I would suggest anyway) to do this. The recess for the lid and the extra (I call the sound recess) are best done on a band saw.
NOTE: the pic above might have the angle exagerated. It is a 2 degree BUT the scale/length might be off. I did this quickly and with little measurement. DO PLEASE use a ruler and protractor.
Ok, so this doesn't look as good as I thought but it should give you the idea. You could extend the reinforcement to go under the tail to add more material.

So pleased I spent all of 1987 learning it
So pleasees
Sin Cos and Tan are far too murky in my past.
