David,
Here is my take on your question. You might want to consider my opinion. On the other hand, you might elect to ignore it. Your choice; you will have a lot of company if you choose the latter!
First ask yourself why there is a cheek piece. It is there to facilitate aligning your eye with the sights. On a well-fitted rifle-gun you can close your eyes, throw the rifle up and when you open your eyes the sights are aligned. Why make a rifle that doesn't fit the shooter, presumably you, just because you want it to look like a rifle that didn't fit some other shooter 150 years ago?
When I build a rifle I leave the cheek piece quite proud of the stock until the sights are installed. Then I go through the process of closing eyes, throwing up the rifle and then opening my eyes and noting where the rear sight is relative to the front BEFORE I make the ingrained mistake of moving my head around to achieve alignment. I then adjust the shape and size of the cheek piece to bring my eye into alignment. The amount of adjustment is also controlled by the length of pull, drop at comb, drop at heel and cast-off of the stock. Since all of these factor into achieving optimum sight alignment, a fixed measurement of height above stock surface is of limited value without measurements for all the other parameters too. Also keep in mind that most of us have been raised on factory built guns and have become habituated to adjusting our cheek-weld on the stock to align the sights. It is always a compromise. Build the rifle for the shooter, to facilitate hitting. That is the essence of the difference between a factory-built and a hand-made gun.
That's my story and I'm sticking with it.
Best Regards,
John Cholin
