Excellent progress - just don't try to hurry the last stages (I am usually tempted but try to resist)
As for the cheekpiece, I try to get it to "flow" smoothly from the top of the pistol grip and then keep the base of the cheekpiece more or less
View attachment 205335View attachment 205336 parallel to the underside of the butt - the angle of the base of the pistol grip is another point which affects the whole appearance of the rifle - in my case I find that for me, the front of the pistol grip needs to be more vertical than most of the older rifles but again it's a question of what feels right for the individual. A couple of examples attached - first my Sako Quad in .17 HMR and second my Sako A2 action in .243 - Given the time again I would have reduced the depth of the cheekpiece on the Quad - it seems about right (to me anyway) on the Sako .243 - my apologies that the photo of the .243 is upside down but I do not know how to turn it the other way up.
