ZOR,
I do not disagree with you but the height of the elevator is dictated by the plans so therefore I had five axes to deal with. All of the other items you have defined are within spec as it sits right now.
I also checked and double checked each measurement before I locked into place.

The nice thing about building a wood Tipo is that the datum line or tuck line happens to be the stab incidence line as well. This makes incidence adjustment and/or measurement less of a task than it may be otherwise. In some classics, the stab is located so their chord lines sit precisely on the "fuse top" with a fairing to encompass the space between the vertical and the stab top airfoil (e.g., the Blue Angel).
On the glass Tipo, the tuck line is harder to establish because curvature is molded into the fuse. When building a wood version, the tuck line can be inscribed on the fuse sides and then the curvature is produced about it. Since the fuse sides are flat about 9" from the stab LE, the tuck line can be preserved and used as an incidence reference when installing the stab.
