Image is slightly blurred but still illustrates the drill through principle I used on this 'tricky if you get it wrong stage' of the build.
A replacement bolt, nut and spacing washers will be used to secure the elevator horns together via the bearing. The nut head's have just enough space to avoid the weld seam, but not too much!
The canopy track is drilled through the fuselage then clecoed in place.
The rear canopy bow is slotted into the white UHMW fitting (just visible) to ensure the canopy locks into position correctly.

A string is place from a temporary fitting at the rear of the VS and measured equally from a centre point.
The string is also attached to a forward centre point on the fuselage. When both strings are equally distanced from the VS it's deemed centralised!
This shows the port side of the VS alignment procedure
This is the underneath of the previous items. You can see there is very little room to manouvre. The hole 3/16 must be place 1/2" from the outer edge of the longeron so it's very tight indeed.
This is a tricky operation with the turtle deck inplace. It's a critical component, in an inaccesible place. Plans require great scrutiny to place the holes precisely and squarely through the parts required compliant with the MED. The Red item is the plastic base of one of my clamps! The swarf is just there to add dramatic effect.
