Built Rudder jig and mounted the forward and aft spars and lower rib. The Builders Manual suggested using nails, string and a plumb bob to align the components accurately. This all assumes that your table is perfectly plumb, square and level, which in my case was going to be very hard to achieve (see section on wing jig). The main requirement is that the components are aligned relative to each other and not to an absolute datum. Consequently I was able to use a laser straight line generator placed farther down the table to beam a reference line (actually a reference plane) through all the major components. This worked very well.

Finished aligning and drilling all rudder components. The whole assembly is very flexible without the skins. Consequently, alignment of the counterweight rib is very difficult. The counterweight rib is held in place by 2 brackets connected to the forward and aft spars. The drilling of these brackets required a right-angled drill an ultimately proved quick trick and lead to a slight misalignment of the counterweight rib. This was confirmed by the laser line generator. I'm not sure how exact this alignment has to be, but time will tell how critical this alignment is.

All parts where disassembled and deburred ready for priming.

Constructed counterweight rib lead weight designed to stop "flutter" of the rudder.

The special primer from NewGlastar had not arrived so the parts will be primed later and I moved on to the Horizontal stabilizer.

Now that all the internals have been corrosion protected, the fun part starts - riveting!  This is my first riveting experience and is a bit nerve racking at first because you only get one shot at it.  I made slow but steady progress on most of the internals of the rudder.  I got to use the pneumatic squeezer and the rivet gun / bucking bar on both 3/32" and 1/8" rivets.

Finished riveting the rudder skins in place and installed and riveted the front skin and tip rib with accompanying nut plates.  Many rivets where very hard to get to properly with a bucking bar but perseverance paid off eventually.  Riveting is taking a lot longer than I thought it would, but it's very satisfying to watch it come together.
