With the skins rivetted and the internal structure and rivets primed/touched-up, the rear spar was clecoed into place - looking good. Gem insisted i got into the picture, looks like I'm checking something out, but I'm not really.
Rear spar is a doddle to fit with the squeezer, took about 15-20 minutes with Gem's help removing clecos and putting rivets in the holes as you move along. Pic 2 shows the finished top surface.
Not to be outdone, I sneakily got Gem into the pics, she hates having her pic taken, so for no other reason here she is at pic 2 priming the Rear spar to HS601PP rivets and touching up the primer where the dirty fingers have been!!.
