I've been doing a lot of HS riveting now that all the parts are primed:

All the primed parts from last week, plus spars (priming and riveting done some time back) |
I started by riveting the inboard ribs plus stringers, then attaching those to the front spar:

Stringers / most inboard ribs riveted to the front spar |
Next was adding the other inspar ribs (except the outboard 2) and rivet them as well:

All inboard ribs riveted to the spar/ribs/stringers assembly |
The nose ribs were riveted to the skins (a bit challenging given the little clearance for the bucking bar):

Riveting the nose ribs into the skins |
The front spar assembly is then inserted into the skins:

Spar/rib assembly inserted back into the skins |
It is riveted to the nose ribs using a mix of solid and pop rivets:

Pop rivets to attach the front spar to the nose ribs |

Rivets attaching the inboard nose ribs to the front spar |
Then the last 2 outboard ribs are added and riveted (one with pop rivets, the other with solid ones):

Outboard inspar ribs riveted |
The next step is riveting the entire front spar to the skin, which was a lot of work (over 180 rivets):

Those front spar rivets behind the stringers were annoying to reach with the bucking bar |

Nose ribs and front spar riveted to the skin |
There are a few rivets left to do on the left bottom skin to front spar attachment, then I'll start riveting up the inspar ribs.
Time lapse:
Total horizontal stabilizer time: 109.4h
Total horizontal stabilizer rivets: 491
