Today, I drilled out every hole that had a cleco in it from the previous post. This cleans out the hole and makes it easier for the rivet to go in. I then disassembled the structure and drilled a few remaining holes in the spar. Next, I cleaned the shop and started assembling the left horizontal stabilizer. I only clecoed together the left skeleton and cleaned out some holes. Next will be to put the skin on and work on the inner rib fitment.
