This is the floor after drilling and countersinking all 120 nut plates!! I found a large collection of shavings in the house as well. I forgot to take any pictures of the inspection plate nut plate instalation, sorry.
The tie down bracket. I have a few things to say about these. First, the only reason that you need to make them removable is that the bell crank needs to be in postion prior to mounting the brackets on the front side of the spar. The noise in the instructions about if the nut plate is damaged is a bunch of crap (IMHO). The easyest way to build these is to drill the first hole and then clamp the bracket at the other end. Drill one hole at the clamped end and then bolt both ends on and get rid of the clamp. After that back drill all the remaining holes except the nut plate rivet holes. Then put the shims under the bracket , clamp and drill them. Bolt them on using the nut plate and then drill the rivet holes right thru the nut plates. Use a drill stop to keep from hitting the spar. Remove debur countersink prime and install but do not put the aileron brackets on now as you will just have to remove the later.
Both brackets built but not primed yet. I still need to prime the spars where I cut countersinks as well.
