Horizontal Stabilizer Skeleton Prep

 Started tonight by adding a radius to the tip of the nose rib flanges.  Suppose to help keep the distortion of the skin to a minimum.

 Next I cleco'ed on the inner most inspar ribs and the tip ribs to match drill some holes with the spar.  They have you do this with a smaller 1/8" bit first.

 Here they are all match drilled to the spar.

 Then you go back and finalize the holes.  I used a #30 reamer to do the nose ribs.

 And a long #30 drill to do the inner most ribs.

 Next they have you cleco on the inspar ribs.

 Then I match reamed them to the spar.

 Here it is all match drilled/reamed.

 I went ahead and fluted the ribs.  See the curve in the rib?  These special pliers do a great job putting a little flute in between the holes on the rib flange.  A light squeeze at each location top and bottom is all you need.

And like magic, the rib is straight!

That's all for tonight!
