(10-4 steps 1 & 2):  As we were tearing down the remaining pieces of the tailcone the other day I noticed the #12 holes we drilled in the horizontal stabilizer attachment angle… they bugged me.  They seemed way to close to the edge of the angle.  I set it aside… but it kept bugging me.  Well, since I had another piece of angle I decided to go ahead and cut another one.  I cut this one about 1/4" longer thinking I'd sand the edges down to a perfect fit.  I took my time making sure to get all the holes perfectly positioned... first I match drilled the frame holes using the existing angle to get the height just right.  Once those holes were drilled and the angle was clecoed to the frame, I clecoed the assembly to the longerons, the aft deck, and the F-1010B spacer that goes between the angle and the aft deck.  I then used a couple of #30 drill bits to line up the holes in the aft deck and spacer and then clamped these to the angle.  Next I match drilled the four #30 holes of the aft deck into the angle.

(10-13 steps 3 & 4):  After that I started to match drill the #12 holes that go through the longerons, but only drilled far enough to give a small dimple to use for positioning the #30 drill bit.  After #30's were drilled through, then I opened the holes to #12.  Here you can see the before and after result.  As you can see, the #12 bolt hole is quite close to the edge on the first angle we did.  The second attempt makes me feel a quite a bit better.  The interesting thing is I didn't have to sand the new angle to fit like I originally intended... it fit just fine as is!  A quarter inch longer (about an 1/8" longer than the plans call for) and it fits just fine!
