Step 1.   The plans tell you to check the angle of the spar flanges to the spar web.  The forward spar should be 84 degrees and the rear spar 96.  Unless you build yourself a jig that goes inside the spar, this is only good at the spar ends, so I need to build said jig.  I'll do this prior to priming to make sure. 

Step 2.   Dimple the two holes in each of the inner E-1022 shear clips, as shown.

Step 3.   Dimple the holes in the flanges of the E-1006 rib halves to accept the skin dimples.  Set up the pneumatic squeezer in your vise and this goes real fast.

Step 4.   Dimple the two #40 holes in the web of the E-904 above the #30 holes.  If you accidentally have no brain at this point and do the two at the opposite end, well, then you have 4 dimpled holes and you'll have to dimple an extra two in the E-903, etc.   Don't forget to put on your brain, which from time-to-time I seem to neglect.  At any rate, dimple the holes in the E-903 that correspond to all the holes you just dimpled in the E-904.

Step 5.   Dimple the top and bottom flanges of both the E-903 and E-904 tip ribs for the skin dimples.  This is easy except for the last two holes on either flange of the E-903.  It gets tight down at the tip, so you have to improvise a little.  I took my pop rivet dimple set and a c-clamp and got dimples, but not as good as they need to be.  I'm going to have to get them to dimple more, somehow.  I got this idea from Experimental Aero.   You have to modify the c-clamp by grinding down the top ridge to get it to fit at the narrowest point.

Step 6.   Machine countersink the holes on both sides of each E-1023 trailing edge.  Best to use a jig, as shown in the picture, that holds the wedges perpendicular to the countersink bit.  Use the drill press.  This is a must.  Goes fast, once it's all set up.  Make sure you check every third or fourth countersink, however.  These cages often do not hold their setting.

Step 7.   Put a slight bend inward on the trailing edges of all four E-1001 skins where they go over the F-1023.  I couldn't get good results with my Avery edge tool, so I took the advice given in Section 5K and used a wood block.  It seems to have worked okay.  The Avery tool would go over the dimpled holes and not make a clean bend.

Step 8.   On the inside of each E-1001, mark where the foam ribs are to go, and scuff the skins so the adhesion is improved when you glue them in place with proseal.  In order to do this, I went ahead and cut out all the foam blocks, those for the elevators and those for the trim tabs. Might as well. Then I left the protective plastic in place on the skins, marked the location of the ribs, then removed the plastic where the ribs are to be placed.  I then scuffed that part, cleaned and moved on.  Check to make sure you're using aluminum oxide sand paper.  150 grit.
