| Step 1: Deburr the edges
(including the lighten holes ) of the
HS-1002 Front Spar. 01/13/08 |
|||||||||||||
| Step 2: The
HS-1013 Front Spar Caps are nested in the corners of the HS-1002 Front Spar
with the trimmed flange of the spar cap resting against the spar web. On
one of the spar caps make a mark on the flange (the one that rests
against the flange of the spar) a quarter of a inch from either end.
Nest the spar caps in the spar, then from the corresponding end of the
spar, center the mark in the thirty-third hole. ( make sure it covers
the same hole from the other end) Clamp the spar cap in place, then match-drill the 1/8" holes of the spar web into the entire length of the spar cap with a #30 drill. The spar cap is somewhat bowed as supplied, so use plenty of clamps to make sure the spar cap is tight against the spar web and flange while drilling. Remove the spar cap, deburr the holes of the spar and spar cap, then cleco the spar back in place. It's important to deburr and clean out any chips, otherwise the spar cap won't fit tight against the spar web when match-drilling the spar flange holes.
Clamp the spar cap to the flange of the spar, then match-drill the 3/32" holes of the spar flange into the spar cap with a 3/32" drill. Repeat this step for the second spar cap. 01/20/08 |

| Step 3: Deburr and smooth the edges of the HS-1007 Front spar Doubler and the HS-1008-L and HS-1008-R Front Spar Attachment Brackets, then cleco them to the HS-1002 Front Spar as shown in Figure 1. | |||||||||||||
| Step 4: Clamp something
flat to the bottom of HS-1008-L and HS-1008R Front Spar Attachment
Brackets to keep them Square to each other, then match-drill the eight
holes of the spar and spar doubler into the attachment brackets with a
#30 drill. Cleco a few of these holes, remove the original, single
cleco, and final-drill the hole with the same drill.
