 Step 1:
The T-1005B and T-1005C Shims are provided as a single
piece of metal with the parts "tabbed together". Separate
the shims from each other, file-off the tabs, and deburr the
edges. |
| |
 Step 2:
Final-Drill holes in T-1005B and T-1005C Shims. Use
a #40 bit for the small holes; use a #19 bit for the large
holes. Deburr all the holes. |
| |
| Step 3:
Study Figure 1 until there is no question as to the position
and/or orientation of each part or hardware item. |
| |
 Step 4:
Dimple the two #19 holes in the T-1005B Shim which will
have K-1100-08 Nut Plates attached. |
| |

Step 4A: Dimple the K-1100-08 Nut
plates and the corresponding nut plate attach rivet holes in
the shim. |
| |

Step 4B:
Rivet the K-1100-08 Nut plates to the shim as shown in Figure 1. |
| |
 Step 5:
Attach the VA-146 Bearing, K-1000-08 and MS21051-L08 Nut
Plates, and T-1005B & C Shims to the T-1005-L Tank Attach
Brackets as shown in Figure 1. |
| |
 Note: Assembly steps
from this point on require that sealant be installed between
mating parts.
Read Section 5S for more information
on fuel tank sealant.
The tank is riveted together just
like any other structure with one very important difference:
Apply sealant between the parts comprising a seam through
which fuel could conceivably leak. This includes every
rivet. |
| |
 Step 2: Fabricate
and install small plates made from scrap .025 or .032
aluminum to close-off the 3/16 diameter holes in the webs of
the T-1003-L Tank Outbd Rib, T-1003B-R Tank Inbd Rib-Aft,
and T-1003C-R Tank Inbd Rib-Fwd. These holes are used to
hold the ribs and formblocks in proper alignment during
hydro press forming of the ribs. |
| |
| Step 3:
Attach the VA-141 Finger Strainer Flange, T-1010
Anti-Rotation Plate, and Nut Plates to the T-1003B-L Tank
Inbd Rib-Aft as shown in Figure 2.

Step 3A: Spread Pro-Seal
on Finger Flange parts. I used some vinyl fine line
tape that stretches to make a circle around it to contain
the edge |
| |
 Step 3B:
Pulled tape off, smoothed the edges and cleaned it
thoroughly including the threads |
| |
 Step 3C:
Cleaned and taped the anti-rotation plate |
| |
 Step 3D:
Spread sealer and riveted the plate |
| |
Step 4:
Rivet the T-1011 Stiffeners and VA-112 Drain Flange to the
T-1001-L Tank Skin as shown on page 18-2, Figure 4. See
Figure 3 for rivet call-out. (Note:
See pictures below for how I did it.)
Recall that two
stiffeners on the bottom of the most inboard rib bay have
been shortened to all water accumulation to migrate aft to
the drain point

Step 4A: Cleaned area
ready to rivet. I used some pre-taped masking paper to mark
area for pro-seal and contain the mess. |
| |

Step 4A1:It comes in a roll and is
easy to tear off the amount you want. |

Step 4B: Smeared
Pro-seal on the parts to be joined |
| |

Step 4C: Stiffener in
place and ready to back rivet |
| |

After riveting smooth the edges to seal with wooden
stick. |
| |
| |

Step 4D: Stiffener
riveted in place and masking paper removed. |
| |

Step 4E: The Pro-Seal has
come through around the rivets, so I think it is going to be
a good seal. |
| |

Step 4F: Pulled rivet tape off and
check to see if rivets were flush; Some where still a little
high so I hit them with the flush rivet gun and a bucking
bar and they seem OK. Even using the special die I found
that the holes need to be pretty deep to allow the room for
the Pro-Seal. I hit them a couple of turns with the
deburring tool just before putting in the rivet and that
seemed to work better. |

Step 4G: |
| |

Step 4 Drain Flange: |
| |

Step 4 Drain Flange1: One of the
tools I bought awhile back was a Long squeezer yoke and it
has come in handy and worked well to reach the rivets here. |
| |
|
Step 4 Drain Flange2: |
| |
| Step 5: Rivet
the T-406B Fuel Cap Flange and T-1008 Vent Clip to the
T-1001-L Tank Skin as shown on page 18-3, Figure 2. See
Figure 3 for rivet call-outs.

Step 5A:
Again I started by cleaning and taped the area to be sealed |
| |

Step 5B: Spread Pro-Seal on flange
and skin and clecoed together. It looks like it is spread
well and you can see some of it starting to come out around
the edge of the opening. |
| |

Step 5C: Taped over rivets and
bucked |
| |

Step 5D: Pulled tape and smoothed
seal over back of rivets |
| |

Step 5E: Cleaned around the rivets
and the flange where it meets the skin. I can see a bead of
Pro-Seal all the way around the gap so I think it is sealed
pretty well. |
| |
| |

Step 6: Rivet the T-1003C-R Tank Inbd Rib-Fwd, T-1004-L Tank
Interior Ribs, and T-1003-L Tank Outboard Rib, to the
T-1001-L Tank Skin as shown on page 18-2, Figure 5. See
Figure 3 for rivet call-outs. Note:
Again I started by cleaning and taping the area to be
sealed, this is the Inbd-fwd rib described as the one to
start with.
Begin with the tank
Inbd rib-fwd and progress from inboard to outboard,
finishing with the tank outboard rib.

Step 6A: Squeezing the
rivets in the nose rib.

Step 6B: Spread Pro-Seal
along the rib and over the rivets

Step 6C: Started to prepare
interior ribs for sealing

Step 6D: First interior
rib riveted and sealed in place. Note: This page is
getting a little long but I have found a sequence that I
like doing on the interior ribs, so I added a page on how I
am doing it. To see it click here |

Started organizing left wing to work on bottom skin.

Here it is flipped over. It looks like using the table
to rivet it on will allow pretty good access.

The shop is getting a little disorganized, and I am starting
to spend to much time looking for things, so I am re-doing
shelf's. One great thing about slot board is it lasts
forever and lends itself to changing displays around.
Got all the parts sorted according to what parts
of the various components they are used in, Flaps, Ailerons, Wing, etc. |

Laid wings out across the shop to position right wing
to start working on with fuselage in center. This airplane
is going to be a Big, Nice Aircraft with plenty of room for
me in front. I am a 6'2' and weight to much (280) |
