| NOTE; The trailing edge of the
elevators will bonded and riveted like the rudder trailing
edge in Section 7, except that the two foam ribs are
bonded in place as well. Note
we are not going to bond the trailing edge but rather use
the full length bucking bar like we did on the rudder. It
produced a nice straight edge for us.
Another builder used our idea and improved on it
and has written a very excellent description of the process.

Step 7: Cut four trailing edge
ribs from the PVC-750 X 2 X 5.25 blocks supplied in the
kit. Glue the templates, found on the last page of this
section, onto the blocks using a spray adhesive Cut the
ribs from the blocks, then
using a sanding block t finish the edges exactly to the
template lines.
A
band saw works well here |
|
| Step 8 thru Step 12: describes
how the bonding method is done. We will describe how we
did it with the bucking bar. |
|
| Step 13: Rivet
the trailing edges |

Step 1: Finish
riveting the E-1001 Skins to the flanges of the E-903
Outboard Tip Rib, aft of the rear spar, using the rivets
called out on page 9-20, Figure 1 & 2
|
|
Step 2: Rivet
the Shear Clip to the E-1001 Skins using the rivets shown
in Figure 1. Install a blind rivet in the remaining hole
in the close out tabs aft of the shear clip.
|
|
| Step 3: Make a
slight bend along the leading edge of the E-1001A Top Skin
so it lays flush on the E-1001B Bottom Skin after rolling
and riveting. |
|
Using duct tape to attach 1 1/4"
pipe to the skin
Step 4: Roll
the leading edge of the E-1001 Skins in the same way as
the rudder. Again, use a 1-1/4" diameter pipe, and
begin rolling the section of the skin closest to the tip
ribs.
|
|
Step 5: Cleco the
leading edge together with the E-1001A Top Skin on top of
the E-1001B Bottom Skin, then final drill the holes along
the leading edge with a #30 drill.
|
|
Step 6: Secure
the leading edge with rivets shown on Page 9-20, Figure 1
|
|
| Step 7: Rivet the
two WD-415 Trim Cable Attachment Brackets to their corresponding
E-616 Cover Plates using blind rivets called out in Figure
2. Place the head of the rivet on the cover plate. |
|
Step 8: Remove
material indicated by the shaded areas in the left drawing
of Figure 3 from all four E-614 Counterweights. Notice
that the two holes are closer to the bottom edge in the
drawing, so be sure to trim the weight accordingly.
Remove the raised portion on the back side of ONLY
TWO of the counter weights. This portion is indicated by
the shaded area in the right drawing. |
|
Step 9: Attach
the counterweights to the tip ribs using the hardware in Figure
4. Notice that the counter weight without the raised
portion is attached to the inboard side of the ribs. This
weight is thin enough to completely nest within the
overhang E-913 Counterbalance Skin, thereby maintaining
the required clearance with the horizontal stabilizer when
the elevator is attached to it.
