1. Assemble the elevator core (EC) from two parts. This and the following steps are best done over a sheet
of parchment paper. This material is available in your local grocery store in the baking department. Hey, if
chocolate chip cookies won’t stick to it, glue doesn’t stand a chance. I digress.

2. With the core sheet flat on the bench, install all split ribs starting
from S1. Hold the core sheet flat while applying thin CA.

13. Assemble the elevator sections. Note that one elevator core also contains a ply plate to attach the horn to.
Keep this in mind when hinging to get it on the desired side.
□
3. When all ribs have been installed, install the trailing edge. Hold
the trailing edge in place with the straight edge of a ruler or other
straight edge while applying CA as shown in the photo at the right.
This will keep the assembly straight.
□
4. Turn the assembly over and install all ribs on the opposite side.
Apply finger pressure to the ribs to keep the assembly flat and
make good contact with the parts.
□
5. Assemble both stabilizer skins and sand out any irregularities. For the next step you will need some spring
type cloths pins or other means of providing even pressure along both leading edge halves. Cloths pins work
best.
□
6. Use a straight edge or a straight board on the bench to butt the stabilizer skin up against for the next step. If
you can just butt the assembly up against the straight edge and then bring it into contact with the skins the
next step is much easier to do. Place one of the skins on the bench with the trailing edge butted up against
the straight edge. Now apply aliphatic resin glue to all the ribs on one side of the stab assembly. Next apply
a liberal bead of thick CA along the trailing edge. Flip the assembly over and but it up against the straight
edge and then bring one half down into contact with the skin. Apply pressure until the CA sets and then rock
the assembly over and apply pressure to the other half.
□
7. Turn the assembly over immediately and repeat the process for the opposite side.
□
8. Now apply a cloths pin about every inch along the leading edge check the assembly for straightness before
the next step.
□
9. Hold the assembly on end and apply thin CA to the leading edge at the tip. Allow it to run down the leading
edge between the sheeting until it reaches the center. Now flip the assembly over and repeat the process for
the other half. You can now glue the tip sections by just squeezing them together and applying CA. This
concludes the assembly of the stab section. Trim and sand to finish.
Fin Assembly
□
1. Use the same technique as the stabilizer, lay
the core sheet flat on the bench and install all
the split ribs on one side. Install the trailing
edge with a straight edge as before. Trim the
corners off of the leading edge of each rib to
align with the leading edge and install the
leading edge.
