3. Cut a groove in the LE of the elevators and drill 3/32"
[2.4mm] holes where you made your marks to accommodate
the elevator joiner wire.
Hint
: Use a 3/32" [2.4mm] brass tube
sharpened at the end to cut the groove. (The Groove Tube
™
Grooving Tool (GPMR8140) works great for this task.)

4. Use 30-minute epoxy to glue the elevator joiner wire
into the elevators. Use a straightedge as shown in the photo
to align the leading edge of the elevators. Use weights to
hold the elevators in position until the epoxy cures.

1. Cut twelve 3/4" x 1" [19mm x 25mm] hinges from the
CA hinge strip supplied with this kit. Snip the corners off so
they go into the slots easier. You may cut all the hinges now,
or cut them as you need them.
❏
2. Test fit the elevators to the stab. If the hinges are
difficult to install or don’t go in far enough, carefully enlarge
the hinge slots with a hobby knife and a #11 blade.
❏
3. Drill a 3/32" [2.4mm] hole, 1/2" [13mm] deep, in the
center of the hinge slot. If you use a Dremel® MultiPro™ for
this task, it will result in a cleaner hole than if you use a
slower speed drill. Drilling the hole will twist some of the
wood fibers into the slot, making it difficult to insert the
hinge, so you should reinsert the knife blade, working it
back and forth a few times to clean out the slot.
❏
4. If the hinges don’t remain centered, remove the
elevator and insert a pin in the center of the hinges.
Before you glue in the hinges, apply a few drops of
household oil to a tissue. Wipe the tissue over the trailing
edge of the stabilizer and the leading edge of the
elevators, coating them with a fine film of oil. This will
prevent excess CA from sticking to the stab and elevator
at the hinge gap while you are gluing in the hinges.
