Aileron/Flap Hinge Installation
❏
Draw the chord lines on the forward and aft face of the aft wing spars.
❏
Draw the wing stations on the aft face of the aft wing spar. See Drawing No. 206.
❏
Draw the wing stations on the forward face of the aileron/flap spar. See Drawing No. 206.
❏
Lay out the locations of the “hinge opening” leading edge ribs on the front face of the
aileron/flap spar. These ribs do not fall directly on a wing station and should be laid out
prior to the installation of the hinges. See Drawing No. 203. As you can see from
Drawing No. 206, the stations on the aileron/flap spar are actually 253mm per 250mm
wing station, thus the growth of horizontal dimensions is very small. You can see all of the
interference/clearance problems for these leading edge ribs on Drawing No. 204
❏
Ream all 1/4” hinge bolt bushings with 1/4” reamer. (See Drawing No. 204 for the
following steps.)
❏
Install all tapered plywood hinge pads on the aft face of the aft wing spar.
❏
Install all 1/4” hinge bolts in the hinges and assemble the hinges together.
Note:
To align the aileron and flap hinges, a number of builders have found it helpful to
use a long 1/4ӯ steel rod. Others have used threaded steel rods or wooden dowels for the
same purpose.
❏
Clamp all hinges in position on the aileron, flap and aft wing spars. Check to make sure
that the hinges are working smoothly and that all hinges are correctly located.
Note:
The drawings show P/N 746 installed with the bolts inboard. Some early builders
reported that there wasn’t enough solid wood in the spar for this, so they switched the L.H.
and R.H. hinges and installed the hinges with the bolts on the outboard end. There is
really nothing wrong with doing this, but it will make the two 3/16” nuts difficult to reach.
❏
Remove the hinge bolts and drill the 3/16” bolt holes for P/N 743.
Note:
It is always best to drill such bolt holes with a drill press; however, you will find it
easiest if you use a hand-held drill to start the hole, then remove the hinge and complete
drilling the hole with a drill press.
❏
Install the channel-nuts for P/N 743. Do not install the screws for the channel-nuts at this
time.
❏
Re-assemble the hinges with the hinge bolts and check for smooth operation of the hinges.
❏
Remove the hinge bolts and drill the 3/16” bolt holes for P/N 748.
Note:
Plywood pads are installed under the channel-nuts to make the bolt lengths come
out right. These will be installed after all of the hinge bolt holes are drilled.
❏
Install the channel-nuts for P/N 748. Do not install the screws for the channel-nuts at this
time.
