Project Update -
The following are some of the latest areas I have been making
progress on with my scratch building project:
TRIM CONTROL
I'm going with a trim tab. The trim tab is literally
built in place in the elevator, then cut away. I'll use
a piano hinge however I hope to attach the hinge
on the vertical surfaces of the tab and elevator
using pull rivets, and this will be done after
covering this surfaces.
I have the trim control handle roughed out as shown.
The handle needs to be cut shorter, then a bolt needs
to be welded to it to receive a phenolic knob.
A push-pull control cable is attached to the handle
and to the tab at the elevator. A bolt gets welded to
the pivot on the handle, through a steel bushing welded
to the fuselage with an oilite bearing pressed into the
steel bushing. Appropriate washers will be used for
friction surfaces, and a castle nut will be used to tension
the bolt for proper friction.
Here's a photo of the push pull control cable running
along the fuselage. It seems that running the cable
inside the fuselage stringer may work well.
BAGGAGE DOOR FRAME
Baggage Compartment Door Frame located
on right side. It's about 10" tall x about 16" long.
I wonder if it's big enough?
I bent up some 0.020" steel into c-channel shapes
for the top and sides. I tried to paint a little primer
inside the channel and on the fuselage tubes
prior to welding in place. The bottom frame piece is a
piece of steel completely folded over itself, with a
generous radius on the outer edge to match the
shape of the stringer. Folding the piece over with the
radius makes it very stiff. I'll use a piano hinge along
the bottom to hold the baggage door in place.
I'm using aluminum hat shape material for the
stringers on the sides of the fuselage. I may simply
epoxy them into place to omit the need to weld tabs
on, but that is yet to be determined.
A better idea of the size of the baggage door.
When looking through my photos recently, I came
across this one I took during New Holstein 2013.
I thought folks may like it...
Thank you for looking, John
