The December Meeting Minutes -
We met at the Wonderful Chinese Restaurant for a
delicious meal and chit chat. I do not hear all that well but I think
that everyone had a good time. no "business" was transacted.
Model of the month.
Two things this month! Neither is a model, oh well.
is a "Single Blade Free-wheeling Prop" by Donald Mertens, Page 33, MAN
Oct 1940. No blade layout, just features for balancing single blade
prop and employing a free-wheeling drive. Plans follow.
Second is man carrying tandem glider from
Boy Mechanic, 1914, HH Winsor editor. All detail design is absent.
The wings have no control surfaces and dihedral is not employed. The
"pilot" is shown well aft of the center of lift. This could be a safety
feature. If there is a wind blowing, the glider should rear up and
blow over backward while still on the ground. When I was a kid I wanted
a foot launched glider, fortunately I could not afford the material but
I could get to the library and read books all the way back to Octave

- my (Ken speaking) garage was burgled and among other things much of
my IC model stuff was taken. I am bummed out needless to say. A lot of
that stuff was irreplaceable in the 21st century, as you all well know.
My sense of balance just took another hit so I think it is time to
move up to gum band FF. Crashes only hurt the ego of the rubber band
bunch. I know, I know, gum bands are expensive but if purchased a
quarter pound at time and wound to less than 70% of max they last for a
couple of dozen flights making it reasonable.
Now on to the aviation stuff!!!
Tandem Monoplane Glider
By George F. Mace
monoplane glider illustrated has better fore-and-aft stability than the
biplane, is lighter in proportion to the supporting surface, simpler to
build, and requires very little time to assemble or take apart. The
material list is as follows:
4 pieces of bamboo, 14 ft. long, tapering from 1-1/2 to 1 in.
8 pieces of spruce, 1/2 in. thick, 1 in. wide, and 3 ft. long.
8 pieces of spruce, 1/2 in. thick, 1 in. wide, and 2 ft. long.
4 main-wing bars, spruce, 3/4 in. thick, 1-1/4 in. wide, and 18 ft. long.
8 wing crosspieces, spruce, 3/4 in. square, and 4 ft. long.
38 wing ribs, poplar or spruce, 1/4 in. thick, 3/4 in. wide, and 64 in. long.
The first thing to do is to make the main frame which is composed
of the four bamboo poles. The poles take the corners of a 2-ft. square
space and are supported with the pieces of spruce that are 2 ft. and 3
ft. long, the shorter lengths running horizontally and the longer
upright, so that each upright piece extends 1 ft. above the two upper
poles. All joints should be fastened with 3/16-in. stove bolts. The wire
used to truss the glider is No. 16 gauge piano wire. The trussing is
done in all directions, crossing the wires between the frame parts,
except in the center or space between the four poles.
The Start of
the Glide should be Made from the Top of a Hill, Then a Little Run will
Carry the Airman Several Hundred Feet through the Air
The framework of the main wings is put together by bolting one of the
crosspieces at each end of two wing bars, then another 4 ft. from each
end, whereupon the wing bars are bolted to the main frame. The frame is
then braced diagonally between these pieces. The ribs, spaced 1 ft.
apart, are fastened to this frame with 1-in. brads. The ribs are so bent
that the highest part will be 5 or 6 in. above the horizontal. The
bending must be uniform and is done when fastening them in place.
The material used to cover the wings and rudders is
strong muslin. The cloth is first tacked to the front wing bar, then to
the ribs, and sewed to a wire which is fastened between the ends of the
ribs. Large brass-head tacks should be used through a strip of tape to
fasten the cloth to the ribs. The rear wings are constructed in a
similar manner. After the cloth is in place it is coated with starch or
Tandem Monoplane Glider, Showing the Main Frame and Wing Construction,
and the Manner of Placing the Crossed Bracing Wires Between the Parts
and to the Wing Ends
vertical rectangular spaces in the main frame, just under the rear
wings, are covered with cloth to act as a rudder. The upper and lower
bracing wires for the wings are attached with snaps and rings so that
the glider can be easily taken apart.
It is best not to use the glider in a wind greater than 30 miles an
hour. It is started from the top of a hill in the usual manner. Glides
can be made running from 60 to several hundred feet.
