 "Fabric
Covering with Ray Stits"
The Master, the man who invented the
Poly-Fiber
system (formerly know as the Stits Poly-Fiber Aircraft
Covering process), takes you on a VHS tour de force through the wonderful
world
of fabric covering. Here's two hours of how to do it
correctly, how to do it incorrectly, plus some of Ray's dramatic ways
of making a point.

 SELF-TAPPING METAL SCREWS
Low profile, slot head, type A, pointed
end. Used on some aircraft models to attach fabric to metal wing ribs
and empennage ribs in lieu of rib lacing.
|
|
 ALUMINUM REINFORCING WASHERS
Recommended in substitute for original
plastic washers under screws and pop rivets where fabric is anchored to
metal wing rib or empennage ribs. 2024-T3 aluminum, .128 hole x 1/2"
outside diameter x .016 thick.

|
 SEWING NEEDLES
CURVED: 3" and 6" for hand
stitching.
STRAIGHT: 12" and 18" rib lacing needles.
CURVED TIP: 12" and 18" for the hidden rib
lace knot illustrated in the Poly-Fiber Procedure Manual.
|
|
 T-HEAD PINS
Bright, polished, corrosion resistant
steel. 1-3/4" length. Used to temporarily secure
fabric in place when recovering aircraft surfaces, upholstery,
furniture, etc. 475 pins per 1/2 pound box.
|
|
 PAINT STRAINER CONES
Fine mesh, 60x48, for filtering all
pigmented finishes, Poly-Brush, Poly-Spray, varnish and other liquids,

action. Use with liquid detergents to clean all metal and painted
surfaces.

GLASS THERMOMETER
Mercury, Laboratory Grade, TCA #6357, 30
degrees F to 400 degrees F, in 2 degree increments, 14" long. Used for
iron calibration and any other applications requiring accurate
temperature information.
|
|
SILICONE
HEAT SINK COMPOUND
For more accurate thermo transfer during
iron calibration.
