S-7S COVERING
GENERAL INFORMATION
Read this entire section before starting to cover.
The following additional supplies will be required to cover the S-7S.
•
Pinking Shears
•
Regular Scissors
•
Razor Blades
•
Covering Irons
•
Covering Thermometer
•
2" Brushes
•
Containers for Glue and Solvents with lids
•
Saw Horses or “A” frame pivot stands
•
Methyl Ethyl Ketone (MEK)
•
1/4” double-stick tape
Buy a pair of rotary pinking shears. They will be used to cut all the patches and
tapes. The rotary style is so much better than the normal scissors type “pinkers”.
It is money very well spent.
Neatness and cleanliness during the covering process will reflect in the finished
product.
CAUTION: Adequate ventilation is necessary. You may want to obtain
the SuperFlite aircraft covering manual from SuperFlite before proceeding.
Before shrinking any fabric, calibrate your covering irons as described. A model
airplane iron is also useful in shrinking up tight areas. A regular clothing iron may
be used for over all shrinking. The best ones are the old Steel irons. New irons
are usually made of Aluminum. They just do not have the mass to work like the
old fashion irons. Look for an iron at a garage sale or second hand store, or
borrow grannies.
Another problem area is curves. The fabric will want to wrinkle when being glued
to a curved corner, like the ones on the tail. The SuperFlite manual points out a
slick way to glue down wrinkle free corners. Refer to the manual for basic
covering technique.
RANS currently uses SuperFlite U-500 glue, thinned with MEK when required. U-
500 will also be used to seal fabric or glue down tapes and patches. References
may be made to applying a coat of glue over the entire surface. In general, we do
not recommend this, since it prevents adhesion of the base primer coat. Double
coating is normally only required in areas of tapes, patches, or underlying sheet
metal surfaces. This coating will prevent pinholes.
