Continuing on with the general description of the Spitfire MKI-V rudder fabric covering process. Using the Polyfiber system, we used Poly-Tak to attach the fabric on one side of the rudder and secure with clamps until dry, to the trailing edge, this includes wrapping the fabric around the edge as can be seen in the photos below. This provides a solid bonding of the fabric to the rudder structure, allows to align the fabric and fold it around the leading edge of the rudder, thus eliminating a seam, while continuing the fabric back again to the other sides trailing edge. To secure the fabric you will apply the Poly-Tak to complete the rough laid fabric covering and let the glue dry. You will also notice it is not necessary to pull the fabric tight, but you will want take out any folds and minimize creases as you lay the fabric down on each rudder side, since this will avoid big problems down the road. The fabric itself will be later heated and shrunk bringing the fabric to its proper level of tightness in later posts, so stay tuned and enjoy!
Just for fun I also included a shot of the Spitfire rudder showing the fabric with some pretty serious creases...not to do...but it will show to the level of what you can work out down the road if a mistake is made, and not have a panic attach!
