Welcome back to the continuing Tally-Ho Spitfire rudder build, in the hangar fabric shop being covered. So previously we glued on the fabric as per the last post, and now we came to the really fun part of the fabric covering process...shrinking the fabric!!! This is where it really feels it's coming together. Using a calibrated iron (just a regular household iron, must be clean!) we set the temperature of the iron on a three step heating process, starting with a fairly low temperature using a very low cost thermometer calibrator. Lightly move the heated iron over the fabric starting with the center portion of the rudder on one side. Do the same section or quadrant on the other side, the idea being as you shrink the fabric it will start to exert pressure and stress on the rudder frame, and if not careful could distort or damage the structure. So moving from one quadrant to another slowly shrink the fabric on each side until you have both sides completed at the first temperature setting. Next increase the irons temperature by calibration by the required/documented amount and repeat the whole process. The third temperature increase will be the final one and repeat the same process and pattern. With this completed you should see a very nice smooth tight surface with all the wrinkles gone...hopefully. Next as can be seen with closer viewing of the last two photos, you take a pencil and start measuring out the positioning and spacing of where you are planning to start the rib stitching (this is to be determined prior as per the construction manuals)...this is really the fun interesting part...rib stitching!!! ...wait for it...that will be next!!!!
