Pietenpol-List: fabric shrinking temp.

The system I used must be shrunk at exactly 400 deg. or in time or on cool days the fabric relaxes (memory in the fibre) and you then have to wait untill the sun warms up the surface thereby temporarily shrinking it. this has happened to a friend of mine who used an regular iron that could only reach 385 deg. After 10 years he is now recovering. I took a regular iron apart to get to the calibration screw, placed it on a wad of fiberglass and a thermocouple and adjusted the temp. untill it stablized to 399.9 deg. This can be done for whatever temp. you need. Oh yes, don't use a candy thermometer to calibrate, they are not accurate. The one I had previously used was 100 deg. higher than the reading showed. Consequently I already have my first repair on the Piet. and it hasn't flown yet.Regards to all,Domenic________________________________________________________________________________
