Fabric tightness

Posted: Monday, September 1, 2014 4:09 PM Quote
I am using the Superflight 102 recommended by Stewart System.
I have previously used Ceconite 102 with the Dope systems.

The tension I get with the Superflight and Stewart System is less than I got with the old Dope System.
I have my iron calibrated and using the point infrared temp gauge. I have also read the comments regarding the old and new Ceconite weights on your web site.

The fabric feels nice and tight before I start painting but then seems to dull off after painting. It is not "twangy" tight.
I complete the ironing with it set at 350deg.

Does this make sense please Jason?

Maybe my question was too open ended?
I have since checked my iron calibration with the little coil type thermometer and the two types are within about 20 degrees of each other.

How can I test my finished fabric for correct tension?

there is no tension test which is why using an iron at the proper temp is so important.  Fabric may be a PMA'ed part but it changes from time to time based on the manufactures and as long as it meets the pull test required by the FAA it's approved. How taught the fabric is is not one of the test.
