I'm thinking someone on this forum might know. I'm considering building a replica of Octave Chanute's 1896 glider. So I'm testing coatings on frames of light cotton muslin. Chanute used "pyroxylene" and I have his formula -- and it's an outright Explosive! The modern egual would be nitro-cellulose dope (it must shrink and tighten the fabric). Well I wanted to avoid the nitro-cellulose and I purchased the minimal amount of butyrate "tauntening" dope. I've discovered that this stuff doesn't actually taunten any fabric I've tried. The coated fabric ends up more slack than before it was applied. This is Randolph Products 9701 "tauntening" butyrate dope.
Can anyone explain the "tauntening" label on this product? What am I missing?
