Re: [BKARTS] glue



Kathy,

The dope used for sealing the tissue of light-weight, free-flight airplanes was a nitrate dope ...the same as used to cover the fabric of the early, full-sized airplanes, except it was greatly thinned out for model making. The fumes from nitrate dope are very heady and were often applied by young builders in unventilated bedrooms and basement workshops, making them dopey. Yes, it is the origin of our current use of the word dope. You know, they'd be flying on the stuff, the dopes.

Collodion, Jack, was used with nitrate dope to seal the fabric covering of dirigibles. It offered a better seal for the gases contained in the structure.

I did not know that. My godfather built model airplanes that flew by remote control and they painted a liquid on it that stabilized the tissue. I think it's called dope (no connection to drugs).
