IASCOTT wrote:Back in the day airplane were covered in linen or grade A cotton. The fabric was glued to the frame using nitrate dopes. Then the fabric was dampened with water to start the initial shrinking. Then the fabric was treated with a fungicide. Then clear shrinking butyrate dope is sprayed or brushed on to continue the shrinking of the fabric. Once desired tautness is gotten which is usually 3 to 4 coats which fills and seals the weave. Then you switch over to non tautening butyrate dope which you mix in silver powder this is you UV protection. It takes 2 to 4 sprayed coat to achieve a no light penetration on the fabric. Then you go to spraying colored butyrate dope for the final finish.

some of the fishing shanties on lake erie are tubing and covered with fabric like airplanes

having covered many airplanes using dacron or any covering after applying the dope you would be surprised how much weight is added by the dope,
that's the covering dope not the dope doing the covering :lol:

There was another book like Rolling Homes called Afghani Trucks. I saw it once in a used bookstore years ago and regret that I didn't buy it on the spot. I was about big cargo trucks, painted with ornate, colorful patterns everywhere, tarps over really tall loads of goods and foodstuffs and spaces in front of the loads for the family to travel and sleep. That was from the early 70s before the Russians invaded. If I recall correctly, many of the photos were of those trucks negotiating the Khyber Pass.
