Leather canon barrels
This was is not a dream of a mad person, but once it was a highly demanded product. I see no special reason for making jokes about the Tibetan cannons shown. Skin is a natural composite and has high strength, with low weight.
The barrel is formed by winding a sufficient number of layers of raw skin onto the mandrel, after drying it, forms a strong structure capable of withstanding the shot not only by stone grape shot but also by the core. Naturally, the mass of the charge is much lower than for a metal barrel, but it is sufficient to give the projectile a speed that provides a killer effect.
With a lower weight of the trunk made of leather, it has sufficient strength, and weight during the war in the mountains is crucial, plus the availability of raw materials for this kind of guns. Of course, the so-called leather cannons of Europe, had a thin-walled liner inside, and fired cores almost on par with all-metal guns. Weight charge was lower than usual by 30%. Tibetan guns without a liner had a charge even smaller, but giving sufficient combat effectiveness, in favor of which testifies the very fact of the presence of such guns.
The barrel formed by multilayer winding is not made of durable leather, but simply of paper, has been used successfully for the manufacture of pyrotechnic mortars now. Back in the PMV, the British used steel trunks WRAPPED, FOR THE STRENGTH OF A SQUARE SECTION WIRE.
In hydraulics, in order to increase the strength of hydraulic cylinders (1960-1970GG-USSR), the winding was done with a tape, which allowed very high pressure, with a minimum weight. So, any irony about using winding for making canon barrels is inappropriate
