Dick, I think the main advantage of the whale oil along with many animal oils is the organic acids that react with the metal surface and form an oxice layer that is far more resistant to adhesive wear. This is necessary when the lubrication is non-hydrodynamic, like in heavy loaded gears. Modern high pressure additives have exceeded the performance of these old animal fats, but still function in a similar fashion. There are similar anti-friction and anti-wear additives in modern motor oils. > The > environmental activists caused the demise of that industry - you can't go > out and harpoon your own whales anymore. You could still grow your own whales though, all you need is a large swiming pool. Dick, we know you have the space! D^2
