[Healeys] 100 Draft tube

[healeyguy at aol.com]

Listers I attempted to add a 7 second video of a demonstration of how a draft tube works but it was rejected on the list.  Probably file size.  Anyway wanted to show the effectiveness of a draft tube in operation. Had my shop fan blowing parallel with the floor (car in motion), a empty paper towel tube and a strip of Kleenex tissue.  Cut one end of the tube at an angle, about 30 degrees. Held the tissue paper over the upper square end of the tube and slowly lowered the angle cut end vertically  into the fan wash, Only had to lower the tube less that 2 inches  and the tissue was sucked down the tube.  The engineers way back when knew what they were doing with regard to ventilating the engine in a very simple but not very environmental way. As Mr Dylan once said. "Ah, but I was so much older then, I'm younger than that now..."  :)P
