Illustrated description of steps employed in fabrication of one-piece aircraft propeller blades from steel tubing; blade starts as 8-ft length of chromium nickel molybdenum steel tubing 9 in. in diam, weighing 300 lb; after machining, forming, welding, trimming and grinding, weight has been reduced to less than 100 lb; it has considerably more strength as well as resistance to abrasion and impact than equivalent forged aluminum propeller.
