Steel Helix: A Gunsmith Machinist's Answer to the Question of the Rifled Barrel 190 pages. 81/2" x 11." Softcover. Dozens of photographs and illustrations. Well-illustrated, comprehensive guide to drilling, reaming and rifling barrels in your own shop. Detailed instructions and illustrations guide the home shop machinist through the process of fabricating a machine capable of turning a solid bar of steel into a finished rifle barrel. A very thorough description of deep-hole drills, reamers and rifling cutter boxes will provide all the know-how necessary to fabricate and heat-treat the cutting tools. The three most common methods of making rifle barrels are discussed, with the pros and cons of each. Four different methods of accurately rotating the rifling cutter box during the cut-rifling operation are examined. There are also separate chapters devoted to selecting the best steel alloys for the job based on chemical composition and mechanical properties and then proof-firing the finished barrel

ORIGINAL SIN Piers Rameau, a brilliant geneticist, was offered the chance to help design mankind's replacement--Original Man, a smarter, stronger, swifter race based on manipulated human DNA. But Rameau refused, and chose to follow his own path. Now Kuno Gunnarsson, creator of Original Man and Rameau's would-be employer, is dead--but his superior creation lives on. And one faction of Original Man is determined to wrest control of the galaxy from the inferior race. A brutal attack destroys both Rameau's home planet and the satellite that has become his world. One tragic casualty is Dakini, a fragile, genetically altered dancer who had become Rameau's reason to live. The sole survivor, he finds himself a prisoner of Gunnarsson Prime, a clone of the original creator, on board the Jumpship Langstaff. Against his will, Rameau is enlisted as the ship's wartime medical officer. As a doctor, he swore an oath to do no harm. As a man, he swears blood vengeance on the inhuman killers who destroyed everything he ever loved . . . .
