"What'i a rNoiDUNC pin?" was the question. If you readers remember. Mermadukc Surfaceblow sounded off about the 2004b knlbbling pin that Chief Engineer Crogan took ashore In Shanghai, Jenoiry Powsn. Ever since, letters hove been flooding us. Everyone wants to know what part of tho engine that pin is In, or what It does. So yesterday we decided to find out. I headed over near the waterfront to Marmy's dingy office above O'Houliban's Machine Shop A Engine Works. Climbing the creaky stairs to the sec* ond floor, I stopped in front of the door with the bright red sign reading Marmaduke Surfacebloic, Erg, CentalUng Engineer. The door was ojer. Tobacco smoke coming from inside told me not only that Marmy was in, but also that he had a full head of stoom tip on his boiler. Inside, the lough old sea horse was firmly anchored with his stern in the battered .swivel chair and his long legs propped up on his roll-top desk. He reminded me of the bowsprit poking oheod of an old square rigger. A large blueprint lay on his slightly bulging midship section. Mtrmy, who had been through so many sea and land cam* pslgns, was studying the print intently through a cloud of smoke, as if charting a course for some tropical island. "Here's s stack of mail about that story in the January issue," I said cheer* fully, dumping it on his desk. `Tour public wants to know wits; a kktobuxc pift Is." "BlLCKWATRn ON KN1BBLINC PINS." roared Marmy, shoving the blueprint to one side and glaring at hfs mail. "I'll tell you about a tough hydraulic pack* ing problem that wo# solved by com* mon, everyday horse sense." I grabbed a chair. Mermy blasted sway. "Back In 192B, 1 was a millwright for a large rubber company in Akron, Ohio," roared Marmy, like a hungry Hon. "We hod a string of ISOO-psi hy draulic presses.
