Tremont Nail Manufactures an Old-Fashioned Product With an Up-to-Date CINCINNATI Shear
 |
Tremont Nail, the oldest nail mill in America, still manufactures old-fashioned cut nails, the type it has been producing for more than 180 years. Its main mill, well more than 150 years old, is designated as a national historic landmark.
Not everything about the Wareham, Massachusetts manufacturer is old-fashioned. Tremont Nail cuts metal with a new CINCINNATI 1806RG mechanical shear. And what's more, plant engineer Mike Pranic is using it in a doubly efficient manner. "Everybody told me it was impossible to shear two sheets of steel at a time," Pranic said. "I have been told nobody has done this, but we are doing it very successfully." Pranic perceived quickly that shearing two sheets of steel at once could be done. "The stops come down and hold the piece," he said, "and if the holddown is good, you can do it. I thought, if you can shear one piece, you can shear two. Nothing is impossible-some things are just a little bit harder to do than the others."
Indeed, in all metalworking operations, accuracy depends greatly on how firmly the work is held during the cut. Solid clamping by powerful holddowns is one of the prime reasons for the micrometer accuracy of CINCINNATI shears. A heavy, uniform pressure is applied along the full length of the workpiece, minimizing slippage regardless of variations in thickness.

Shearing Two At A Time
Plates of steel emerge from Tremont's mill in bundles of about 10,000 pounds. Plates are put on rollers two at a time, where they go through a continuous abrasive cleaning and lime-coating process. Suction cups then pick up the plates and drop them onto a conveyor which carries them to the shear. Sheets measuring about 108 inches by 24 inches are inserted into the shear side by side. "We shear several million pounds of steel nails a year," Pranic said. |

World's Largest Variety
Tremont, a unit of the W.H. Maze Co., based in Peru, Illinois, makes 20 patterns of authentic cut nails-the widest variety of cut nails in the world. Tremont's cut-masonry and cut-flooring nails are in demand worldwide because of their excellent drivability and reputation for quality. "We manufacture old-fashioned cut nails-up to eight inches long-made out of plate, not wire," Pranic said. "They are used a lot in restoration projects and in hurricane zones, where they are fastened in concrete to meet local building codes. They have much better holding power than a wire nail." |

Comparison Shopping
Pranic said he exhaustively researched every shear maker before deciding to buy a CINCINNATI. "I investigated every shear manufacturer on this continent," he said. "I knew about CINCINNATI, but not directly. So I gathered materials from each company and compared them all."
One of the deciding factors was reliability, the hallmark of CINCINNATI machines throughout the company's long history. "That's very important in my book," Pranic said. |
