Not so many years before that, in England, James Watt was complaining about the difficulty of boring a six-inch cylinder for his steam engine with sufficient accuracy to make it a commercial success. No matter how he packed the piston with cork, oiled rags and old hats, the irregularities in the cylinder let the steam escape, and it was believed that neither the tools nor the workmen existed for making a steam engine with sufficient precision. When a young manufacturer named Wilkinson invented a guide for the boring tool, and machined cylinders of fifty inches diameter so accurately that, as Watt testified, they did not err the thickness of an old shilling in any part, it seemed as though the last refinement in machinery had been achieved. That was not very accurate by present-day standards of the thousandth part of an inch, for a shilling is about one-sixteenth of an inch in thickness.

Remington was right in the thick of development with a gunmaking plant, of course, for as his business grew he had to invent and adapt machines to increase output. The lap-welded barrel was standard until 1850, and he got together a battery of trip hammers for forging and welding his barrels. Finer dimensions became a factor in his business when the output grew large enough to warrant carrying a stock of spare parts for his customers, and so he improved those parts in ways that gave at least the beginnings of interchangeability.

Materials were very crude. There was no buying of foundry iron by analysis, no high carbon steels, no fancy tool steels - nor any "efficiency experts" with their stop watches and scientific speed-and-feed tables. Iron was secured by sending teams around the neighborhood to pick up scrap, and when the scrap iron was all cleaned up, fresh metal was brought from ore beds in Oneida County. Coal was scarce, and charcoal made the chief fuel, burnt in the hills round about Ilion.

And the world was fairly swarming with inventors !

That was long before invention became a research department full of engineers. The individual inventor, with a queer-shaped factory process, carried on by a head and a rough model in his carpet-bag, had a chance to influence industry. Few of the useful contrivances had been invented yet, and almost any one of these chaps might be a genius. So, from the very first, Remington was interested in inventors. He was an inventor himself! His pioneer spirit was so strong that Ilion became a place of pilgrimage for men with ideas. Inventors came from everywhere, and Remington listened to them all. Some brought models, others drawings, still others a bare idea, and a few, of course, had just a plain "bug."
