Textbook Excerpt:
Whitney wanted to speed up the making of guns by having machines manufacture each part. All machine-made parts would be alike-for example, one trigger would be identical to another. Identical parts would fit together with all other parts, and gunsmiths would not have to build each gun from scratch. Interchangeable parts would save time and money.
