This educational app provides a detailed look at the 1853 Robins & Lawrence Rifling Machine using real-time 3D.

The 1853 Robins and Lawrence Rifling Machine App is compatible with the New iPad and the iPad 2. Due to the extremely high-resolution models and textures, this app is not compatible with the first generation iPad.

Two of the most important innovations in the manufacture of weapons during the Civil War were the addition of rifling to the inside of handgun and rifle barrels, and the ability to mass-produce those barrels for the Union Army. In 1853 Robbins & Lawrence manufactured a rifling machine that helped produce more than 1.5 million rifled barrels by the end of the Civil War.

Although the rifling machine is historically interesting, the focus of the app is on the key mechanical elements that allow the machine to quickly and accurately cut the rifling on the inside of each barrel. The machine itself is animated to illustrate the interaction of all of the components during operation.

• The 3D app allows the user to pan and zoom interactively to explore the machine from almost any angle or position.

• A menu allows the user to select from a list of key mechanical components, while additional information explains their specific functions.

• Additional navigation features allow the user to proceed through each of the key mechanical components one at a time.

Very nice

I agree. More early machine models would be great. This was a very nice informative app. Well done, and my kids enjoyed being able to see how it worked.

OMGosh this is Amazing

I realize this free model must have been created as an advertisement for the two company's capabilities but I would love to see more industrial age mechanical models.

Wonderful App!

This is a great learning tool. As a mechanical engineer, I would love to see more machines explained like this! If the developer would like any 3d modeling help, let me know!!!
