Pappalardo Apprentice Program Redefines Hands-On Engineering at MIT

MIT’s Pappalardo Apprentice Program is upending traditional undergraduate lab experiences by marrying advanced fabrication training with a strong mentorship ethos. Now in its second decade, the program selects juniors and seniors to serve as undergrad lab assistants and peer mentors for the foundational course Design and Manufacturing I (2.007). Apprentices receive specialized training while helping their peers master essential engineering skills.

Daniel Braunstein, senior lecturer in mechanical engineering and director of the Pappalardo Undergraduate Teaching Laboratories, initiated the program to fill a dual need: providing instructional support for large design classes and fulfilling upper-level students’ desires to deepen their hands-on expertise. “It had not occurred to me that we could combine these interests into a manageable and meaningful program,” Braunstein said, reflecting on its origins.

The program’s approach is twofold. Apprentices both support their peers and continue their own technical development through a series of seminars, clinics, and hands-on projects. Training covers a wide range—from advanced mill and lathe work to the intricacies of computer-aided design (CAD) and manufacturing. Junior apprentices build complex devices, such as the Stirling engine—a heat engine converting thermal to mechanical energy—while senior apprentices pursue more ambitious group casting projects. Previous cohorts have reconstructed historical engines now housed at the MIT Museum.

This spring, apprentices are fabricating a copper alloy replica of an 1899 anchor windlass, originally used on the exclusive New York 70 class racing sloops. These vessels, designed by MIT alumnus Nathanael Greene Herreshoff, were icons among affluent yacht club members in the early 20th century. The apprentice team works from archival drawings, navigating both technical and creative challenges. “There is an element of the discovery of what they may or may not have done. It’s like technical archaeology,” Braunstein explained.

In recent years, the casting curriculum has expanded to introduce metallurgy—a field often neglected within traditional mechanical engineering education. Apprentice Jade Durham noted, “It really opened up my eyes to how much material choice is an important thing for engineering in general.” By engaging with historical manufacturing methods, students acquire both context and technique, underscoring the importance of hands-on experimentation in engineering education.

The lab’s unique culture emphasizes collaboration, safety, and creativity. Apprentices build confidence not just in making things, but also in teaching and leading peers. Saechow Yap, an apprentice, said, “I learned a lot about applying my art skills and my ability to judge and shape aesthetic.”

The Pappalardo Lab, sometimes dubbed the “most wicked labs on campus,” is named in honor of benefactor Neil Pappalardo. Its maker ethos blends MIT’s industrial heritage with academic rigor. “MIT has a strong heritage in industrial work; that’s why we were founded,” Braunstein commented. The program aims to “borrow from the language of the trades,” reinforcing the university’s historic ties to the mechanical arts as well as the engineering sciences.

For Braunstein, the true reward lies in witnessing apprentices’ growth—from novice makers to skilled fabricators and mentors, united by a shared passion for solving problems and building community. The spirit of the Pappalardo program is imbued with both tradition and renewal—a space where innovation, legacy, and hands-on skill come together.
