Large Scale Line Boring and Family Business

Rottler Manufacturing: The Unsung Hero of Combustion Engines (100 Years of Made In America)
What happens here
The tour continues to the largest machines, used for line boring engine blocks. The host explains the challenge of line boring, where standard tooling does not fit into an engine block to allow for precise alignment. Rottler developed a unique right-angle drive system for its machines, which repeats alignment within one ten-thousandth of an inch. This innovation allows for the repair of large engine blocks that would otherwise be discarded due to wear or torsional fatigue. Andy Rottler's daughter, Corrine, who also works at the factory, is introduced, highlighting the company's multi-generational family involvement.
Goal: Demonstrate advanced line boring technology and highlight the family business aspect
Tools and materials
- Line Boring Machine — Precisely boring engine blocks
