Episode notes
From Chef To Precision Machinist
- Drew Hash transitioned from a 25-year chef career into knife making before becoming an apprentice machinist at Lawrence Livermore.
- His cooking and blade-making taught patience, timing, and attention to tiny adjustments that translated to high-precision machining.
Old Machines Still Lead In Accuracy
- Machinists at the lab blend old and new tools, from manual lathes to computer-controlled systems, to produce mission-critical parts.
- Some machines decades old, like the 1953 Swiss Jigbor, still outperform many modern tools in accuracy.
Solve Problems Your Way
- Use creative processes to meet print requirements as long as the end goal matches specifications.
- Embrace troubleshooting and independent thinking to find multiple valid ways to fabricate a part.
