    I’ve learned so many things from this podcast. I started as an operator in January. I setup, run first part, then run the production. We are a 2 person shop

Talking Points

Recent interactions between the hosts and their guests.

Within Tolerance Episode 286 - The Post IMTS Plague with Zap
Q: When should a shop go head-on into full automated five-axis versus stepping-stone it?
The hosts generally recommend getting processes and five-axis work dialed in before relying on automation, while noting that buying an automated system first can make sense if the budget and system support it. Automation can expose process gaps and bring new demands for tooling, workholding, chip handling, and coolant management.
Within Tolerance Episode 286 - The Post IMTS Plague with Zap
Q: As someone who is new to horizontals, is center rotation or general work offsets better? We do a lot of high-precision prototyping. I've tried both, but center of rotation can get more difficult and time-consuming for second operations.
Chris favors center-of-rotation programming because probing and macro-controlled offsets make it easier to use a consistent setup across pallets and fixtures. Second operations can be more complicated, but probing can account for the differences.
Within Tolerance Episode 285 - Chris Townsend of Eagle Manufacturing
Q: How do you evaluate students when turnover is high and shifts are short?
We focus on employability skills, weekly participation, and reflective assessments; students document daily work, attendance, and problem-solving; seniors and managers help with interviews and placement decisions.
Within Tolerance Episode 276 - Joseph Alonso of Novo Modo
Q: How did you find customers when you started Novo Modo?
I launched with almost no customers and relied on a strong network and advocacy from early partners; I also built credibility by delivering high-precision parts with a lean, repeatable process, and then used that proof to win more business.
Within Tolerance Episode 272 - Ethan Perrin
Q: How do you balance your work and personal projects?
Ethan highlights the flexibility of his role at Tesla, allowing him to manage time effectively between work commitments and personal projects in the makerspace.
