Engineering Manager’s Guide: Onboarding Teams to Handle Stuck Penny Tubes with Precision

Want your team to master a tricky task fast? It starts with smart onboarding. I’ve built training programs that get teams up to speed quickly and confidently. Here’s how to do it for one of the most unusual challenges you’ll face: freeing coins from decades-old penny tubes that refuse to budge.

Introduction: The Challenge of Stuck Penny Tubes

Picture this: Your team gets a batch of old penny tubes. These aren’t store-bought rolls. They’re vintage, with plastic that’s warped and shrunk over time, gripping the coins like a vise. As an engineering manager or trainer, your job is to equip your people to handle these stubborn tubes—quickly, safely, and without wrecking the coins inside.

This guide walks you through an onboarding plan designed for real-world results. We’ll cover how to assess skills, create clear instructions, run practical training, and track progress—all tailored to mastering penny tube extraction with care and precision.

Step 1: Team Onboarding and Initial Assessment

Start strong. A solid onboarding process sets the tone. It gives everyone a shared understanding of the project, the materials, and how to stay safe.

1.1 Define Clear Objectives and Expectations

Clarity drives focus. What’s the mission? Maybe it’s to extract every coin undamaged, preserving their historical value. Or it’s to minimize time per tube. When goals are specific, the team knows what success looks like and can measure their progress.

1.2 Conduct a Skill Gap Analysis

Not everyone knows how to free a jammed penny tube. That’s okay. Start by checking what your team already knows. Have they worked with heat? Mechanical tools? Chemical solvents?

Look for gaps. If no one’s used thermal methods, schedule a session on the coefficient of thermal expansion (CTE)—how materials expand when heated. It’s key to safely loosening plastic without cracking coins.

Use a simple template to map it out:

• Skill Area: Thermal Expansion Techniques
• Current Proficiency: Low
• Training Needed: Workshop on CTE, hands-on with hair dryers and boiling water
• Expected Outcome: Team can safely apply heat to free tubes

Step 2: Creating Comprehensive Documentation

Good documentation saves time, cuts mistakes, and helps new hires get up to speed fast. Think of it as your team’s playbook for stuck penny tube extraction.

2.1 Standard Operating Procedures (SOPs)

Write clear SOPs for each method:

• Thermal Method: How to heat tubes with a hair dryer or boiling water. Include temps, timing, and safety steps—like using tongs and avoiding steam burns.
• Mechanical Method: How to cut tubes safely with a pipe cutter or saw. Specify blade types, cutting depth, and how to handle sharp edges.
• Chemical Method: How to soak tubes in acetone. List soak times, container types, and safety gear like gloves and goggles.

2.2 Visual Aids and Diagrams

Words aren’t always enough. Add annotated diagrams showing the right way to position a tube for cutting or the ideal water level for boiling. Visuals help everyone, especially those who learn by seeing.

2.3 Troubleshooting Guides

Expect problems. What if a coin won’t budge after cutting? Suggest reheating or gently prying with a screwdriver. Add a flowchart to help the team decide next steps—no guesswork needed.

Step 3: Internal Workshops and Hands-On Training

Reading about a technique is one thing. Doing it is another. Workshops let your team practice under guidance, building confidence and muscle memory.

3.1 Workshop 1: Thermal Expansion Techniques

Get hands on with heat. Provide:

• Hair dryers and heat guns
• Boiling water setups
• Oven mitts and tongs

Let the team test different heat levels and times. They might find a gentle boil works better than a rolling one—less risk of water getting inside the tube.

3.2 Workshop 2: Mechanical Extraction

Set up a station with pipe cutters, hacksaws, and pliers. Use scrap or low-value tubes for practice. Focus on precision—cutting too deep can nick coins. The goal? A smooth, repeatable process.

3.3 Workshop 3: Chemical Solutions

For acetone, create a safe workspace with ventilation and protective gear. Have the team check tubes daily and log changes. This teaches patience and sharpens observation skills—critical when working with delicate materials.

Step 4: Measuring Team Performance and Productivity

How do you know if the training works? Track results. Use clear metrics that reflect real progress.

4.1 Key Metrics to Track

• Extraction Time: How long it takes to free all coins. Lower times mean faster workflows.
• Coin Damage Rate: How many coins get scratched or dented. Aim for under 5%.
• Method Efficiency: Which method works best? Heat, cut, or chemical? Compare success rates to guide future choices.

4.2 Feedback Loops

After each workshop, listen. Send a quick survey or chat one-on-one. Ask:

• Which method felt most reliable?
• Did anyone feel unsafe?
• What would make the process better?

Feedback keeps training relevant and responsive.

Step 5: Advanced Techniques and Innovation

Once the basics are solid, push further. Introduce techniques that solve tougher cases and spark creativity.

5.1 Vacuum and Air Pressure

Show the team how air pressure can force coins out. It means drilling a tiny hole and using a pump. It’s not always the first choice, but it’s a powerful tool for the most stubborn tubes.

5.2 Freeze-Thaw Cycles

Some say freezing doesn’t work. But alternating between cold and heat? That can stress the plastic and crack it loose. Teach the team how freeze-thaw cycles work—and when to try them.

5.3 Custom Tools

Let the team invent. Maybe they’ll design a tube holder or a heating jig. Encourage tinkering. Ownership boosts engagement—and often leads to breakthrough ideas.

Step 6: Continuous Improvement and Documentation Updates

Great training never stops. Keep learning, keep refining.

6.1 Monthly Review Sessions

Once a month, meet and talk. What’s been hard? What’s working? Update your SOPs and troubleshooting guides with new tips. If a new plastic type (like Meghrig) needs a different approach, document it fast.

6.2 Knowledge Sharing

Set up a shared space—a wiki, drive, or folder. Let the team upload photos, videos, and notes. That way, no one repeats a mistake, and everyone benefits from shared experience.

Conclusion: Building a High-Performance Team

Training a team to free stuck penny tubes isn’t just about technique. It’s about building a group that learns, adapts, and improves together. With this approach, your team will:

• Know the project goals and their role
• Have clear, easy-to-follow instructions
• Build skills through hands-on practice
• See their progress with real metrics
• Keep getting better through feedback and innovation

The methods matter. But the real win? Creating a culture where people feel confident, supported, and ready for any challenge—penny tubes or otherwise.
