Mr. Puzzle: Assembly of a TECHING Miniature FULL METAL Turbofan Engine

Mr. Puzzle:

Welcome back, DIY enthusiasts!

Today, we’re diving into one of the most spectacular assembly kits we’ve ever encountered—TECHING Turbofan Engine DM119.

When the massive box containing TECHING DM119 Turbofan Engine Kit arrived, I knew I was in for something special. This wasn't just another model - it was a 1,000+ piece mechanical masterpiece that promised to test both my patience and engineering skills.

Why Is It Special?

1. Estimated Assembly Time: 10+ hours (no joke—this is a marathon, not a sprint).
2. Number of Parts: Over 1,000, mostly metal (yes, metal—not plastic).
3. Difficulty Rating: 5/5 (Tishing’s highest tier—expect a challenge).
4. Weight: A hefty 5–7 kg (this isn’t just a model; it’s a statement piece).
5. Instructions: 120+ pages of detailed, step-by-step guidance (thank goodness for diagrams).

The kit arrives in a massive box (barely fit on my screen), and even the instruction manual feels like a textbook. But trust me—every page is worth it.

Assembly: Where Patience Meets Precision

Over 10 intense hours, Mr.Puzzle:

1️⃣ Built the dual-spool compressor system (mimicking real jet engine physics)
2️⃣ Assembled the combustion chamber section
3️⃣ Installed the high/low-pressure turbine arrays
4️⃣ Completed the aerodynamic outer ducting

Pro Tip: 1920s-inspired Medmo Pocket Driver was invaluable for tiny screws. Its unique ratcheting mechanism (listen to that satisfying click!) made adjusting micro-components a breeze.

Engineering in Miniature: How It Works

This isn't just a display piece - it's a functioning turbofan model:
✔ Front fan draws in air (only 20% enters the core)
✔ Compressor stages increase air pressure step-by-step
✔ "Combustion" simulated via electric motor
✔ Turbines convert energy to spin the fan via central shaft

The attention to detail is staggering - even the bypass airflow that reduces engine noise is accurately replicated.

The Moment of Truth: Startup!

After some final tuning (too tight = no spin!), I connected it to a power bank. The result? A smoothly spinning turbofan that looks and behaves like the real thing!

Final Thoughts: Worth Every Second

This kit isn’t just a puzzle—it’s a tribute to engineering. The attention to detail, the heft of the metal parts, and the satisfaction of seeing it run make it a must-have for hobbyists and collectors alike.
