A brushed aluminium cutaway lock for configurable practice
This Dangerfield Aerospace practice lock is a solid metal cutaway trainer with pins and tweezers included. It is made for pickers who want a tougher, cleaner-feeling trainer than acrylic and a lock they can reconfigure as their skill grows.

Buy this when you want a metal trainer with room to grow
Acrylic is brilliant for first sight-based learning. A brushed aluminium repinnable lock is the next step: still visible, but more substantial in the hand and more flexible as a training platform.
Metal feedback
A solid body gives a firmer bench feel than lightweight clear trainers.
Rebuild the lesson
Use the included pins and tweezers to change the lock as your practice develops.
Cutaway diagnosis
See what is happening, correct the error, then repeat by feel.

How to progress with it
Set an easy pinning first and learn the lock. Then add one variable at a time: another chamber, a harder pin, or a lighter tension target. That keeps the feedback useful instead of chaotic.
- Start simple before loading every chamber.
- Use the cutaway view to find oversetting and heavy tension.
- Keep pins organised in a tray while reconfiguring.

Quick answers
Why choose aluminium?
It feels more substantial than acrylic while still giving the visual help of a cutaway trainer.
Is it beginner friendly?
Yes, if you start with a simple pinning and add difficulty slowly.
What makes it different from a fixed trainer?
You can repin it, so the same lock can teach more than one lesson.
What should I add?
A pinning tray keeps springs, pins, and experiments under control.
Give your practice bench a reconfigurable metal lock
The Aerospace trainer is built for pickers who want visibility, weight, and the freedom to change the challenge.
