Masts for Spintronics: When You Need Extra Support

Spintronics masts aren't always needed. This guide helps you diagnose when a mast is missing, broken, or just misplaced, and when to buy a replacement.
Quick answer
You only need extra masts for Spintronics if you're missing one, broke one, or want to keep a build assembled while starting another. Otherwise, the included masts are enough.
Why masts matter in Spintronics
Spintronics uses masts to hold components like gears and springs in place during builds. They're small plastic rods that plug into the board. If one is missing or damaged, your circuit won't stay together properly.
The starter set includes enough masts for most builds, but advanced puzzles or custom creations may require more. Knowing the difference between a missing part and a design choice saves you from buying extras you don't need.
When you might need a replacement
Masts are sturdy but can snap if forced into a tight spot or stepped on. If you notice a mast is cracked or missing, a replacement restores full functionality without buying a whole new set.
If you're building multiple puzzles at once or leaving a creation assembled, you may run short. In that case, extra masts let you expand without disassembling your work.
Diagnosis: Do you need extra masts?
- Symptom: A component won't stay in place, or you see a gap where a mast should be.
- Likely cause: The mast is missing, broken, or being used in another build.
- Corrective action: Check under the board, in the box, or on other builds. If you find a spare, reuse it. If not, order a replacement mast set. A single replacement set covers most gaps.
- When to stop or choose another option: If you only need one mast and have spares from other sets, don't buy extras. If you need more than three, consider buying a dedicated extra mast pack.
