Troubleshoot a Specific Craft Problem Step by Step

Something keeps going wrong and you cannot tell if it is the tools, the technique or you. Describe the problem, your kit and your skill level. This names the most likely cause, lists the alternatives in order, and gives you the steps to fix it. Less trawling forums for a half-answer, more actually solving it.

**Explain** the likely root causes of this problem and how to fix it:
1. Diagnose the most probable cause based on the description
2. List alternative causes in order of likelihood
3. Provide a step-by-step corrective process for the most likely cause
4. Suggest a test to confirm the fix worked
