Woodworking Troubleshooting: Find the Cause Before the Fix
Start with the failure you can see, then work through a short diagnostic sequence before changing dimensions or consuming more material. These pages connect problem-shaped searches to measurable checks, safe stop conditions, and the exact WoodCutTool resource needed for the next decision.
How to use this library
Search by symptom, not by the fix you hope will work
Choose the page whose observed condition matches the project. Preserve the current list, layout, or setup; run the checks in order; and change one variable at a time. A specific diagnosis produces a defensible next action. A guessed fix can move the same error into assembly, finishing, installation, or the material order.

Diagnose the problem →Why troubleshooting deserves its own column
Learn guides explain a complete method, templates help define a project, and cut list examples publish finished inputs and layouts. Troubleshooting pages begin later: something no longer fits, matches, cuts, or reconciles. Their job is to help a reader isolate the cause and return to the correct tool or source document.
That distinction also keeps search intent clear. A reader asking “why did my optimizer add a sheet?” needs a threshold test before a general optimization lesson. A reader asking “why are my drawer fronts uneven?” needs to separate case, hardware, box, and front errors before another dimension is cut.
