Quality Control

Quality Control

The Last Defects Are the Hardest to Find

By the time a table reaches final quality control, I have usually been looking at it for months.

At that point, the major issues should already be resolved: flatness, alignment, symmetry, fit, finish, andstructural movement. Those things should be caught throughout the build process.

Final inspection is different.

Now I am looking for the small things: a fine scratch, a slight finish blemish, a piece of dust, a hair trapped in the coating, a tiny bubble buried deep in the epoxy, or a subtle shift that only appears when the light hits the surface at exactly the right angle.

Those are the defects that hide. They are also the ones a client may not notice until weeks or months later, when daylight or room lighting exposes something that was almost invisible in the shop.

My goal is to find those things before the table leaves.

Final Inspection Is a Series of Inspections

I do not believe in one final look. I believe in a series of final inspections.

Different defects reveal themselves under different conditions, so I change the conditions.

Sometimes I use a strong wand light that follows my eyes across the surface. Sometimes I use large overhead lights. I also use a theatrical performance light that lets me control intensity, direction, softness, and color temperature.

I can make the light harsh and direct. I can diffuse it. I can bounce it. I can change the angle. I can move toward a cooler light around 5500 K.

That matters because a defect may disappear under one lighting condition and become obvious under another. A scratch may show itself only under a low raking light. A small bubble may appear only when light passes through the epoxy at a certain angle. A finish flaw may reveal itself under reflected light instead of a direct beam.

The inspection process is really about making the table reveal what normal lighting might hide.

The Big Problems Should Already Be Gone

Quality control does not begin at the end of the build.

By final inspection, I should not be discovering that the table is out of square, badly warped, misaligned, or fundamentally wrong. Those are build-process issues.

Final QC is about refinement. It is about finding the small imperfections that remain after the major work is complete.

That takes patience because the longer I work on a piece, the more familiar it becomes. You begin seeing the table as a whole.

Final inspection forces me to stop doing that. I have to look at the surface again as if I have never seen it before

If I Find It, I Fix It

Once I find a defect, there is not much debate.

If I can fix it, I fix it.

If the problem is on the surface, I remove it and redo the finish. If it is buried in the epoxy, I go after it.

Sometimes that means drilling down to the defect and rebuilding the area. If the problem is larger, I may cut out an entire section and redo it.

That can be tedious and expensive in time, but once I know something is there, I do not like leaving it in the table. I would rather repair it in the shop than know a client may discover something later that I knowingly ignored.

That is especially true with clear epoxy. It has a way of exposing everything. A tiny bubble can disappear under one light and become obvious under another.

Once I see it, I deal with it.

Final Thoughts

The hardest defects to find are usually the smallest ones.

The large problems announce themselves early. The tiny ones hide.

That is why final quality control is less about checking boxes and more about discipline.

Change the light.

Change the angle.

Look again.

Inspect the surface.

Inspect the edge.

Inspect the epoxy.

Inspect the underside.

Then look at it again.

The table does not leave the shop until I am as satisfied with it as I know how to be.

And the truth is, I am rarely completely satisfied. That is not because the work is unfinished. It is because I can always see one more thing to study, question, or improve.

That tension is part of the craft.

Perfection is not something I can promise. What I can do is find peace in knowing I have practiced my craft to the highest level of my ability before the table leaves the shop.
