Hand-Cut and Machine-Cut Dovetails: Identification Guide

Hand-cut dovetails often show layout variation, saw marks and pared baselines, while machine-cut joints can be more regular. Early machinery, specialised workshop jigs and skilled hand production create exceptions. Examine both drawer corners, pins and tails, scribe lines, kerfs and tool access. Repairs and replacement drawers complicate interpretation. Dovetails should be combined with drawer bottoms, hardware, timber and overall construction.

Examine without damage

Use good light, magnification and existing end grain or protected surfaces. Do not cut, scrape, wet or sand original material merely to obtain a test area.

Compare several components

Show wood, secondary wood, veneer, drawer linings and later repairs may differ. Record where each observation was made and whether finish or stain changes appearance.

Combine evidence

Joinery, tool marks, hardware, design, provenance and documented comparables should support material identification. One grain pattern or fixing is rarely decisive.

Common traps

Colour changes with age, coating and photography. Old timber can be reused, new hardware can be added during repair, and revival furniture may imitate earlier methods.

Responsible conclusions

State confidence and limits. Botanical species, exact dates and protected timbers may require microscopy, laboratory analysis, documentary evidence or regulatory advice.
