Uneven shank depth: depending upon the shank design, it’s dimension from top to bottom should remain consistent around the bottom.
Uneven shank width-shank width on one side has been over-filled.
Resizing location incorrect-sizing should be done at the bottom unless there are quality marks or an inscription that precludes it.
Visible solder seam-visible solder seams are a sure sign of improper soldering and potential breakage. The solder must be redone to correct the issue.
Cold Solder joint-solder seams which have solder covering the exterior portion of the shank and not the entire width or depth of the shank. While most undetectable, this seam will break open through normal wear and must be resoldered properly.
Incomplete solder seam-incomplete solder seams result from uneven heating during the resoldering process.
Visible tool marks-visible tool marks such as lines, dents, and poor finish on the ring are a sure sign of poor workmanship.
Overlapping and filled with solder-this error is caused by poor shank realignment during the shank reforming and soldering process. Filled with solder to cover errors in workmanship.
