PSI Seam Ripper Bushing Set

Bushings are a gauge indicating the recommended final diameter of the finished pen or project blanks. To use, simply mount the blanks between the bushings (following the kit instructions) onto a 7mm pen mandrel. Turn the blanks down to match the bushing diameter, leaving a little extra material for final sanding and finishing.
