Mini-Pro Rub Spacer, 1/4″ x 3/8″ Tongue

This rub spacer fits the Mini-Pro M-50/P-10 series on the 3/4″ bore spindle and is sized for the 1/4″ x 3/8″ tongue profile — the shallower of the two imperial tongue depths in the Freeborn Mini-Pro range. The shorter tongue depth suits lighter cabinet frames and stile profiles where less tongue engagement is specified. Swapping the center cutter for this spacer on the cope pass keeps the spindle stack at the correct height, so the fence and collar settings established on the pattern side carry directly across without adjustment. The cope cut mirrors the pattern geometry, and the joint tightness that results reflects Freeborn’s machined tolerance rather than a shimmed approximation. Stock alongside AM-50-801 to cover both standard tongue depths in the M-50/P-10 system.
