Hurricane Standard Series Pen Mandrel Saver. This a great upgrade to the standard pen mandrel system. Excessive pressure from the lathe tailstock on the pen mandrel can cause it to bend, making your pen blanks "wobble" or be "out of round".
Features:

Used in tailstocks to secure pen blanks on the mandrel

Eliminates damaged mandrels and out-of-round pen blanks by putting pressure directly on the pen bushing, not the mandrel

Adapts to almost every mandrel with a shaft diameter of .245" (6.22mm) or smaller; mostly commonly used with 7mm mandrels

Tailstock Mount: #2 MT (Morse Taper)

Material: Steel
