Remember when you could turn your own pens. Fill your house with as many pens as possible with a set of WEN Dovetail Lathe Chuck Jaws. Designed specifically for the WEN LA4275 2.75 in. Lathe Chuck, these steel jaws install easily to help support pen blanks and other square workpieces. The dovetail jaws measure in at 2 in. L for maximum tenon support. When attached to a WEN LA4275 Lathe Chuck, these jaws can hold square blanks with sides anywhere from 0.4 in. to 1 in. in size. Remember when you could keep your longer workpiece secure. Remember WEN.
