Axminster Pin Chuck

The pin chuck is a simple device which relies on the cam action of a pin rolling on a flat machined on the shaft to provide a secure grip for the workpiece. All that is required is a 25mm hole bored in the end of the timber; this is then slid onto the pin chuck with the pin in position on the flat and when the timber is rotated slightly the pin jams between the flat and the timber and locks it firmly in position on the chuck. The 5/8" diameter mounting shaft will fit in the nose of the accessory mounting jaws of the Super Precision, Woodturner's or Clubman K10 chucks.
