Pin Chuck

Pin chucks are used by wood turners to hold a work piece internally.  A hole is drilled into a pen barrel, vase, duck call, whistle, etc. then the piece is slid onto the pin chuck to finish turning the outside, my “Bud Vase” is a good example.  The “pin” in the pin chuck shifts off center when the work piece is rotated slightly, locking the piece on the mandrel. The mandrel itself is held in a chuck or collet. In order to remove the work piece, simply rotate it slightly in the opposite direction and slide it off the mandrel. Pin chucks are made to suit internal diameters of your choice. They are fairly easy to make by filing a flat on a piece of round stock but the depth must match the pin diameter so lots of fiddling is required to make this thing work properly. If anyone is interested, I can make a 1/2″ or 5/8″ pin chuck approximately 6″ long for $15.00 plus tax (in Wisconsin) plus shipping.  Use the “Contact” link to order or inquire.
