An extra index plate for the Joyner Off-Set Jig is very handy as you can keep a solid waste block on one to turn pendants and box lids. Keep the bolt with a waste block on another to turn bottle stoppers, box knobs or fun stuff. It comes with a 3/8″ x 16 tpi bolt and 4 wood screws; which are not necessary when you use the bolt as it will tighten the waste block.
