Another member on another thread mentioned these on eBay. I'm wondering what they are used for?
My guess would be that you place them on the pins on the indexing fence on the Domino 500 to move the mortise closer from the edge of a piece depending on the size of the spacer. Any thoughts on this? Domino 500's are sold now with paddles instead of pins which would make them useless on the new style fence. Just curious.
