To make sure the fences on my biscuit joiner and Domino end up parallel to the base, at precise heights, I use a set of simple spacer blocks that I made with common woodworking tools from acrylic plastic. Some of my blocks are designed to center biscuits and Dominoes in common wood thicknesses. For the Domino joiner, which has a metric scale for fence height, the blocks also convert the tool to standard measurements.
