Workshop tip: Acrylic spacer blocks to set joinery machines
These acrylic blocks help center biscuits and Dominoes in common wood thicknesses.
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.
