Why MDF is a versatile and inexpensive building material
By Steve Maxwell
MDF works well for making jig parts that aren't under a lot of stress, especially jig bases. This material can be drilled and tapped to accept bolts, which is useful for knock-down jig assemblies. Predrill correct-sized holes for coarse-threaded bolts from 1/4"- to 1/2"-diameter; use a drill to run a metalworking tap into and out of the hole. Use a countersink bit to remove frazzled fibres at the top of the hole, then install your bolt.
