How to Speed Up Your Work with Spacer Blocks
Little blocks simplify all kinds of joinery
Many woodworkers use stop blocks and fences to make repeat cuts accurately. Alan Turner’s spacer-block techniques take that concept a step further. He shows you lots of ways to use them to move a workpiece exact distances for cutting, boring, mortising, and other tasks. Using spacer blocks, you can move a workpiece closer to, or farther away from, the blade or bit, locking in a final setting on the fence and then taking multiple passes as you remove spacer blocks. Try them, and your mortise-and-tenon joints will be more accurate, your bridle joints will fit their slots perfectly, and your other joinery will fit without fail.
