Drill dead-on dowel joints
Problem: I set the jig up correctly, but the, dowels still fit sloppily in the drilled holes.
Solution: Check that the dowels have been made to precisely the rigtht diameter (below right). Mass-produced, commercially available dowels may be manufactured slightly over or undersized, and, like most wood, swell or shrink with humidity change. If the dowel size matches, it may be that your jig's guide holes have become worn and imprecise -- leading to sloppy dowel holes. Replace any guide hole inserts, or, if the jig doesn't have them, discard the jig.
