This simple jig has but one purpose: to help in cutting a glue relief slot in regular lumberyard dowels. To make the jig, simply drill a couple of dowel-sized holes near the end of a beefy scrap of oak. Then crosscut the piece removing about one-fifth of the hole, leaving four-fifths to grip the dowel. Now insert precut dowel pins in the proper-sized hole, and push into the bandsaw to slice a shallow slot.
