Step 3: Build the Jig Body
The jig body is fairly straight forward and easy to make. The goal is to end up with a U shape that has a sturdy length that serves as a backstop and two arms for attaching your dowel and flip stops (see next step). A set of runners holds the jig in place on the drill press.
Notes for the backstop:
-Make sure your back stop is square! Use a jointer and planer if it isn't.
-Make sure your back stop isn't too high - it may stop the drill from being able to fully lower. Mine was originally an inch or so too tall, so I ripped it on the table saw to cut it down to a better size.
Notes for the arms:
-I used a piece of scrap to test out several drill bits until I found one that made holes that fit my dowel snugly. Then I drilled two holes in each arm (this will allow for raising the dowel to a higher height to accommodate odd shaped cribbage boards.
-I attached the arms to the backstop with wood screws, pre-drilling the holes on the drill press to prevent splitting.
-Make sure they're square!
Notes on the runners:
-Two runners attached to the jig to fit in the grooves on the drill press will allow you to slide the jig back and forth. This is one area where I sort of free-styled it, and maybe could have found a better technique. I cut the runners to size and screwed them in one at a time (again, pre-drilling holes to prevent splitting) but had trouble getting the second one in the right place. I got frustrated trying to get the second runner in the exact right position and eventually just sanded off a few millimeters with a belt sander until it fit in the groove. The jig isn't a perfect fit in the base, but it's pretty good.
