With the two carriage bolts recessed into the lower half of the jointer jig, turn the base over and attach the upper half of the jig by positioning the slots over the bolts. Complete the assembly by adding a flat washer, then a lock washer and a wing nut to each bolt.
At this point, verify that the upper half will slide evenly against the lower half and that it can be securely held in a given position by tightening the wing nuts.
