The last step in building the table saw jointer jig is to trim the edge of the jig.
With the table saw blade beneath the surface of the saw, position the miter strip into the miter slot and verify that the jointer jig glides smoothly across the entire length of the table, with very minimal side-to-side play. If you experience side-to-side play, you may wish to go back a couple of steps and make a slightly tighter miter strip.
Once you're satisfied with the movement of the jointer jig, pull the jig all the way forward (toward your body), raise the blade a little over 3/4", start the saw and trim the right-side edge of the jointer jig.
Your table saw jointer jig is now complete. To use the jig, position a board that you want to square up into the jig, with the parts of the board that you want to remove just over the right-side edge of the jig. You may need to adjust the wing nuts to widen or narrow the jig's clamps to accommodate boards of various widths.
With the jig adjusted and the board clamped in the desired position, raise the blade to a height just above the stock, start the saw and trim the stock. As with any table saw operation, do not stand directly behind the blade, but off to the left-side, just in case of a kickback.
To trim the opposite side of the stock (so the board's edges will be parallel), simply use the table saw with the fence. You only need the table saw jointer jig to straighten one edge of the board.
TIP: Keep in mind that this jig, as it is configured in these plans, is for a board no longer than four feet in length. For longer boards, you may wish to make a longer jig.
