Planer face-joint­ing jig and more.

Most ev­ery board re­quires flat­ten­ing on one side be­fore plan­ing it to thick­ness. And that’s easy to do if you have a join­ter wide enough for the job, but many of us don’t en­joy that lux­ury. For­tu­nately, with this sim­ple jig, you can skip the join­ter and suc­cess­fully joint one face us­ing a bench­top planer.

To build the jig, lam­i­nate two lay­ers of ⁄4"

3 ply­wood—do­ing that en­sures a flat base with suf­fi­cient stock for the threaded dow­els to bite into. (I sized the jig to fit through my planer, but you can ad­just its di­men­sions to suit your needs. The jig and work­piece can be a heavy load, so con­sider care­fully be­fore mak­ing it more than 4' long.) Space the rows of threaded dow­els about ev­ery 10", and in­clude one row of 3⁄4" holes near the cen­ter to use with a short dowel and wedge to se­cure the work­piece.

I made the 5⁄8" threaded dow­els and holes us­ing a Beall Wood Threader (beall­tool.com), but you can buy kits to thread dow­els by hand or with a router. Or, buy birch rod al­ready threaded (hard­ware­tree.com), and sim­ply pur­chase taps for thread­ing the holes. Put paraf­fin wax on the threaded dow­els to keep them from mov­ing dur­ing use.

To use the jig, place the board on a flat sur­face. Po­si­tion the jig up­side down on top of the board, and use a screw­driver to ad­just the threaded dow­els up and down to level the jig to the flat sur­face. Flip ev­ery­thing over, se­cure the board us­ing a wedge, and feed the assem­bly into the planer, un­stopped end first. For best re­sults, feed the low end of the assem­bly into the planer first—do­ing that may re­quire flip­ping the board in the jig and relevel­ing.
