Introduction: Table Saw Taper Jig
In this video I’ll show you how to make a taper jig for your table saw and save money. You can also use this jig as a straight line jig or joiner sled. But first I’ll discuss whether you should make your own or build one. For me it made sense to make a DIY jig because it saved money and also had more capability. This is an upgrade over the more expensive one I could have purchased. It’s heavier duty and I can also use this jig for much larger work pieces.
I’ll walk through all the steps to cut all the pieces using my DeWalt table saw and miter saw. Then I’ll assemble and test my new taper jig/joinery sled.

Supplies
3/4" Plywood for base and fence
CA Glue https://amzn.to/3Dx32TG
1/2" Plywood for rail guide
Hold down clamps https://amzn.to/3n0j8yD
T-track w/ hold down knobs https://amzn.to/3BB7SyK
1 1/2" dowel for handle
Wood screws
Step 1: Cut Base & Fence to Size
Using 3/4" plywood, cut the base to 48"x11" and the fence to 46"x4".
Step 2: Install T-tracks
Cut a dado the width of the t-track about 5" from each end of the base board. The t-track should sit flush with the base. Cut and then install the t-track into the dado slots with screws. If the screws poke through the other size, grind them below the surface of the plywood so they do not scratch the table saw.
Step 3: Cut & Install Miter Slot Guide
Using some 1/2" plywood, cut the miter slot guide to be fit in the slot with no slop yet still slide smoothly. It should be just proud of the table, around 1/16". It should be 48" long.
Now, put the guide in the slot and apply CA glue. Then apply accelerator to the bottom of the base where the guide will touch it. Then use the table saw fence as a guide and lay the base onto the guide and apply firm pressure for 30 seconds. The base should be touching the saw blade when installed.
Remove the jig from the saw and drill and countersink holes. Now screw the rail to the base. Make sure the heads of the screws are below the surface of the guide so they do not scratch the table saw.
Step 4: Make Fence
Lay the fence on the base and mark where the t-tracks sit under the fence. Then drill holes 1 1/2" on either side of the mark you just made. The holes should slightly bigger than the hardware for the tightening knob. Now, connect the holes with a jigsaw to create a slot.
Now use a scrap piece of wood to create a stop on the end of the fence as shown.
Step 5: Install Hold Down Clamps
Mark the hole locations of all of your hold down clamps. Predrill holes for the screws. Screw the clamps into place.
Step 6: Make/install Handle
Determine where you want your push handle and mark the location. Then cut a 6" piece of 1 1/2" dowel. Predrill a countersunk hole where you want the handle and then screw the handle to the base. Be sure the head of the screw is below the surface of the base so you don't scratch you table saw.
Step 7: Wax Base
Using paste wax, wax the bottom of the jig and guide rail so it slide smoothly on the table.
Step 8: Test
Clamp a scrap piece of wood into your jig and try to make a taper. This jig can also be used to put a straight edge on a piece of wood that is not straight.
Enjoy your cheaper, better table saw taper jig!
