head in a table saw. Cut a 3/4" x 3/4" notch on the end of the swing arms to mate with the flip-out support.
The last thing to do to the arms is to round off the corners: 1" on the ends and 31/2" on the brackets. Now mount the swing-arm assemblies to the underside of the wings using a 10" piece of continuous hinge, with the notched end of the swing arm H" in from the point where the wing meets the case. To keep everything from flopping around when the arms are down, use adhesive-backed Velcro between the swing arms and wings. Reinforce the Velcro's adhesive with staples.
Finish the wings by cutting a 3/s" x 3/4" dado down the middle of the wing for the extruded aluminum channel for the stop. Next to that dado, cut a second shallow dado that's 1/2" wide and as deep as your stick-on measuring tape is thick. Cut the aluminum channel to length and screw it in place.
Now concentrate on the flip-out supports. After cutting out the mating notches for the swing arms, cut a x 5/8" rabbet into the end of the support to accept a 43/4"-long piece of continuous hinge. Lay out and mount the support to the upright, centered and flush to the bottom edge.
The last step on the wings is to attach the wing assembly to the upright. Do this carefully so that the surface of the wing is flush with the upright ledge. Now, if everything's OK, your wings should lock flush and square to the upright. If you didn't get it right the first time, add a flat-head screw to the inside of each notch and you will be able to adjust the height of the wing.
To attach the wing assemblies, temporarily remove the saw/riser assembly and remove the wing from the upright assembly. Cut a spacer that's
23/4" plus the height of the saw's table. Clamp the spacer flush to the upright ledge. Lay the wing assembly on the edge of the case. On the saw/riser assembly, measure from the front edge of the riser to the saw fence. Subtract 13/4" from that number and mark it on the case, measuring from the front. This is where the upright should be mounted. It accounts for the thickness of the 3/4" saw fence and the distance from the center of the stop to the fence. Mount the upright with the hardware listed. Make sure to coun-terbore the bolt heads and washers. This allows the flip-out support to fold flat against
