Installing the Carriage on the Base

Cut the support bracket (piece 8) to shape, and drill a 15/32" through-hole where it's indicated on the Drawings. Fasten the bracket to the top of the base right behind the guides. Now make up two bearing blocks (pieces 9). Slip them between the support bracket and the fence braces. These blocks will capture the head of the carriage bolt (piece 10) that moves the carriage back and forth. Mark the center-point for this bolt hole by sticking your 15/32" bit through the hole in the support bracket and pricking the back bearing block. This block receives a 5/16" bolt hole and a counterbore for the bolt head (see Drawings). Drill those holes now. The long carriage bolt will spin inside the bearing blocks if you grind or

Screw one guide to the base, then slip a pair of paper shims between the other guide and the carrier plate before attaching the second guide. The shim space will ensure smooth sliding action.

flush with the edge of the base; we'll call this the "front" edge. Extend the bolt hole in the base up through the plate. You've now created a starting point for routing a 2,/i"-long slot toward the back of the carrier plate (see photo, below). The slot will house a carriage bolt and hold-down knob (pieces 4

and 5) that lock the carriage in place during tenoning operations. Step to your router table and complete that slot. Then, drill a 3/4"-diameter shallow counterbore into the bottom of the base to recess the carriage bolt head.

Next, follow the Drawings to make and attach two fence braces (pieces 6) to the carrier. Their 7V2n-long edges should be flush with its front edge. Slide this carriage assembly back onto the base. Cut and fasten the fence (piece 7) to the fence braces; align its bottom edge with the bottom of the base.

Insert a 15/32" bit through the hole in the support bracket to mark the centerpoint for the bolt that will move the carriage. Drill a 5/16"-diameter hole and bolt-head counterbore in the back block only.
