Make the end cap out of two pieces as shown in the drawings. Cut a groove along the inside edge of the outer piece, to fit a tongue on the edge of the bench top itself. Make this tongue along the bench top edge with a router and a straight flute bit. Clamp a fence to the top to guide the router and limit its cut. Bore a hole in the end cap on the drill press for the screw to fit. Take extra care that this hole is bored at 90o. Tap the hole for threads as in photo 8.
Laminate together pieces for the front bench section, as described in the project in this site on making a Traditional Workbench. However, this front section differs from the other bench slabs in several respects, it is much thicker, not as wide, and has the fixed jaw with its finger joint. Bore holes into the layers for threaded rods that will hold all the top sections together, as described in the Traditional Workbench project on this site.
||Photo 4- Laminate together a front section for the bench, incorporating within this section slots for bench dogs. Nail the short parts between slots in place during the glue up to hold them steady while clamped.
Incorporate into these laminations bench dog slots by spacing short pieces closely together as in photo 4. Ensure that the pieces are uniformly spaced by making a spacer that you place between them as they are located on the lamination. Nail down each section in its proper location during the glue up, then proceed with gluing and clamping the remainder of the pieces.
||Photo 5- Fit the tail vise to the bench top with the all the top pieces bolted together, and the whole top placed upside down. Check that the guide bar slides easily in its notch in the end cap.
Glue the front of the moving jaw to the inside moving jaw, taking care to align the two dados for the dog slot. Join the front bench section to the other sections with a dozen dowels as discussed above, then bolt together all the bench top sections and turn them upside down. Fix the end cap onto the end with short threaded rod sections as in photo 5. Put the tail vise in place as shown in that photo.
