SLIDE 8

Chopping a mortise in the floating tenon for the

wedge. The board

was too wide to use a mortising

machine. Chop

from both sides and meet in the

middle. Making

the 4” deep mortise accept this tenon was difficult.

SLIDE 9

Box Joint hinge requires 18” straight hole. Too long to bore. Rip into 6” boards: 6” straight hole OK 8’ ancillary fence Paul’s thickness planer caused tear-out. Justify subsequent measure- ments against the top surface and sand later. Used glue-ready Freud rip blade Six floating tenons /rip joint: Justify against top surface. Acetone before epoxy 19”

Final hinge Realize the top surface was sanded flat after the hinge was made.

1” dia. 3/8” dia. 1/2” 3/16” 5/16”

<-Reference Surface, eventual table-top-> Hinge design: the 1” Forstner bit and the 3/8” brad-point bit are aligned to the end and table top surface using brass machinist’s standards.

SLIDE 12

Clamped up for hinge boring using Shopsmith horizontal boring capability.

SLIDE 13

3” deep 1” diameter hole Forstner bit

SLIDE 14

3” deep 1” bore requires a long shank Forstner bit. Without realigning wood or chuck, change to a 3/8” brad point bit for the 6” x 3/8” pivot hole.

SLIDE 15

Bored ends ready for routing

SLIDE 16

Routing the bored ends with a bull-nosed bit referenced against the top’s surface. Ends are mutually aligned with a dowel through the pivot hole. The 36” stretch is protected on the sides with MDF and routed in small increments.

SLIDE 18

Final bull- nosed router cut before inserting floating tenons and edge-gluing pairs of boards.

SLIDE 19

Touching up the hinge with custom-ground carving tool.

Take to industrial surface Sander with the leaves attached by dowels before the final pass.

SLIDE 20

Wenge inlay: dado was made with a track saw followed by routing. Note continuous grain across hinge joint.

SLIDE 21

Mortised cleats affixed with screws near

center. All else

with table-top

fasteners. Note

fastener to bring together separating boards.

Mortises to fit on the tenons on the legs
