## Abstract

In some embodiments, a durable solid-wood door or other rigid block assembly includes two generally-planar, mutually-parallel solid-wood boards each having a plurality of mutually-parallel dovetail-connection channels running generally along an internal surface of each of the boards, and a solid-wood central keying structure disposed between the two solid-wood boards. The central keying structure includes a plurality of two-sided sliding dovetails keys sized to slide within the dovetail-connection channels to secure the two-mutually-parallel solid-wood boards to each other via sliding dovetail connections to the central keying structure. Alternating wood grain orientations may be used to reduce warping. Each board may include multiple laterally-adjacent monolithic slabs interconnected via tongue-and-groove edge connections, with the dovetail connection channels extending across multiple slabs. An adhesive and/or fasteners secure the two boards in a fixed position relative to each other, creating a solid block structure.

## Claims

### Claim 1

A solid-wood rigid block assembly comprising:
two generally-planar, mutually parallel solid-wood boards each having a plurality of mutually-parallel dovetail-connection channels running generally along an internal major surface of each of the boards; and
a solid-wood central keying structure disposed between the two mutually-parallel solid-wood boards, the central keying structure comprising a plurality of two-sided sliding dovetail keys sized to slide within the dovetail-connection channels to secure the two-mutually-parallel solid-wood boards to each other via sliding dovetail connections to the central keying structure.

### Claim 2 (depends on 1)

The solid-wood assembly of claim 1, wherein the solid-wood assembly forms at least part of a door.

### Claim 3 (depends on 1)

The solid-wood assembly of claim 1, wherein the solid-wood assembly forms at least part of a doorjamb.

### Claim 4 (depends on 1)

The solid-wood assembly of claim 1, wherein the solid-wood assembly forms a body of a tabletop.

### Claim 5 (depends on 29)

The solid-wood assembly of claim 29, wherein the laterally-adjacent solid-wood slabs are interconnected by tongue-and-groove connections.

### Claim 6 (depends on 1)

The solid-wood assembly of claim 1, wherein a wood grain direction of the central keying structure is transverse to a wood grain direction of at least one of the two mutually-parallel solid-wood boards.

### Claim 7 (depends on 1)

The solid wood assembly of claim 1, wherein the major surface has a length and a width, and wherein the plurality of mutually-parallel dovetail-connection channels extend generally along the width of the major surface.

### Claim 8 (depends on 1)

The solid-wood assembly of claim 1, wherein each the solid-wood boards and sliding dovetail keys are made of rift-sawn or quarter-sawn wood.

### Claim 9 (depends on 1)

The solid-wood assembly of claim 1, wherein each of the dovetail-connection channels is tapered along a length of the channel, to facilitate a sliding insertion of a dovetail key into the channel.

### Claim 10 (depends on 1)

The solid-wood assembly of claim 1, wherein the dovetail-connection channels have a depth between ¼″ and 1″.
