Claims3
A method of forming a watertight plank section, comprising the steps of:
- a) sawing green wood planks, including the heart of the log adjacent one side of the plank;
- b) machining some of the planks to include a groove on each edge;
- c) machining some of the planks to include a tongue on each edge;
- d) cutting cross grooves in one side of each plank, with the cross grooves being on the heart side of planks with two tongues and/or the opposite side of plank with two grooves;
- e) fabricating a section, placing a plurality of planks on a surface, heart's alternating, tongue to groove with the cross grooves facing upwardly;
- f) clamping the planks forcing adjacent tongues and grooves to mate;
- g) securing the planks by fastening dry wood cross ties in each of the cross grooves;
- and
- h) drying the section forcing the tongues against one side of the groove forming a watertight seal.
