Celtic Knot Patterns #1: Simple Double Knot - I think...

Howdy Lumberjocks,

I’m trying to figure out a simple Celtic Knot pattern for a living room cocktail table. I think I have crunched it down to something workable. If you see a hole in my thinking, please let me know. I’d rather fix it now than throw away time and wood.

For starters, I tried to remove complications by sticking to a formula. It’s really kind of important that I have this right because I’m sharing it. PLEASE share if the formula is incorrect.

Board width = W
Length is always a multiple of W

If that is true then, 1a and 1b from my image are 3W or 3 times width.

Please double check me before starting or confirm my findings on the finished size. I’ve been wrong before.

Finished size:
Width = approx 7.07107W
Length = approx 12.727926W

Here is the plan for the design. Do what you wish with it.

All lengths represent the long side of every board.

1a and 1b.
1 each
3W
square ends

2a and 2b
4 each
4W
1 square cut on end
1 45 degree cut other end (All eight boards match each other. If you are not doing any non binary layering, there are no offcuts)

3a and 3b
2 each
4w
2 45 degrees cuts toward center.

4a and 4b
2 each
3W
1 square cut on one end
1 45 degree cut on other end (Miter saw is reversed from 2a and 2b.

5a and 5b
3 each
1W
1 square cut on one end
1 45 degree cut on other end (Miter saw is reversed from 2a and 2b.
Off cuts from 3a and 3b and 4a and 4b may be used

-- Learning is like a door. Open it and there are hundreds more on the other side. Thanks for all the lessons!
