Things You'll Need
Instructions
Measure and mark the end of the block 1/2 inch from each side. Using the ruler, draw straight lines to form a cross on both of the block ends. The parallel lines will be centered and 1/4 inch apart.
Draw the lines extending down the length of the block on all four sides. You should have two parallel lines 1/4-inch apart down the center of each side.
Cut the corners off of the block lengthwise so you end up with a long octagon.
Run the blade of your knife down the lines on each side, being careful not to cut beyond where the lines will meet in the middle. Remove all of the wood from these areas leaving you with a long cross shape.
Draw the interlocking links on the cross shape. Draw two vertical links that meet in the center of the single horizontal link.
Shade the areas you need to remove to finish forming each link. Use the knife and hobby knife to remove all the shaded areas.
Using a very sharp and thin knife blade, separate the two vertical links from the horizontal link and from each other.
Using careful strokes with the knife, clean up any rough spots.
