A killick is "a small anchor or weight for mooring a boat, sometimes consisting of a stone secured by pieces of wood". [8] This can also prevent the timber hitch from rolling. [ 3 ] The timber hitch is one of the few knots that can easily be tied in a chain, [ citation needed ] leading to its use in applications where ropes lack the necessary ...
A knot on the upper side is compressed, while one on the lower side is subjected to tension. If there is a season check in the knot, as is often the case, it will offer little resistance to this tensile stress. Small knots may be located along the neutral plane of a beam and increase the strength by preventing longitudinal shearing. Knots in a ...
Three types of branch attachment are recognized due to differences in the anatomical position of buds that form them. Two key components contribute to the mechanical strength and toughness of the attachment: interlocking wood grain at the top of the attachment and an embedded knot that often lies within the attachment. A common malformation of ...
Burl wood is very hard to work with hand tools or on a lathe, because its grain is twisted and interlocked, causing it to chip and shatter unpredictably. This "wild grain" makes burl wood extremely dense and resistant to splitting, which made it valued for bowls, mallets, mauls and "beetles" or "beadles" for hammering chisels and driving wooden ...
Knot board [] on Elbe 1 (ship, 1965). A knot is an intentional complication in cordage [1] which may be practical or decorative, or both. Practical knots are classified by function, including hitches, bends, loop knots, and splices: a hitch fastens a rope to another object; a bend fastens two ends of a rope to each another; a loop knot is any knot creating a loop; and splice denotes any multi ...
Wood from other locations can also be used, such as the joints where limbs intersect the trunk. Although most resinous pines can produce fatwood, in the southeastern United States the wood is commonly associated with longleaf pine ( Pinus palustris ), which historically was highly valued for its high pitch production.
