  1. Lashing

  2. Lashing • A means of fastening two poles (or spars) together Qualities of a Good Lashing • Firmness – it should be string and tight, or else it is likely to fall apart when put under strain • Neatness – proper steps should be observe because incorrect lashing can easily loosen Knots and Hitches used in Lashing • Stopper Knots – used to lock and prevent slipping of a clove hitch • Example: Overhand, Figure of Eight, etc. • Clove Hitch – used to start and finished almost all lashing • Timber Hitch – Used to start a diagonal lashing because of it’s ability to tighten. Parts of Lashing • Wrapping – for connection • Frapping – for tightening

  3. Kinds of Lashings • Diagonal Lashing • Square Lashing • Shear Lashing • Round Lashing • Figure Of Eight Lashing • Continuous Lashing • Malay Hitch

  4. A. Diagonal Lashing • Used where two spars are likely to be pulled apart • Procedure • Start with the timber hitch along the two spars • Wrap at least 3 times along each of the diagonal s of the spars • Frap at least 3 times between two spars • End with a Clove Hitch in any of the spars • Lock with a stoppers knot

  6. B. Square Lashing • Used where 2 spars cross one another and have to be joined, or where the load on one spars might tend to make a slip over the other • Procedure • Start with clove hitch along one spar • Wrap at least 3 times around both spars alternately (over and under) • Frap at least 3 times between 2 spars • End with a clove hitch along the other spar • Lock with a stopper knot

  8. C. Shear Lashing • Used for spars which will either lift or support weights. Where it’s used to join two spars to increase overall length • Procedure • Start with a clove hitch along one spar • Wrap at least 4 times around both spars • Frap at least 3 times between 2 spars • The frapping turns will be difficult to do. In this case, drive in wedges between 2 spars to leave space. • End with a clove hitch on the other spar • Lock with a stopper knot

  10. D. Round Lashing • It is used to join or connect two spars to increase overall length • Procedure • Almost the same as in shear lashing. • Frapping is not applied, and both spars will be tied with a clove hitch

  12. E. Figure of Eight Lashing • Used for joining three or more spars together • Most useful for doing tripods • Procedure • Start with a clove hitch along one poles • Wrap at least 3 times around the spars alternatingly (over and under) • Frap at least 3 times between the spars • End with a clove hitch along the other end of the spar • Lock with a stopper knot

  14. F. Continuous Lashing • Used in joining a number of spars or strips along a single spar or support • Most useful in making mating for tables, etc. • Procedure • Make a bight along the center of the rope • Knowing the center of the rope, make a Clove Hitch along the center and tie it on the spar support • Lie perpendicularly along the support the spars to be tied • With the 2 end rope, go over the spar and cross under the support. Continue until all spars are tied to the support • End each end rope with a Clove Hitch • Lock with a stopper knot

  16. G. Malay Hitch • Used in joining several pieces of spars along each other without a support • Most useful in making matings for camp tables, towers, etc. before a camp and then rolled up for portability • Procedure • Make a bight along the center of the rope • Knowing the center, make a Clove Hitch and tie it around the 1st spar • With the 1st end rope, go over and around the 2nd spar and to the 3rd and so on in a circular motion • Do the same process with the 2nd end rope, but instead of going over, go under the second spar making it alternate to each other • Finish both end ropes with a Clove Hitch along the last spar • Lock with a stopper knot
