ROPE. MAKING. 



Suppofe you want to make a rope either cable or haw- 

 fer-laid, to be tapered one-third the length, and one-third 

 the fize; you muft refer to Table V. or XIV for making 

 taper-cable, or hawfer-laid cordage, two-thirds the length 

 and two-thirds the iize, which you mull work almoft wholly 

 the reverfe way, by working the number of threads there 

 mentioned to bfc worked in the tapers in the (hank, and the 

 number of threads in the (hank muft be worked in the ta- 

 pers : the length of yarn there mentioned to be tapered muft 

 be the length in the head to the firft taper, and the length 



there mentioned in the head muft be the length of the yarn 

 to be tapered : the length of yarn requefted to be warped 

 for the (hank will be the fame as there mentioned, and the 

 diftance between the tapers will, in almoft all cafes, be the 

 fame as there nominated ; but if at any time there mould be 

 a difference, and you are at a lofs to find the diftance be- 

 tween the tapers you muft divide the length of yarn to be 

 tapered by the number of threads you have to taper, and 

 that will give the exaft diftance between them. 



Table XVI. 



Table XVII. 



Shewing the Number of Threads to work per Hook for four- 

 ftrand hawfer-laid Cordage, from 2 to 12 Inches in Circum- 

 ference, of the Sizes of Yarn as undermentioned : the Ropes 

 to be laid without Hearts, the Yarns comprifing which being 

 equally divided in the Strands. 



Shewing the Length of Yarn requefted to be 

 warped for the undermentioned Lengths of 

 four-ftrand hawfer-laid Con ige, with the 

 Hardening Mark prefixed againft each refpedtive 

 Length. 



Remarks. — It is very feldom that hawfer-laid cordage is 

 compofed of more than four ftrands, but for the fake of 

 experiment, or otherwife, it might be demanded to contain 

 a greater number : as fuch, the following rule, carefully 

 attended to, will inform our readers how to lay a haw- 

 fer-laid rope in as many ftrands as may be confidered ex- 

 pedient. 



Suppofe you want a five-ftrand hawfer-laid rope, you 

 muft fquare the fize of the rope propofed to be made ; that 

 produft multiply by the fize yarn you propofe making 

 your rope from ; the product of which, divided by 15, will 

 give he number of threads to work per hook for a five- 

 ftra . ■-: iwfer-laid rope If you want to make a fix-ftrand 

 hawf~r-laid-rope, you muft proceed as above, and divide 

 by j8; if a feven-ftrand, divide by 21 ; if an eight-itrand, 

 by 24 ; and fo on, adding 3 to your divifor for every ftrand 

 you mean to increafe in the rope. 



The fhrinking proportion in making four-ftrand hawfer- 



laid cordage, in the firft procefs, is exaftly the fame 

 as in three-ftrand ; the Only difference is in clofing the 

 rope, which, being compofed of four ftrands, occafions 

 the rope to lay more round and clofe than in three- 

 ftrand cordage, which makes the fhrinkage be in a much 

 greater proportion. The rope, in clofing, will fhorten 

 -rVth parts of the remaining length of yarn, after the 

 rope is hard, inftead of ith, as in three-ftrand hawfer-laid 

 cordage. 



The weight of each coil of four ftrand hawfer-laid 

 cordage may be nearly afcertained, by referring to the table 

 of the weight of three-ftrand (Table XII.), there being as 

 near *.he number of threads in each fize rope as can polfibly 

 be laid, for each ftrand to have an equal number. But it 

 mould be remembered, that a coil of four-ftrand hawfer-laid 

 rope, made out of 200 fathoms of yarn, will be only 130 

 fathoms long, inftead of 1 33.2, as in three-ftrand hawfer- 

 laid cordage.
