                                           The seI7.;agee,  salvagee  or warped strap  is  a  skein or coil of mar-




                                    line  or rope  yarn  that  is  laid  up  as  smoothly  as  possible,  generally




                                   around  two  belaying  pins,  and  then  is  marled  over.  Made  in  this




                                    way, the strap is  used  to wrap around stays to hook a  block to and,



                                   being  much softer  than  rope,  it  has  a  better cling.  Small  selvagees,





                                   served  or grafted  over,  are  used  for  block straps.  Large  ones,  simi-



                                    larly  made  but not served,  are  used  for  cargo  slings.  They are  soft




                                   and pliant, and do not mar the cargo.




                                           3148.  A  strap with a large eye is  used for either toggling or lash-                                                                                                                                                                                                                                                                                                            31~9

                                           3149.  A  selvagee  for  a  block  strap  is  parceled  and  served  over




                                    (two processes described later in the chapter). This illustration shows




                                    an  old  block,  with  selvagee  strap,  turned  in  with  a  throat  seizing

                                    spun yarn and seized snugly around the block with a  round seizing.                                                                                                                                                                                                                              3150




                                    The yarns  are  opened and  scraped  down,  so  that  the  length  tapers



                                    very moderately to a  point. It is  then carefully marled  ('# 3 II 5). A

                                    are stuck only once. They are then scraped  down and a  round seiz-

                                    is put on ('# 345 3) and then the rope is made into seven foxes, tapered




                                    and platted.




                                            3152.  A  double  tail  block may be made either selvagee-fashion or

                                            3153.  The oldest method of strapping a block, and one that is  still




                                    used,  was  with  a  R1GGER'S  SHORT  SPLICE  (#2648).  The  splice  was




                                    always  placed at the breech of the block.
