Eye Splice For Brait (8-Strand Plaited Rope)

Eye Splice for Brait (8-Strand Plaited Rope)Yale Cordage, Inc. 2004Purpose:These instructions detail the procedure to fabricate an eye splice in Yale’s Brait products or anysuitable 8-strand plaited rope. An eye splice is a permanent loop termination that maximizes thebreaking strength of the rope.Yale Products:Nylon BraitPolyester BraitHy-Dee BraitSpun Polyester 8-PlaitTools Needed:Scissors, Swedish fid, measuring tape, adhesive tape, marking pen, twineProcedure:(A) To begin, determine the tail length needed by counting ten “pics” from the bitter end. Measuredistance from end of braid and mark with marking pen. Next, form the desired eye size from thismark towards the standing part of the rope. Secure the eye from slipping with small twine.1 Pic10 Pics

(B) Note that the rope is constructed of eight strands arranged in four strand pairs. Four strands (twostrand pairs) rotate to the right, shown here in gray.1234Strand Pair 1 "Pic"123Rotate 900 (with the standing part as the axis) and note the remaining four strands (two strand pairs)rotate to the left, shown below in white.1234123(C) In making the splice, it is important to remember that the right-laid strand pairs of the tail willfollow the right-laid strand pairs of the standing part, moving away from the eye. Similarly, the leftlaid strand pairs will follow the left-laid strand pairs. The tucks are made where the strands of thestanding part are naturally “tucked” under the opposing strand direction. In the splice region, thesize or volume of the braid geometry is increased (but not changed) by tucking strand pairs of the tailparallel with strand pairs of the standing part.

1) Starting with the leftlaid strand pairs forexample only, (in practiceit is acceptable to startwith either right-laid orleft-laid strands), positionthe eye so that the leftlaid strand pairs arefacing up.2) Mark four left-laidstrands (two pairs) onboth the tail and standingpart of rope – just belowthe twine securing theeye.3) From the marks madein step #2, move to theright laid strands byrotating 90o around thestanding part towards thetail. Position these rightlaid strands to face up byflipping the eye over andthen rotating the insidestrands outward. Markfour right-laid strandsusing the same method asthe left-laid strands.4) Unbraid the strands ofthe tail up to the firstmarked pair. Tape theends of each strand pairtogether and cut throughtape for a clean end.Continue unlaying untilonly the marked right-laidstrand pair furthest fromthe eye is free.

5) Using the "Swedish fid"to create a tunnel, tuckfree right-laid strand pairfrom tail (shown at rightin dark gray) under thenearest left-laid strandpair (of standing part) sothat the pair runs parallelwith the marked right-laidpair of standing part(shown at left in darkgray).6) Free the remainingmarked right-laid strandpair in the tail. (Do notunlay the tail further butrather grab and pull awayfrom the bitter end tofree.) Tuck under thenearest opposing left-laidstrand pair, as before, sothat this marked strandpair lays parallel with thesecond marked strandpair of the standing part.7) Flip the eye over againso that the left-laid,previously markedstrands are up.8) Tuck the marked leftlaid strand pair that isfurthest from the eye first(shown on left in darkgray). Tuck under theright-laid strand pair onthe standing part, so thatit runs parallel to themarked, left-laid strandpair of the standing part(shown on right in darkgray).

9) Tuck the remainingleft-laid strand pair of thetail (shown at left in darkgray with white marks).Tuck under the opposingright-laid strand pair ofthe standing part so thatit runs parallel with themarked, left-laid strandpair of the standing part(closest to the eye).10) Note that all strandpairs have been tuckedonce now. The left-laidstrands should all exit therope on the same side.The right-laid strandsshould exit the rope 1800around the circumferencefrom the left-laid strandsas shown in picture onleft.12) After each strand pairhas 4 “full” tucks. Tapeand cut one strand ofeach strand pair away.Continue with 2* moretucks for each singlestrand now. These areoften referred to as “half”tucks.11) Tuck each strand pairan additional 3* “full”tucks. It is helpful towork one strand directionat a time (right-laid or leftlaid) tucking both strandpairs once and thenswitching to the oppositelaid pairs. Follow thestrand pairs of thestanding part carefully,tuck where the existingstrand pairs are naturally“tucked” under theopposing strand directionin the braid. In this waythe strands of the tail arelaid parallel to the strandsof the standing part,moving away from theeye.13) After 4* “full” tucksand 2* “half” tucks, thesplice is nearly finished.Tape and cut theremaining strands tofinish the splice. Ifdesired, the strand endsmay be "hot cut" andsealed to about 1/4 inch.The tail ends will pullcloser to the braid whenthe splice is loaded andexercised. This retractionis normal unless it resultsin the loss of a "tuck".* Refer to Table 1 for specific splice tuck requirements by rope fiber
