Whoopie slings are adjustable slings constructed with a non-adjustable eye at one end and an adjustable loop/eye at the opposite end. These splicing instructions are intended for use with SupreemX-12™ made with Dyneema® fibre and other 12-strand ropes made with high-modulus fibres such as Vectran®, Technora® and Kevlar®.
If you are making a Whoopie out of our Static-12, Static-12DS rope or another rope made with polyester or nylon, you could use the standard instructions for a Whoopie Sling.
It is important to note that when we reference a “fid” or a number of “fid lengths” within these splicing instructions, we are referring to a “full fid length” which is calculated at 21 x the rope diameter. If you are using fids for your measurements, you must be sure to account for the type of fid you are using i.e. “half 10.5x, long 14x or full fids 21x”.
Note: Shorter measurements have been used in the photos for photographic reasons.
Make a “taper mark” ½ a fid length (10.5 times the diameter of the rope) from the bitter end, then make “mark 1” 2 fid lengths (42 times the diameter) from the bitter end. Form the desired eye and make “mark 2” opposite of “mark 1″.
Place the bitter end of the rope in the fid.
Pass the fid through the centre of the rope at “mark 2”.
Make “mark 1” ½ a fid length away (10.5x the diameter) from the bitter end.
Make “mark 2” ¼ of a fid length (5x) from “mark 1”. Alternatively, if you want a longer handle, make this mark at a ½ fid length.
Insert the fid into the rope at “mark 1” and run it up the hollow middle of the rope the short distance to “mark 2”. Position the fid so that the bitter end can be placed in the fid.
Start pulling the fid through.
Continue pulling the fid through until the bitter end is fully exposed and the back splice is tight.
Remove the fid.
Cut the bitter end off where it exits. We prefer to make a straight cut as opposed to an angled cut. …Cutting the tail in this way should decrease the likelihood of the back splice termination being pulled back into the middle of the rope.
Milk the rope to hide the cut end and finish the back splice handle.
