When I started splicing, I read a couple of tutorials (mostly by Opie) and copied the spliced gear I had. But recently, I have tried to make sure I have it right. Especially the bury lengths. On my whoopie slings, the bury of my fixed eye is 5.9" (15cm) long, including the trimmed part. The bury of the adjustable eye is 9.5" (25cm) long. The bury on my dog bones and locked continuous loops is 3.2" (8cm) long. I don't know why the buries on the original items had these lengths. I simply assumed that the makers knew what they were doing. On Dutch's Amsteel 101 it says
Since I have never seen a dog bone, a continuous loop or a fixed eye of a whoopie sling with 8" buries, I'm not sure that understood the text correctly. I assume that "bury" in this case means the constricting part of the whoopie slings, is that right? What are the other "buries" then called? And is there are rule on how long they should be? If I don't lock my continuous loops, would I need to make each end 8" long, or only 4" because both share the load?What size bury for Amsteel 7/64? Samson specifies that a fid is equal to the diameter of the rope x 21, and that an effective bury for Class 2 rope should be three and a half fids. The diameter of Amsteel 7/64 is 0.11 inches, so for this rope, one fid is equal to 2.31 inches. So the recommended bury would be about 8 inches. Bury = fid x 3.5 = 2.31 x 3.5 = 8.01 inches Note that the length of the bury is dependent on the diameter of the rope. Counter-intuitively, the smaller the diameter of the rope, the shorter the bury needs to be. For example, a whoopie made with 1.75 mm Zing-it would only need five inches of bury (if following Samson specs), while one made with 1/8 inch Amsteel would need nine inches.
