5.5 Milimeters (5.5mm)

After some thought, review and more review, and discussion, I decided to go 5.5 millimeter (mm) diameter rope from MOco Jute, a Nawashi, rope artist highly recommended for a source.

It’s common for a rope strand to be 6mm; however, I went for the median as I liked the rope I used with Kasami-San during my instructionsls with her in Nagoya, Jp.

Kasami-San, who is training under Naka-San, whom  approved a 5mm rope also with MOco Jute, I thought I’d go for the in-between. I don’t know; the work just looked so clean and neat with Kasami-San, I figured and hope I figured correctly, that the 5.5 mm will work on my behalf.  
Also, I considered as some prefer the lesser diameter for women, down to 5 mm, as Muraski-sensei stated recently during another instructional. Some say too thin. Given Naka-San’s preference for aesthically enhanced-hojojutsu type style, I may be so wrong here, I thought 5.5mm would work.   I could be totally wrong though!  As I have many-many times. 

Reading up on details provided by MOco of his rope; I quickly gathered what he referring to in his rope construction, in-part because I have an geo-engineering background in installing rock anchors….in my previous PCS blog.

Rock anchors, known as tie-back anchors, are also built of strands and are built for tensil strengths in KiPs to hold a structure in place to competent bedrock.  A Kip is in units of 1,000 pounds per inch.  My rock anchors I approved were steel, 9-strands.

As you see, a rope consists of fibers wrapped into yarns. Each yarn then twists into a strand. Finally a strand is again twisted into a rope known as a hank.  

Hence a #-yarned, #-strand rope….The lay and twist are again detailed. This is as yet for me to fully understand right now.  At least I got some basics.
