A blog reader had seen my posts on making lanyards with a knitting spool and made some of his own spools using aluminum. He kindly sent me one, and I have to say it's built like a tank and should last a lifetime.
It's perfect for 2mm and 1/16" sized cord, like the 'Type I' paracord/accessory/dummy cord, that I like to use, as well as mason's line. I tried it out on some orange mason line, for a neck lanyard, and it works great.
Thanks Bennie, I appreciate it, Semper Fi!
