I hope this instructable helps those who wish to make their own jig for making paracord items. I made this jig with wood that I had laying around to handle three different size buckles and two pins. It can make up to an 18" bracelet, collar, key fob, etc.
My wood working skills are mediocre at best, and I was limited on my time to complete the jig, so I apologize in advance that I do not have pictures of every single step. But I believe I may have enough to help you through making a jig of your own!
The first two buckles are your common 3/8 and 1" buckles, The third buckle is a whistle/scrapper/flint rod buckle that I ordered off line. I also added in two pins that are roughly 2.5" long, 1/4" diameter.
