Another way......we braided cat-5 in no time like this.
Nail on my deck rail....attach all 3 of your lines to the nail.
Roll up one line on a 8" dowel, take the other 2 lines and attach the free ends
to a 24" dowel, one line to each end. Stand back your 25' with the longer dowel and make the 2 lines taught.
Holding the 24" dowel in your fist simply turn it to the right, the other guy feeds the 8"dowel down between the other 2 lines, then you turn the 24" dowel to the left and then he feeds the 8" dowel up....repeat over and over. This will give you a nice tight even braid. 25' will take about 10 min.
These will take a bit longer.....
