Bino, I watched all your videos and all were helpful, useful and helped me to learn what I could not in a book. You should really open a small school for Arborist. I am from Denver, Colorado and would take a few months to participate in your class. Colorado offers little to none and are personally selected when something comes about. Well thank you for the videos and keep them going cause many of us find this as a second hand tutorial but me, it is first hand. Take care and be safe.
I made one similar to yours. I used a nylon foot loop since I do not have boots with the loop. I also added an elastic velcro strap to hold the knee ascender to my leg when I am walking around without being attached to the climbing system. I also used a double bungie setup. I looped mine through a small quick link attached to the top of the ascender. It acts as a pulley for the cord.
I found out today a an oak tree about 48” in diameter is no place to try to learn to gaff your way up when you have never done it before. I got on but couldn’t get a flip. Had to be a crack up for the neighbors. I got my thro line through send toss, but it’s too brush below that fork to let my friction saver go past. Now I’ll be going up almost to that height on a 24’ ladder to handsaw all those little branches off to get my rigging through. What a crack up.
I used theraband from Amazon for mine. I used bungee cords first but they stretched out and broke shortly after. I used para cord for the non stretch portion and doubled it to help strengthen it
My knee ascender is set up the same. Between ascents, I click from the boot, pass around your back and clip to your chest harness. Way easier than dealing with the commercial brands
