    Sorry to hear that you are having a hard time, Stig. Didn't you say you went with an experimental treatment? If so, do they have any history or track record that gives them, and you some idea of what to expect?

    Most non-tree climbers are far more comfortable being hard linked to a tree with spurs and flipline than they are hanging from a rope. There is also no need to guess at setting a line in a good safe location, you can just climb up and see what will and won't work. And then there is this USFS training program for those institutes that need federal approval. https://www.fs.fed.us/treeclimbing/

    You are right, Stig, but I've always been surprised that spur climbing has such a backseat in real world rescue talk. It is so industrial and easy to teach, needs only occasional practice to maintain proficiency, has a low cost and dedicated tools that could be kept separate and requires no pre-setup. Seems it would be the fastest, safest way for quick tree entry and rescue.

    DMc replied to a thread This is the Akimbo in Gear Forum
    I run mine with the bottom set 2 holes less friction than the top arm but it will vary. I also do not set the top cam so loose that it is wholly dependent on the spring action to make it work. The Akimbo is so quick and easy to change friction settings, don't waist your time climbing on it if it's not right, even mid climb. One pin hole difference can change things without any great risk in doing so.

    If you look closely at that chart, (assuming I'm reading it right) it shows that the butterfly valve dumps a lot more than the others when it is just beginning to open. Being that it is holding high pressure air, that makes a big difference and gets things going with authority. I really, really want to play around with a coil spring under the valve arm. A trigger would make it way better and its damn good as it is.

    Having the butterfly valve is a huge improved over the ball valve. Not because it is stronger but because it dumps the air chamber faster and with less physical movement. I also agree with OF that launching from a shoulder position is the least consistent. Not a fan of CO2 (as it will change with temperature) for the load force or the use of a red dot sight that limits you to positioning yourself to sight down it. With a 12oz bag and 1.75" zing-it the APTA should reach close to one vertical foot per pound of chamber pressure.

    I'm having a lot of trouble making the math work on this. The plan is to extract a carbon source, using energy to do so, transport it, using energy to do so, and then transport the waste byproduct to land areas and incorporate it, also using energy, but we can still somehow come out carbon negative? Terra preta is a designation of a specific type of soil. It is black and has a high carbon content along with a whole bunch of other stuff. Adding charred by-product to soils of different types has not yet been proven to be across-the-board beneficial nor does it in anyway reduce atmospheric CO2. Not to nicpic but your example of burning a match as being an example of pyrolysis is actually an example of combustion.

    I love science and technology, but that is not what I was questioning. They are like a feast laid before us with unlimited choices and possibilities. Just take a look around and tell me how much collective wisdom is displayed when people have unlimited dietary choices. Has having that made us physically stronger and healthier? I see a common theme of not being able to recognise cause and effect. Do you have any idea how much stronger ancient man was? The very attributes that allowed primitive mankind to flourish are the same ones that have made us weak as adversity has diminished. The strength and fortitude needed to survive and flourish as a family unit back then was nothing short of phenomenal. The need to make things better, safer, stronger, maximize resources was hard-wired into those that survived. They are what still drive us today but what do we have to overcome? Separated from need those same traits are predisposed to overconsumption and insatiable appetite for more and in the easiest way possible. The paradox: the stronger the society the weaker the individual. Weak individuals are what cause societies to collapse.

    Just curious. I have only heard a tone of admiration and possibly a little envy in most of these posts. Not just for the machines but for the people that are, leading the way. Mankind has no set path, just the one it chooses.

    So this all looks good to you, Cory? What happens when you take this a couple steps further? Bigger, faster machines with even more reach and potential. One step more, all industry goes the same way. Sure will make work easy. So easy in fact that the only jobs left will be for people that know about fixing machines. I like what I do now. Doing things in an easier way only works up to a point. After that, lots more people doing nothing.

    Ha! I love the smell of wood smoke, been around it all my life, reminds me of camping. When we built our house over 22 years ago, we installed smoke detectors. Well with an old-fashioned wood cook stove that runs year round, those annoying little bastards didn't last long. Choices we make.

    No one is recommending you give up. There are literally thousands of trees that can be cut that don't involve houses, electrical wires or other fragile obstacles that need to be missed. Work and gain experience with those and you will quickly learn what you can and cannot do. Working safely with trees is like learning any other skill that has a physical component. It takes time and practice.

    I totally agree with the last two posts. You are not being honest with yourself and certainly not with your clients. All the good advice you have been given will do you no good if you lack the ability to evaluate what you are capable of. This is not a game of, I think I can. You need more experience and the smart way to get that is by working your way up slowly. Keep asking questions but you need to be building knowledge and skill upon work you have done not what others have done.
