    Humans may have first walked upright in the trees

    Also here is an awesome old clip of a traditional tree climbing technique, a variant on one of the ones outlined in the first post. This old guy makes a loop for his feet to improve his footlock. Dont miss the end its pretty crazy. Getting into a different vein, the traditional Japanese...

    Just starting out, questions about setting up a minimal business and insurance

    I have eight years of climbing experience and was thinking about setting my own thing up legally, just for a minimal truck and trailer operation with a friend. Have done a ton of cash work with no real business setup but want to start getting all that squared away. I have a a lot of...

    Which Knee Ascender in 2022?

    I totally agree I just think he is intimdated by everything else there is to learn, I think homebrew gear even more so. I didnt see the foldable anywhere, and didnt expect to find the reg saka anywhere, Mumford said he has been waiting on new stock for a year, supply chain issue. I just...

    Which Knee Ascender in 2022?

    I actually make my own diy one, rigid and no bungee, I don't think the new climber wants to learn to splice unfortunately, mostly a rec climber.

    Which Knee Ascender in 2022?

    It looks like the SAKA is out of stock indefinitely. I'm trying to get someone started climbing. What is second best?

    Airsoft dump pouch

    I've had a few climbing pouches and this is my favorite. It has a stiff plastic 'hoop' opening, bungee drawstring top, huge inside, cordura fabric. With 4 caritool clips on my Treemotion and it fits nicely in the middle, very easy to fish out gear without really digging or dumping out other...

    vvvvvvvvvvvvvvv

    Yes, it's basically just a Petzl Basic with hollow tube webbing, stiffened with coat hanger wire that has its ends rolled over and stuck into the knots. Foot loop is improved with bungee cord, a piece of stiff leather and some change sleeve so it forms a good stirrup that cinches on the shoe...

    Raccoon Ringworm parasite in the work environment

    https://www.cdc.gov/parasites/baylisascaris/index.html I recently handled a baby raccoon that was found in a hollow tree we felled. I was vaguely aware of this disease but after a lot of reading I think all arborists should be aware of it. Most raccoons are infected and can be shedding...

    Air pollution from saws and machinery

    I'm just wondering if anyone has looked into this themselves. I spend all day running a chainsaw or operating a diesel Kubota (we do land clearing for power lines) and want to look into this. I know exposure isn't that high, but it's chronic and over a career, and at higher levels than most...

    3M Peltor WS-CUSH Bluetooth Headset

    Sorry, the military headset I got for the range. It has a weird plug to connect to a radio that is bigger than a 3.5mm you see on headphones. The headset I got for shooting used for under $150 on eBay was a MSA Sordin Supreme Pro, here is the style that might work with work helmets. Probably...

    3M Peltor WS-CUSH Bluetooth Headset

    I feel like I ran across that, there's made in China versions of all the tectical gear for them. The thing about military headsets is I don't think that they'll interface with our helmets.l directly. Different attachment style. Could be wrong. The way around that is a behind the head style...

    grinding bamboo roots

    My first thought was solarize the soil with a heavy black plastic barrier, but I bet those growing points will punch through. This could still really stress it out in the summer heat. Solarization cooks everything in the top of the soil, even seeds. You might dig down and assess how deep the...

    3M Peltor WS-CUSH Bluetooth Headset

    https://www.envirosafetyproducts.com/3m-peltor-ws-cush-wireless-communication-x-series-earmuff-bluetooth-accessory.html This seems promising if the physical button on the muff can activate a walkie-talkie phone app like Zello. A phone is required for it to work at all, but I think Zello can...
