    Compact Bulldog Bone

    Update on the 9mm bollards after a climb top rope soloing. So far worked great on the 8.9mm rope. It will occasionally (~1/10 falls) slip through the device for and let you drop 3-8 inches when falling before it catches. Same with the 9.8mm. I used a microtraxion as a backup and it will...

    Compact Bulldog Bone

    I received my 9mm rope bollards mod for the bone this evening. Got it for top rope solo rock climbing. Seems to work good with my 8.9mm rope (tiny bit of creep) and good with my 9.7mm after the profile is flattened a bit. I didn't want to bug Gordon regarding the taper pins so thought I'd share...

    Trunk Injections are the reason we have lost so many Trees to EAB, and Oak Wilt.

    Yeah, wedge was pretty bad in my experience.

    All your evil lies

    Yep... Two parties/gov would likely benefit from a little shake up. They're so obviously corrupted and hurtful to America. We can do better than these two...

    obtaining chems from plastic chemical bottles

    Yeah, I do municipal work so usually large mixes. I keep a little safari and 2f or dominion 2L or around for small jobs or some canopy sprays. Although probably 90% of treatments are trunk injections anyways.

    obtaining chems from plastic chemical bottles

    Agree with ATH. I might leave some water out before triple rinsing the measuring cup and adding that into the mixture. I would note that for soil drench/injections, the Xytect 2f rate is pretty high. I prefer the Xytect 75 in water soluble packets (wsp). Just throw them in per label rate and...

    Sticht Hitch

    Thanks for sharing! Seems to tend better than the ring versión did for me. Not sure I got the bottom part 100% correct but seems to work good.

    Reductions.. is 10% too much?

    30 year weather history is the "normal" from my understanding. Definitely global weirding lately though.. I've heard some weird stuff of about fire insurance but have not been personally impacted nor know anyone that's dealt with issues other than at times ridiculous costs.

    Reductions.. is 10% too much?

    Thanks, sounds like your on the right train of thought with all this. Snow and ice are kinda out of my comfort realm but I generally would ask do we even "need" to do anything. Is there a risk that exceeds the clients threshold? How frequent are these failures and to what size diameter wood...

    Reductions.. is 10% too much?

    Not sure, I haven't read through it in a while. Link doesn't want to work for me.

    Reductions.. is 10% too much?

    Here's my response from another post: "The amount of branch reduction necessary is relatively small. The results of the test of branch reduction under snow loading indicate that a reduction of 15% will reduce load- induced stress in the Critical Fracture Zone by approximately 40%. This is...

    “Rope Only” Canopy Anchor??

    Cool! Hey what benefits do you see over the daisy chain hitch with this? Only real one I see is that it because it's a bowline it might be more accepted within the industry.

    Why tie instead of rigging carabiner?

    From Tree Buzz, whole description and discussion in the thread. That's just the first I saw come up in a quick search. Negative rigging sappy pines from what I recall, definitely abused. I did miss read though (no half hitch) which makes more sense.

    Why tie instead of rigging carabiner?

    Here's from another thread, 50kn steel biner snapped rigging this log with a half hitch (edit no half hitch).

    Why tie instead of rigging carabiner?

    Using it as a slackline anchor sorta like this photo but steel ring and 72 kn Omega steel locking biner that was double checked beforehand. Other side was connected to choked off spanset. Not ideal but was common practice back in the day and still is for small park lines. Biner exploded during a...

    Why tie instead of rigging carabiner?

    I see what you're saying and partially agree but did you watch the video or see the photo? He literally choked off a larger chunk of wood as well. I'm pretty certain arborists have broken biners used in similar choking configurations for rigging (larger wood). At the very least deformed them. I...

    Why tie instead of rigging carabiner?

    I feel like it's totally relevant to the thread/discussion of rigging carabineers as well as tree work in general. Some people really push the limitations of using rigging carabiners to choke off wood/limbs . It's cool and informative to see the failures play out with force data with discussion...
