    Lightning kills line clearance worker

    If you're working on/near a golf course an alarm goes off if there's a strike within 10 or 20 km can't remember. I've had around 5 such instances. This was discussed before and apparently there's lightning proximity warning apps for your phone. I had one storm roll in so fast by the time I...

    Wildfires

    Maybe what is meant by management is re-plantation practices after 100% deforestation during timber harvesting. Southern Ontario used to have hardwood forests, got stripped out so bad the soil changed to sand dunes (underlying glacial morraine). In the case monoculture conifer was the only...

    Wildfires

    Point to ponder. States forests generally in higher average temperature climate zones so presumably grow more each year. More natural "droppings" to compost. Presume part of climate zone is precipitation? Maybe? So maybe it's droppings rate vs moisture driven composting rate = if "dry"...

    Rigging Point Failure

    Glad to see you're ok. I've only encountered longer sheared branches a few times. They were horizontal and had visible air gaps with partial regrowth, smaller than your branch but surprisingly long split length. I wondered how they still held up. Perhaps tree species that don't callous over...

    Wildfires

    I did a post in a previous fire season explaining that the Canadian forest stretches coast to coast and is so huge that the entire population spread over it couldn't make a dent. And then do what? Cut/rake dead/dry into piles - dump them in a lake? Or do what with it? Nature composts if it's...

    A Discussion on The Fundamentals of Tree Felling

    100' x sin(1 deg) = 100' x 0.017 = 1.7 feet you'd have to watch the top just deflect a bit maybe beside another stationary top for reference. Maybe it's more like 2 deg or 3.5 feet motion. Rough numbers. 5 deg @100' = 8.7 feet. know the feet know the angle Minor concept correction. If...

    Wildfires

    Over 900 wildfires across Canada today. About 200 in Ontario.

    A Discussion on The Fundamentals of Tree Felling

    Looked like it went about 1 degree off vertical before changing course. ? Not much obstacle clearing capability. ?

    A Discussion on The Fundamentals of Tree Felling

    David, 90 degrees course change is like a football player running straight downfield and then abruptly bolting straight for the sideline. 180 is falling forward, stopping mid fall and reversing direction to fall backwards. I think you're mistaken or have misinterpreted. 30 degrees on a clock...

    A Discussion on The Fundamentals of Tree Felling

    How many degrees off axis direction change is achieved using the cut? Pretty sure I've never seen 20 degrees, probably not even 10 degrees. By off axis I mean initial landing spot vs course-changed landing spot. Like clock hands from the stump. ? And how many degrees off vertical does the...

    Wildfires

    Trump wants to put tarriffs on the smoke from the hot-climate-dryness induced forest fires to get cleaner air for the U.S. cities - isn't that concept called a carbon tax? At least he's latched onto the cleaner air part. I jest yet it's eery that it seems like I'm not jesting. Still moderate...

    Bucket Truck Boom Failure

    A week or so back I saw some guys with a shiny new thru-36"-gate tracked lift that had a 2 man bucket. Can't remember the brand. 72 foot

    Wildfires

    On that Thursday smoke map the big purple blob is what I was talking about Wednesday blotting out the sun all day. Thursday we were only 9 or 10/10 crappy air, not 10+. Today the wind shifted the smoke plume a couple hundred km to the west so we have some blue sky and 2/10 air today, but it's...

    A Discussion on The Fundamentals of Tree Felling

    Correct me if I'm wrong. Most species that timber fellers do in the woods are chewy fiber, good hinge-ing. The most common reason to start the fell in one direction and then slightly change it's direction mid-fell is to get it's top/branches past/around a nearby tree while also placing it on...

    light rigging with ring and "figure 8" aka "rescue 8"

    Cool idea. Previously I've heard that using a rescue 8 puts a twist into the rigging line. Have you seen any sign of that? By the way, I carried a figure8 on my saddle for years as a backup emergency descender. Never used it once, finally took it off but it jingled a bit like cowboy spurs...
