    Anyone transition from utility to residential?

    The speccing error was 1) showing/describing what was wanted from one position on the property and 2) evaluating it done from a different viewing position on the property - without letting him know about the alternate evaluation. Words were "you didn't show me this view from here before I...

    Anyone transition from utility to residential?

    I once traded a few bad customer stories with a friend and old people unfortunately came to the fore. He explained about a customer re-speccing after completion and not answering the door presumably on purpose at pay time. I pointed out the likelihood of near deafness. I just had a...

    Hollow codominant

    ATH, understood, a drill bit could even be nominally sized for trunk diameter. This was just a first kick at thresholds which aren't hard numbers anyway. The "alarm" scale is in the operator's head with the colors a general guide eg 1/2 way thru red yup its thin. Buried all the yellow...

    Hollow codominant

    Did y'all get the symbolism of the colors I chose for the ruler scale" YMMV but I guessed 3" shell or less = oh crap, 6" of shell to 3" = considerable concern and 9" to 6" of shell = still to be taken into consideration sometimes. Also 3" is a distance easy to rough out 1" estimations from by...

    Hollow codominant

    On the human resistograph drill bit - maybe red nail polish (durable "paint") on the first 3" of drill web, next 3" orange, another 3" yellow as a visual "how deep is the shell/good wood" gauge. an idea

    Broken man, extreme burnout

    Did you have the fever sweats hallucination dreams? My son just went through that for the first time to my knowledge and it brought back deja vu - wouldn't wish it on anyone.

    Hollow codominant

    If you suspect a commonly occurring species like happened this time, how about becoming a cheap human resistograph drill? Use a small bit like 3/8 or 1/2 and probe with your holes where the hinge cuts are going to be so you aren't removing extra strength. Just an idea. Glad you're ok.

    New device from ISC

    I think the positioning device standard includes a wee bit of drop IIRC 1 m just to not ignore the possibility but not expect it to take multi meter bigger drops. Although intuitively It would be nice to know that it could also take a bigger hit if ever needed. The v3 awah (edit sp) drill...

    The vid I couldn't find had a great mixture of hissing venting cells and popping fireworks cells. The original kick butt A123 18650 cells used by Dewalt were the first more volatile chemistry. The industry has since moved to the less volatile LiFePo with iron formulation. Cell phones and...

    Bandit Chipper possible options - and why.

    What do the parts roughly cost, motor, 2 hoses, valve and gearset? Is it usually a pinion spur set, or is it open worm drive? I'm curious if it's just inertia to go hydraulic because of the existing components or has there ever been electric drives? motor, wires, switch, gearset cost? In...

    The story of saw chain

    I think I saw a web podcast with a fellow who was big on arborist history. He had saddle history, ladder free climb safety rope sequence and I think examples of old saws right from the Swede saw to modern. Middle to "past middle" aged ;) fellow. May have done axes too. I can't recall his...

    Husky new 564 fuel igjected saw

    There's probably a floor or minimum amount to the EFI components weight that adds too much in the current trim. Solenoids and pumps involve copper and steel which are both heavy. I bet someone with an inside scoop would confirm a Stihl push for EFI more across the board but for now they're...

    Battery explosions

    Interesting twist on this is back in 2014 when LiIon battery (drill) powered ascenders happened the comment was raised of a battery going off and frying your textile life support PPE (rope and saddle) and how it was similar to the largely considered/controlled risk of gasoline going off from a...

    Battery explosions

    They're also thermally protected, as a pack connected to the outside world. But what we're talking about here is cell failure followed by chemical thermal runaway. Cells are also overpressure vented to prevent exploding but shit happens. By the way, insulation outside surface of box to...

    Battery explosions

    Drill batteries have an excellent history in the face off use/abuse. Chinese ebikes scooters and hover things do not. I lean towards putting the saw makers in the same quality rating as the hand tools, very good. That said, risk/damage is proportional to battery size and saw batteries are...
