    Neurodiversity thread

    One time I was helped by a guy was just a little something off, couldn't put my finger on it, no ask no tell. Pulling over a back leaning medium ash spar, I set up a static tie plus 2 or 4:1 pull/capture (can't remember exact config) and had a 1 1/4 wrap rope tail around the anchor trunk. My...

    Nerd Alert

    Copper Backing Welding Two stories are told. One is copper melts at a higher temperature and doesn't bond with the weld pool, partially due to it's heat sinking capability where it keeps itself cooler when contacting the weld pool.. The other story is if it gets hot enough the copper will...

    On a tree fell the flop always impresses, but the best message IMO is showing the careful skill at/during the cut like sighting the lay etc - ie the skill. Was there a shot of eg shaking hands/congratulating with a happy smiling satisfied customer? Would score points. Bit of counterpoint to...

    Be honest....

    Audio memory seems to stick in my head too. I do it for machining measurements eg "25 thou off" because they all mush into a blur after a while. "6 32" as you head to the tap set.

    Gas tank vent/jetting

    Plumbed up a crankcase pulse experiment today. First try duckbill filling an airtight about 750 ml brake bleeding jar - couldn't build any pressure. Sacrificed the long below-brake-fluid-surface tube to shorter (to keep the duckbill in open air) and decreased the air volume to about 200cc by...

    Avant/branch manager rotation troubleshooting

    I'd like to add a revision. Most DVM ammeter scales top out at 20A rms/dc and getting a higher capacity is a bit of a $$ unicorn in comparison. Enter the current shunt which is a low value resistor put in series with the current (just like the one inside a multimeter) but you can easily get a...

    Gas tank vent/jetting

    Other style - shorter, looks like hot plier squeezed tubing vs taped to tip - scored even slightly better. Little less than 1/4 psi to start and decayed to 0.1 psi ! I've got a big absolute gauge and I actually saw a difference in barometric pressure between test days. Weather's changing.

    Thinking back on n automotive vid chasing a draining battery the current probe could also serve for finding parasitic loads that stay on when you turn the key off and mysteriously drain your battery. Sometimes in a modern car it's a case of a failing module. $$$ at a mechanic

    Gas tank vent/jetting

    Tested the old duckbill back to back with one aftermarket, same geometry, probably different rubbers and clearly old vs new. Old (warm, bit of recent flexing) 3/4 psi FWD bleed down to 1/4 psi, new 1/4 psi FWD bleed down to 1/8 psi!! much better, just now to see if it survives gas/oil...

    Math is not the strong suit of disbelievers. You can flummox them into simpleton gibberish with a lot less than rocket science. Math is advanced quantitative reasoning - again not a strong suit. If you really want to cause a trigger try to eek out some Hawking vs Einstein fine points and...

    Do you ever have the occasional customer service experience like this?

    Some customers are just crappy and will even stiff you when you've done a whole bunch of add ons after the original quoted work Trick is trying spot them before and pre-fire them. No reasoning with them. If you did a second round of add ons they'd still probably grumble.

    Avant/branch manager rotation troubleshooting

    For fun if you've got a good multimeter a) capable of 30 or 40A current readings b) with peak detection, take a blown fuse and hotrod it into a pair of current leads to plug into your meter. Then sub it for the fuse and just read what load or spikes are occurring. Such a probe could pay back...

    Got some time to watch the shuttle vid. Excellent! IRIG-B, spooling up high speed film, HD takes me back. Film is a PITA! And you find out if you effed up a week later. Digital has far surpassed in performance now. Exposure and grainyness was the major problem. If you watch carefully you...

    Avant/branch manager rotation troubleshooting

    An electrical load is an electrical load, wherever you make/break the cct. Running/not running changes from battery terminal voltage to charge voltage so that can make about 10% difference in current load. Best to figure out why the fuse popped. Melted wires and switches are bad news and...

    Odd Plug Carbon

    Hypothesis Tank was bone empty when I dragged the unit out of winter storage. Seemed to rev more freely than it's consistent rich side sluggishness for all the years I've had it. I don't drain tanks for storage. Possible first year's occurrence of ethanol gas storage issue. YT vid said pure...

    Avant/branch manager rotation troubleshooting

    Is it new or used? Used, machine or attachment, internal wire fatigue breaks right at a connector can cause intermittent operation. Had such a wire on a car door power window motor. Manipulations during debug always seemed ok continuity but on reinstall the wire hung just right to trigger the...

    Odd Plug Carbon

    Ran the same machine again on the same fuel mix doing the same task - this time I didn't try to restart it. Exact same plug condition same spot on the porcelain except the black region was a relatively thin layer, smooth shiny black. I think it didn't orange peel because it wasn't exposed to a...
