    Dremel Sharpening Bits

    Nothing great or special about this vid It shows a guy free-handing a sharpen with titanium coated diamond bit instead of the usual Oregon silicon carbide stones. My experience is oregon stones cut but wear down quickly changing diameter and -cylindricity(?)- I've seen welding fab guys go...

    Terrain Can Bite You

    I'm sure you've all seen some news coverage of the mountain peak/glacier tongue failure in China/Nepal that caused a debris flow compounding into a valley bottom river stream - inaccurately called a flash flood. I once innocently explored gravel and rock beds/slopes that were results of such...

    Sands of Time

    Got feeling nostalgic today so I thought I'd visit my grandparent's farm across the country away virtually on a google satellite view. Of course there's no address and it was before common folk could gps tag either. But I remembered, out of town on the highway, turn right at the grid road...

    Exhaust Bolts Seizing in Aluminum

    I've got a 30 year old 5 hp 4 stroke Briggs flathead. The muffler rotted out again. It uses about 1 1/2" 3/8" dia shoulder bolts with a 1/4-20 tip. One bolt broke free the other snapped/seized. Upon closer inspection the same bolt had seized/snapped last time too because I found a 4 quadrant...

    Odd Ways You've Seen a Tree Accessed

    First one goes back about 8 years. Young, wiry climber comes down mid-job and re-ascends grabbing the rigging line hand over hand and runs his legs up the trunk like the Batman TV show, one-strong-arm's it until he can get his lanyard onto the tree with his free hand. Don't recall if he had a...

    Tree Gear on Amazon

    Did a google to find the open-able Petzl ring and found multiple knockoffs with names I didn't recognise. All had graphics indicating CE EN approval - though we know how much that can mean in certain markets. Amazon served up related...

    Modern AI Tech

    Remember the good old days when telephone annoyance was - [ick up a call, say hello, wait and hear silence and just when you're about to hang up a machine which dialled to you switches you to a scripted (scam/telemarketer/survey) operator who wasted your time? After enough calls I developed the...

    Odd Plug Carbon

    I was picking away at small dead scruff all velcroed together today with a small 2t polesaw keeping the revs down to avoid kicks and entanglement. Turned the saw off for fuel and it wouldn't restart. Figured hot, maybe winter gas vapour lock, maybe grit in carb no fuel, it wouldn't fire...

    Gas tank vent/jetting

    I was just Sherlock Holmsing my friend's old Homelite. Cleaned the carb, new fuel line, fuel filter's good, impulse connections sound/sealed, carb kit. Tweaked the mixture screws all's good. On to the impulse pressure oiler. Remove some clogs, confirm rate valve, tight feed hose fit, but...

    Homelite Crankcase Pulse Chain Oiler

    I skipped these saws but my buddy has one. Looking up the carb came across this Rube Goldberg system. Crankcase pressure pulses drive oil pumping to the bar and chain. Infotainment. Enjoy!

    Welding and Chlorinated Cleaners PSA

    Quite a few folks on the buzz weld. I came across this quite educational video of how using chlorinated brake cleaner as a degreaser in weld prep can produce fatal phosgene gas that smells different but innocent and doesn't manifest problems till hours after exposure making it hard to...

    Tractoring a revver saw

    I think generally saw rpms have gone up through the years but a little voice tells me not to always run equipment at 100% because if it's going to wear out and break that's the most likely time for it to occur, However, I met a west coast guy who said he blew up his big saw by "dogging it in...

    Chain oil in the wind

    I was cutting some ugly firewood on the ground today. The wind came up occasionally and also changed directions. I touched my glasses and -smear-. Took a closer look and the whole lenses were peppered with oil microdots. Made me think about if I was also breathing those micro droplets...

    Stihl RS chain points

    RS is rapid super and has a squared cutting point (at the junction of the side cutting face and the top cutting face) as opposed to safer chains which round off that corner. I "rocked" a chain into hidden metal and it combo bent those points in/down and scraped off the sharpness of the cutting...
