    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...

    Anyone else have a browser malfunction after the buzz website changes last week? My older Safari froze. Been so long since I typed my password I forgot it and had to get it reset to switch browsers. Sorry if I stay logged in now but I'm uncomfortable with google taking control of any of my...

    EN Saddle Standards

    I'v found older presumably out of date copies of EN358 and EN364 (up to date versions are behind a paywall) and there is reference to a 1 m drop test. However, current sales info references 60 cm drop length. Yes this is in reference to work positioning saddle and not fall arrest...

    Cracked Ladder

    Have a few largish springtime cedar hedges (flowerbeds). Was up the 12' a frame then tugging the skinny legs to skid it over a foot. Snap. I'd noticed scuffing at the surface of the brace pivot before but chalked it up to wear. It contributed but wasn't the root cause. With this gangly...
