    OLDS-Overhead Lowering...

    There's always the fab/refurb option. You don't have to be exact in part replication, just adequate for the purpose.

    Rope grab recommendations for rigging

    I see the continuum as worst concentrated force load on small heavy concentrations toothed devices, not as bad concentration on more pointed small radius contact cams/pinches, then longer/gentler smooth face cammed contact, and best the full rope surface spread of friction hitch contact. By...

    Mysterious echo2511t issue

    The secret to using an impact is the apparent instantaneous immovability of the inertia of the crankshaft and flywheel during the hammering impulses. If you tried to impact-undo a stuck nut-bolt combo in free air it wouldn't work because the bolt has very little inertia. So you've got to have...

    Rope grab recommendations for rigging

    Is there any compendium or chart of cordage plus rope combos slippage force for common hitch knots? I'm pretty sure there have been dribs and drabs of selected combinations in vids by enthusiastic pull testers through the years IIRC.

    Possible damage from impact of felling a large tree close to a house.

    At a property destined for demolition and rebuild, I dropped a medium big maple spar onto a double layered asphalt driveway (resurface onto original layer). A stub punched a clean fair sized hole cleanly and deep enough I couldn't see evidence of where the asphalt and sub-base went except that...

    Songs of Perfection

    Story. Back when there were record stores in the early 90's I came across a ridiculous album that my friend said I would listen to once and never again. He was mostly right. The band apparently got reincarnated. Twang, my earlier C+W catchall is not the appropriate word for this one. I...

    Is cat rescue tree work?

    Sometimes you have to bridge the local inter-neighbour politics which can take some PR skill and effort, I agree. Good work. Nice to see a good ole VT not-fat-guy knot. Once I fixed a tree mounted yard light, quite trivial, but carrying up and using tools aloft impressed the hell out of the...

    Total cool nerd alert. For others this never happened and can't happen.

    New device from ISC

    The UK guy got more slippage if he put tension on the rope's tail. Figured it might affect the rope pinch at the bottom. He's got a new vid, two replacement units from ISC and different rope.

    Using canola oil for bar lube - oiling issues now. Never in the past

    Curiosity google - alcohol does diddly dissolving canola oil, apparently hexane is used to extract it from the seed mush. I have a faint recollection that hexane may be one of the many anes and enes in the formulation for gas. So gas may dissolve it if you get a gel blockage. Maybe. edit -...

    Using canola oil for bar lube - oiling issues now. Never in the past

    For you chemistry guys - is the canola oil molecule similar (like dissolves like) to petroleum molecules so shock treatment with premix or atf would actually do dissolving? Or would it need the alcohol-like family of solvents? I know seemingly invincible solvents do diddly squat if the target...

    Bark receding about 1' up around entire base of silver maple

    Look for marks on the white wood for signs of saw cut. knife cut or gnawing. Once a customer played coy with me pretending the girdling saw cuts weren't there till I saw them. Then they admitted to it. There could be girdling marks just behind the bark edge if the tree tried one hurrah at...

    Mysterious echo2511t issue

    Using stuffed rope get the piston about half way to tdc before you stuff the rope in so it doesn't work its way into the ports and get sheared off there when you apply torque to the clutch. If you use an impact or normal wrench be cognisant of whether you're applying load to the pull start cord...

    Songs of Perfection

    Story. The turkey song got me on a country (and western! both kinds!) jag and I came across Dave Dudley's 6 days on the road. Back in the day just out of high school I was in a C+W band and was instructed that at this particular bar Dave would be coming up to play my guitar for this song...

    TCIA WTF?

    Odd, the comment about Mark being active on other forum alternatives. I figured he was just pulling a recluse. I have periodically considered the fact that he was absent. His right/decision to choose. edit - I gave equal weight to treebuzz and treehouse until treehouse changed up its...

    Mysterious echo2511t issue

    If I were you I'd pull off the other two springs and inspect for wear/thinning right where they contact/hook onto the clutch. I've often seen thinning/wear at that point on various equipment. The other two might be close to failure too. $ for another cover(?) At some point the clutch shoe...

    Wtb mini porti

    A technical thought. IIt is known that knot tightening or settling is a method or means that absorbs and lowers the peak spike of a shock load, including half hitches grabbing a spar log. So in that case the X crossing is rope on rope and a potential (actually seems more like a certainty to...

    Bearing replacement question

    Situation looks much better, seeing the bearings on the outside structure face. Looks like a candidate for belts/pulley off, prep shaft, pull bearing. You don't have to be gentle on a bearing you're throwing away. Vernier works good for finding dia high spots. Also gentle sliding the new...
