    Debarking logs with a pressure washer - GIF

    What's going on here? Unusually powerful pressure washer? Only works on a specific species of wood? Logs have been prepped somehow?



    Regardless, this reminds me that I remain in search of a long German word that means, roughly translated:

    "When you are happy to see a new way to do something, but also saddened by the realization that you have spent many years doing it the wrong way."

    Weltschmerz? Not quite what you want but it covers a lot of territory as many German words do.

    At about .27 with the barn in the background there is a tree, apple?, in the top rt corner which looks to be in bloom. Most trees have a window of time early in the growing season when the cambium of the bark is especially weak and bark pealing is very easy. On a Hophornbeam tree (some call it iron wood) bark can be pulled in strips 12' or more up a standing tree, peal then cut down is some times easier. My boss and i try to hit this window when we harvest trees for rustic railings, ect. My guess is these trees were cut at the peak of this window for their species. Bark comes off easy but no noticable damage to the wood underneath. As some may have experienced high pressure water in too concentrated a streem will gouge wood badly. I would have to say operator is using a tip of greater than 20 deg. My 3600 psi washer with a 15 deg. tip can chew up wood real easy. When i built my log cabin i draw knifed all the logs and dreamed of removing bark this easily. Come spring I hope to get to try this. Fast n great results.

    On second look the tip appears to be a turbo tip. Zero deg that spins in about a 15 deg cone, making circles. Either the psi is turned down or a large orfice. I bought a turbo tip for my pressure washer as I thought it would be great. Turned out to have a very small orfice that can do much damage. Destroyed the radiator in our 1950 John Deere M. Never thought about the radiator being thin as it is thermo-syphon system and not pressurized. Lesson learned, the hard way. Thanks for the post

    "Welt" is the German word for "world". German for "write" is "schreiben", nowhere close to "Welt".

    looks like slash pine from forestry for housing frames etc. Guess that is somewhat more powerful than my old (now discarded) 240v 2350psi Karcher. May be a Lato.

    Like to see them try that with Eucalyptus siderloxon.or a smaller tree= Sarcopteryx stipata. In Qld , we also have another tree here that pioneers called "break axe" for obvious reasons but can't remember its botanical name at the moment. The Spanish have a similar common name for one of theirs.

    I've seen iron bark that the white ants ate out the centre totally but left all bark whereas they usually only leave a paper thin membrane to protect them from sunlight & preditors( wont stop echidnas though).

    Those are White Pine logs and he's using a 3000+psi pressure washer. The key is to keep the wand moving so as not to damage the wood underneath. Works really good on the different pines, and spruces. I imagine it'd work really well on the invasive Salt Cedars, and big Mesquite trees that we have here in Arizona as well.
