Debarking logs with a pressure washer - GIF

[suther51]

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
