...and cut that sucker down, almost silently.
High pressure water cuts through 5" steel like butter, it
would
cut through wood like melted butter.
The loop gets wrapped around the tree and you pull it
closed as it cuts. You could also turn it so you only need
one nozzle.
Water cutting through wood.
https://www.youtube...watch?v=UF8uytY9jRw We're still using metal to cut wood why? [doctorremulac3, Nov 21 2017]
Good guess, new they go for about $300,000...
https://www.machine...-komatsu-pc220-lc-8 But beyond ten years old or so I'm seeing them as cheap as 1/10th that. Like cars I guess. [doctorremulac3, Nov 21 2017]

I wonder, though, how far away from the nozzle a water jet can cut - whenever I've seen them in use, the nozzle is very close to the substance being cut. |
|

It's almost touching. They're extremely precise so
maybe that's why it hasn't been suggested (as far as I
know) for doing something big and clunky like cutting
down a tree. |
|
|
Unlike a blade or cable, you wouldn't need to replace
any cutting surfaces except for the grit infused
water. |
|
|
As the cutting tube passes through the tree, it
could
distribute ball bearing spacers to keep the tree
from
collapsing on the cutting tube. These could be
squarish to keep the tree from falling until pushed
or
spherical to allow the tree to be "rolled" off of the
stump. |
|
|
Additionally, the grit and water mixture could be
sucked back by the tube for recycling further
reducing cost. |

See link to get an idea of how well water can cut
through wood. Yikes! |

Max, are you there? He's been taken up! |
|
|
Either that or I don't get the post. I'm guessing the
latter. |

Besides, if you were abducted by aliens you probably
wouldn't bother to type "...". |

I'm guessing that machine in the link, as incredibly
awesome as it is, costs... $300,000. Wild
guess. This would cost... six grand. Tops. |

And if it were configured properly it would be a lot
safer than a chainsaw. I've had experience with
those things. You need to know what you're doing
or you can wind up trimmed very quickly. |
