Got asked to bid a very unusual project

Only thing left to figure out is how to cut submerged logs quickly.

Ice fishermen use chainsaws to cut holes in the ice. Best practice is to use vegetable oil for the bar oil to avoid polluting the water.

Probably best to assume that the bar will never be good for anything else afterwards.

I think you're on the right track taking it apart with essentially hand tools. Sometimes the longest road is the shortest path.

Yep, and little dogs sit on the porch accomplishing nothing because they’re scared of “liability”, while big dogs get off the porch and get the jobs done.

So there’s that, too.

Look, I’m not going to go about this hastily and carelessly.
I’m making plans and calculating risks, checking insurance and consulting with the engineer.

I didn’t fall off the turnip truck yesterday, K?

I agree with your approach but also have you had an appropriate attorney advise you on all the possible liabilities that you are taking on?

Yep, blow it up while firewood size chunks of wood fly through those giant windows LOL

Easy! Just point the dynamite AWAY from the windows! Let me know if you need any further advice...

This is why they have to make equipment bigger ... to have room for all the safety stickers !
I'll stick with the Witch but I won't take her out on the lake !

Many years ago, my father hired a tree service to remove some huge oaks that fell into the lake on his property. It is an oxbow lake, about a mile long, but only 100 yards across, and the bank is too steep and 90' high, so no getting down there with any equipment other than chain saw. No way to get the logs up the hill.

There's a park across the lake from the property. The tree service somehow got the Army Corp of Engineers involved on "a training mission". They drove a 5 ton 6x6 truck into the park, used a rowboat to pull a rope across to the trees, then used the rope to pull cable from the 5 ton truck's winch across. Attached it to the large oak with twin trunks. The truck had no problems winching those two trunks across the lake, stumps and all. The only issue was they had to use an extension cable because there wasn't enough length on the winch. When they'd pulled in all of their cable, they just put the truck in reverse and backed up, pulling the trees the rest of the way across.

Just something to think about.

I would do exactly that, but here’s the difference on my project (IF it becomes my project).

1. Rivers have current. If you hook to a larger log and it breaks free, the current could drastically multiply the resistance pulling the log. That could be a disaster. You had the benefit of no current in a lake.
2. You also had the benefit of not having a log jam. When your logs were pulled across the lake, there was no risk of all of them breaking free and floating down a river, doing possible property damage.

I am still thinking wait until river is wadeable and cutting logs off a small piece at a time and letting them float away. Still has risk, but little overhead cost and smaller chance it all breaks free at once.
