I need to saw a tree in Dumfries in front of the rowing club in waist depth water with a two man cross cut, would it be possible to borrow such a saw? It will get wet!

The above from a friend who wants to borrow a saw. I think I need to give him one with a lot of set because of waterlogged timber. I have one at 40 thou.

I've cut a submerged log with a normal saw with normal set, about 0.012". It cut fine and the water make a good lubricant. If the log is saturated it should be swelled as large as it is going to get and should not swell any more because it is cut.

Several years ago there was a project to clear a water trail with crosscuts. Juniper Springs Canoe Run

The saws we used at Congaree NP to cut in the swamp were initially set at 12 thou. We saw a lot of bind in the cuts so I widened the set to 20 for a crescent ground saw and 25 for flat saws. Didn't seem to have any more problems.
