On the coast where the storm surge came in and then quickly went back out a lot of stuff was saved.But it was still saltwater and saltwater trashes everything quick especially motors.
Most of the stuff our customers at work saved were woodworking machines.New motors and bearings and they are good.
The machine shop stuff didn't fair to well,the older stuff that probably wouldn't be hurt much mostly went for scrap,too much cost to re-build.
I know of two pieces of CNC that flooded and were saved,took major effort though.
The stuff in NOLA was almost a total loss,that water came in and sat for months.
I know of one steel wall plant in Chalmette,La that was less than a one year old when it got flooded.Total loss and all of that stuff was new and $$$$$$$.
If a person has small tools they could be loaded and hauled to high ground.Other than that the best tactic I have heard was posted here.
Jack the machine up,slip a couple sheets of heavy mill plastic sheet under the machine,then bring the plastic over top and tie it all up like a trash bag.
Might work,assuming nothing sharp was left to tear holes in the bag.
I just need one more tool,just one!
