Steven,
Sorry I didn't notice this post until now or I would've offered some help this weekend.
Anyway, I didn't really have the time to read every reply, but I get a little water is my basement occasionally and here are some things you can do depending on how deep the water gets . . .
- Buy yourself a pack of heavy Solo disposable cups. Put each leg inside a cup on the floor. This will help up to 3 inches or so and keep your levelers from rusting.
- Get yourself something to sit unassembled machines on. I install fencing, so I cut up aluminum posts to short lengths to raise things off the floor. Don't use wood, it'll just wick the water up to the machines. If you need some aluminum props, let me know. You can come over and we'll make some for you.
- Get a dehumidifier ( it looks like you did ) and keep it running.
Just a few suggestions until you can find a more permanant solution.
Good luck,
G

Getting on or off the floor once the back legs are off is the worst part for me. At least you're not dealing with a STTNG or TZ, those are nightmares!

That part I can usually handle with my lower leg. What about getting it from the on the stool/sawhorse level to the on the floor level. With those widebodys especially, I run the risk of throwing my back out and pinching the ends of my fingers off. Any tricks for that? Of course 2 people would be the ideal answer, but I don't trust my wife not to drop her side and any friends I do have scatter when I need a favor. Lol

Yeah, my friends are a buncha dicks, they show up when they need something though. Wish I had some friends in the same hobby.
