Un-leveled tank

I am also in the un-level tank club! woohoo! We need t-shirts. My tank was level when I started and the stand is still level so ya, the foam did not compress evenly I guess. Has been like this for a couple of years now. Off by about half a centimeter to a centimeter as well.

Glad I am not the only one... And yes we need t-shirts, so Lastlight get on it! I would buy one for sure.

Grizz, I like your idea of the leveling screws, but I do think having my stand with 100% contact on the floor is the best, so I can live with the slight slant. Not sure about the wieght/pressure on those screws, but again I am not a master welder like you

I'd be more worried about the floor/stand/tank being flat. If the stand is contorted, it will stress the seams. I've had a small tank burst because the stand wasn't flat.

I couldn't say either way how important it is for the stand to be level, but the other posters probably have it right.

just for you buddy.

I use 3/4" A325 Type 1 structural bolts. The allowable shear strength in single shear is 7500 lbs for a slip critical connection. In double shear its 15000 lbs. This goes up if you choose to do a bearing type connection. For the application I use them in the threads will withstand 1000 lbs per bolt, so for example my 8'er has 10 screw legs each withstanding 1000 lbs totaling 10k lbs. Then I weld a 1/4" x 4" round plate to distribute some more of the down force.

HEHE, now I look like a deer in headlights. Eyes just glazed over, with a numbness falling over me.

I guess it pays to know your shiet! This is why the rest of us have to look at our tanks with our heads slightly cocked.

I am like Griz, I had six 1" leveling screws on my stand I made which bottomed out on a 10"x8" pad to spread out the weight on the floor.

I realy don't think you will have to much of a problem but I have heard of a couple tanks in the last 13 years that have let loose and they figure it was from not being level. for me personaly 5mm is not much, its more of a cosmetic thing that would bother me.

6' not level.
Used to be when first set up, now it is about 1/2" off on one side. Drives me nuts knowing that, but can't do nothing about it. Been like this for 4 years now.**fingers and toes crossed**
