Leveling top of tank stand

[oneeyedfrog]

We built a timber stand for my 4'x 2'x 2'.

Coz I had to have it where I wanted it :lol: - along the joists that have the biggest span in the house -we had get our engineer friend in to advise.

We had to reinforce the floor and build the tank stand so it sat perfectly along two joists . For some reason the joists there were closer together than elsewhere so the bottom of the tank is about 4cms wider than the stand. So we built a top of 2x6 laid flat.

Problem is it's not perfectly flat. The base of the stand is level its just uneveness between each plank of 2x6.

Any ideas on how to best remedy this?

I think trying to sand or plane it would be harder than it sounds.

Could I just put a layer of ply on top? How thick would it have to be?

I have read that putting a layer of liquid nails then a sheet of ply on top and then putting the tank on top will level it out. Anyone done this?

Thanks

Yep, I did it with an uneven steel stand and it works, but I think using poly would be easier.

Depends on how uneven it is. If its just a mil or 2 the poly would be fine. If it is more them thick poly or planing might be required.

Had a go with a belt sander today. I thought I might end up taking too much but it was ok.

Got hubby to help put the tank on and I can slip a bit of paper under some bits. Should be ok as it's less than 1mm.

Yeah, as long as you're still putting it on on some eps you'll be fine.
