    Hi All,

    Can anyone please just check my design ;-)

    Cube: 800x800x700, water level 650

    sides: 10mm clear float glass, euro brace all around (40x12mm)
    bottom: (bit lost here).. 2x8mm, both floating inside.

    I tested this on about 5 glass calculators and sizes very from 8mm to 12mm on the glass thickness with 3.8 safety factor on them all, so really not sure which to believe.


    Thanks

    IMO if you can afford it go 12mm its safer and will give you peace of mind.
    I built mine 1mx1mx500mm 12mm and base 12mm + bottom bracing.

    12mm is obviously always better regarding strength,but yes you could get away with 10mm sides with good 10mm top and bottom bracing

    And a 16mm base for the bottom as you suggested(8mm +8mm) will suffice, especially considering the tank will be braced.

    Thanks guys,

    What will the minimum be to go braceless at the top?

    thanks

    Thanks... The price between the 10mm and 12mm is only about 20%, (R450 vs R 550/m2). So in grand scheme of things its nothing.

    Just know that rimless tanks and certain fish do not work out. Especially the jumpers. And any intertidal snail will climb out every day.

    Thanks,

    We prefer braced actually, always need shelf to put thing on......

    Also, if brace is flush to the top it always look neat as well.

    now to get the right dimensions for cutting :whistling:

    it is not a shelf
    its a brace

    Only thing allowed on a brace is an Auto Feeder

    Ok,

    had some design changes, after thinking measuring etc.

    new tank size, 800x800x630, water level ~600. (euro brace on the top edge and bottom corners ).

    Corner Overflow similar to this : d2mini's 130g Rimless Cube - Page 4 - Reef Central Online Community


    Does the following look correct?

    DT Tank
    Tank size: 800x800x630
    Cutting schedule:

    sides: 2off: 780x630 x 10mm
    front/back: 800x630 x 10mm
    bottom: 780x780 x 12mm. (floating)

    bracing: 4 off: 780mm x 40mm x 10mm, 4 off: 700mm x 40mm x 10mm

    Corner overlfow: still to be determined.

    Sump:
    800x800x350. (Stand will be 1000x1000x650mm, leaves ~280mm to get things in out of sump). Stand this low as tank will be viewed mostly while sitting.

    Cutting schedule:
    back/front: 800x350x6mm
    sides: 780x350x6mm.
    bottom:800x800x8mm

    Center baffle : 780x300x4mm
    other baffles, 320x300x4mm. Will cut to correct heights ones design done.

    Stand:
    1000x1000x650 (outside) (will leave 150mm at front and 1 side to act as a shelf. (don't ask))

    50mm x 2.5 square tubing. "Normal" structure with corner supports.

    Thanks in advance

    Hi

    I have just finished off my 800x800x650 and i am using 8mm float with top and bottom euro bracing and all is looking really well
    and doubled up on the base, so its a 16mm base

    Draw your design in Google Sketchup.

    Then you will know if it will work out.

    Way too early on a Monday morning to work out your tank. But it does seems that you do not have space for the silicone between the panes.

    Morning Riaan,

    Sketchup ... ish........I'm certified in CAD, but don't get sketchup:blush: but let me do some tuts.

    Theory is: sides are getting silicone on each joint so the inside will grow.... mmmm... but only in 1 dimension. . .:blush::blush: . .Ok, drawing board, here i come

    Riaan,
    One site said, 5 % of width and 1 size thicker. so 800mm x0.05 = 40mm x 12mm

    Here stand idea with sump. I did not do any "thinking" about strength, just rough layout.
