    Howsit Guys,

    A freind has asked to help him design and execute a 2.5m X 900 X 700h, I have build tanks up to 2m but not at this width and height. We looking to do it in 12mm.

    Can the more experienced tank builders advise on the following.

    Single or double base, floating or bob (build on base)? Will 100 wide euro bracing be enough on this width or should we incorporate cross braces as well?
    @dallasg @leslie hempel @Nemeziz_za

    I can do a quick scetchup later.

    hi @Hammerhead

    I dont consider myself an expert on tank building but have build few tanks already for friends and including my own current tank so I have a little bit of experience I think... for your euro bracing I would suggest to always go with 10% of the width of the tank... in yoyr case that would be 25cm... if you double the bracing you could probably make it abit more narrow at about 20 cm... 10cm imo is not good enough... if you stick to the 10% of the width of the tank you will not need cross bracing..

    can you use 15mm glass.. I know the price difference is big but you pay for piece of mind.. even with 12mm tho I would go with a single base but make sure you brace it on the bottom as well with 25cm bracing and you can run two across as well.... I would build the tank on top of the base but only because im not familiar with tge other method of buiding iy around the base and dont know the benefits or the disadvantages if any...

    good luck and post some pics...

    I would build on base. 12mm should work. But as said, brace the base and the top. i would go euro brace 10% as said.

    having built my 2500x1000x600, 12mm was the limit for 600 high, at 700 i personally wouldnt take the chance
    i would have eurobracing and 2 cross braces at 10cm wide, and a base made from 2-3 layers of 10mm or 12mm

    i like to sleep at night :)

    with those dimensions you get a safety of 2.4 for the sides and 1.4 for the base

    if you go 20-30mm base made from 10mm you get 4 or 9 rating
    as for sides to get a safety of 3.8 or more you need 15mm or 24mm laminate...

    you looking at a tank around 2 tons filled etc either drop to 600 or go thicker glass

    12mm will be fine for the size proposed.

    i would suggest properly bracing the base and allround bracing including width ways top and bottim, if you want to go euro brace you would then need to look at 15mm or thicker for the structure.

    i am building a simular size and will be using 12mm based on the build description above.

    Width is 900, length is 2.5. 10% of width will be 90mm.

    Always use double interlocked euro on all builds.

    Never under stood how the numerical scale worked on safety factor. Does 2.4 mean its 2.4 time stronger than it should be? What is the preferred safety rating? Can you explain how this works.

    Would you suggest BOB or Floating considering the bottom bracing will be joined to the front panel? At this length?

    Let me see if I got this!

    If I use 12mm @700 High I will do double euro bracing as well as cross bracing. What would the width of these braces be, 250mm will surely cut out too much light (LED).

    If I use 15mm @700 High I can do double euro bracing without cross bracing. What will the optimum width of these braces be?

    Sorry for all the questions? And thanks for taking the time to respond, really appreciate all inputs.

    Make use of floating base... and don't build the sides on the base let it be next to the base with a 3mm seam...

    Single or double base or just bottom bracing. Should the Front and sides also have 3mm spacing or butt joined?

    I will do a sketchup of it once I get the nitty gritty out the way.

    ok perfect. Will post a sketchup shortly. Any particular reason we don't use toughened glass apart from the cost factor?

    i am going to build mine on the base base glass with 50mm wide braces doubled.. the top braces on mine will be 100mm

    i personally only go to float base when the glass used for the structural construction is thicker than 15mm and contributes greatly to the pressure exherted on the base..

    it cant hurt to go float base though...

    now duplicate the top bracing design and change the width of the glass braces to either 50mm or 80mm..

    thats how id do it... wider than 80mm and your just wasting glue.

    sorry @Hammerhead. .. I ment to say 10% of the lenght... which will give you 25cm.. if you double the brace you could do with less like 20cm for example.. if you stick to the 10% rule I dont think you would need the cross braces on top..

    I shouldnt post at 1 in the morning :p
