    Hi Guys, is there a thread on Masa somewhere that has a formula to work out what size square tubing needs to be used to support a specific tank size/weight?
    Or if one of you guys know it perhaps? :p

    Thanx :wave2:

    I'm still planning it. Don't want to go too big like a 6 or 8 foot, was thinking of a 1300L x 800W x 600H with a full width(800) overflow and have the 2 1300 sides and the 1 800 side for viewing. One of the small sides will be against the wall. The reason for 1300 is 100mm will be for the overflow so I won't loose water volume and for the standard 4 foot (1200) tank that I wanna use as a sump. Should fit nicely underneath. Still thinking about it though...;)

    Must have posted 2gether, a 1300L x 800W x 600H. Also at the bottom of the frame will be a 4 foot sump and all the equipment.

    dont rush yourself, take it easy and plan yourself well, ive been planning
    my tank for month and its taking shape slowly, ive been to my LFS and seen the stands they have and it is the same size as my tubes, tell me how will you cut your tubes? with a saw or a grinding disc?

    SPOT on Leslie 38 x38 mm square tubing is more than strong enough,just remember to weld cross braces in as well for more support and stability A 4 AWAY

    I will use at least 38 x 38 then. Thanks guys. I got a cut-off grinder to cut 90deg and 45deg for the corners ;)
    I'm not in any hurry, will plan this one thoroughly. I want to make it safe, user friendly and get the best equipment I can afford for it, even if it takes me 2 years.

    I will take pics of all progress and post when I set everything up - could be a few months or so. I know how you guys like pics :whistling:

    PS: Not moving to JHB for now, decided to stay. Wanted another tank anyway, so the selling of my previous one was not in vain :)

    Watch this space!!!!!!!!!!! :1:

    Don't be shy with the thickness. Rather too much than too little

    Wouldn't an angle iron frame be better? It is cheaper than square tubing I think. Heard that in time square tubing rusts from the inside. It won't look that bad if it's painted and it's going to be covered anyway. What you guys think?
