Hi, tremendous build. What thickness ply did you use and how high do you think you could take a structure like this before water pressure becomes an issue?
9mm plywood. There is a tremendous amount of strength in the bottoms. The base is actually wrapped up onto the side. If you were to use sufficient bracing I don't think you would have any issues going 4 or 5 feet perhaps even more. It's all about the bracing and the fibreglass just adds so much extra strength to it all. Obviously if you do very long spans then you could up number of braces and use more substantial timber. You could also create a structure like this with a liner but the fibreglass adds a lot to the strength. Most of the pressure is in the bottom half of the tank so that's were a failure would likely to happen first.
@@leecalladine Great answer Lee. Thanks for taking the time. I actually bought some 4 by 1 today. I want to make a freestanding movable tank. I'm just worried whether it'll be strong enough at 4 feet deep. I hope to fibreglass but won't have concrete to add strength at the base. Do your videos show your bracing techniques? looking forward to the next installment!
@@leecalladine Ah. So by bracing you mean the layers of 4 by 1 timber, rather than the use of metal strapping or anything? I'm thinking of doing 5 layers of 4 by 1 up to a height of just over 4 feet. Thanks Lee!

Good Work Lee,Well done Mate
Thanks. Still working hard in it new video out next week.
great video lee
Thanks hopefully getting an update out in a day or so.
Thanks for filming Lee look forward to the rest of the build
Thank you. Working on the project right now things are really taking shape.
Amazing vid Lee 👍im tired just watching as its a big job but it'll be well worth it. Keep up the good work mate
Thanks. Its getting there. Pipework pumps and all sorts to come.

@@user-nw6wl7py8k if you look at the earlier video I did on this system I showed the bracing being put up.

How much would it cost approximately to fibreglass a pond roughly the size of one of the smaller quarantine ponds lee?
