This is well over kill 2.5mm aluminium it's a bait tank for my boat, kind of a dicky location and shape but it allows me to run a hose straight up the back to feed water and i will drill holes thru the back of the tank for over flow, it will also have a lid and a small led light for night fishing

I will weld on some brackets to secure it once i weld it up, in no rush to finish it but if there is low wind tomorrow i might weld it up will be using the EWM mig won't be tig welding it due to this sheet of aluminium sitting out in the weather for 4+ years i will still prep it before welding, inside welded sections will get sikaflex if it leaks
