Ok now, i am moving towards a steel frame with ply/grp liner than a concrete block tank.
I have got a rough price...not cheap towards wood frame though, well obviousley hey

, about £150 more.
The idea is to U channel of either 3 x1.5 x 1/4 wall or the 4 x 2 x 1/4 wall, the larger will be around £100 more expensive, but a lot more strength.......but will that more strength be needed??
Maybe the top and bottom ring/frame could be of 4 x 2 and the rest 3 x 1.5?
The base could have the U channel going both ways as its easyer to weld in beteen the bearers than it is fit a good joint with wood.
The frame will have bearers spaced at 2` along the sides and bottom and an angle iron type window frame that will be laminated from the ply to give a good ultra strong frame...............
sorry just thinking and typing as i go the thoughts i have, i would put them in a diagram if i knew how to on this PC gadet

Well then, who think that the idea is a goer with a 4 x 2 top and bottom and the rest in 3 x 1.5, all 1/4 wall thick?
