G'Day,
As a after though,when I had bought all the material, I was thinking that I should have bought a Water Tank,a plastic one about 2.1 mt across and about 2.4 high, was $1100 incl shipping anywhere from W'Gong to Newcastle,then all you had to do was to cut the floor out,cut out a door,cut out a slit for the roof.You can get them in white and off white and will never leak,and with the floor that you just cut out,just cut a hold in the middle the width of your pier,slip it over the pier and Bob's your Uncle,so much easier and quicker and no hassle, with a few heavy duty casters on the bottom and thats it,put it on concrete or a wooden platform.BTW is does not have to be plastic,tin would be just as good, but would need a little more work than the plastic one's
Cheers
Arthur
