The drums have been away for welding over the last week or so (the welder was away mid way hence the time it took..) He has welded along the seam and around the edge of the drums to attach the cones to what will become th ebottom of the tanks:
On the top (bottom of the tank) there is a threaded pipe fitting t allowe the pipe work to attach. This too is welded in place.
Lastly, I the welder has attacjed three box sections of steel to the sides of the tanks. Into these go the support legs to raise the tanks off the ground. Once in place the taks stand a little under 6 feet tall.
