I had tried welding the first one last week.

It looked a little untidy so I spent a few minutes grinding back the ugly edges.

I then went to work on the next three - this took me the whole day.

Each screw pile needed to be plated over wherever a hole interfered with welding down the column walls.

I had to cut out all sorts of shape from some scrap plating.

Also, my first attempt at welding 4 mm wall to 10 mm screw pile resulted in punching holes through the metal.

Subsequently I reduced the current right down to 80 amps.

This meant that I needed to lay down 4 tracks for each weld and ended up with some very time consuming work.

I still have 3 columns to go and helpfully I can knock these over next week.

Tuesday

I was becoming concerned about forcast rain and its effect on the rust converted surfaces.

I nipped out to site at 5.00 pm and applied a coating of zinc primer to the inside surface of the front PFC.

I'm hoping to get out another day during the week and complete the other faces.
