Preparing the floor

The first I did today was the clean up of the transmission support.
This first picture is before.

 And this is after the clean up.

 Here the rail is mounted in place and fully welded.

 The welds are mad outside and on the inside to make a strong connection.

 Then  I started preparing the floor. The paint is removed in the places where there will be welded.

 Next I started drilling holes in the parts where the floor is resting on the frame.
