I spent Saturday and Sunday correcting the error in the alignment of frame 4.

If you look very closely at the first picture below you might just make out a devation in the door sill for the second last frame.

To correct this I had to:

• Remove the two rows of cladding around frame 4
• Remove the starter rail on both sides of the frame
• Unstaple the flashing on either side of the frame
• Unfix the frame from the rough opening
• Chisel out some more of the frame so that it could be positioned more in to the rough opening
• Redo all the steps listed above

This took all of Saturday and most of Sunday - so a whole week has gone by to get back to zero.
