Really enjoyed this week as was good to see it taking more shape.
Time to try out the upper part of the wall to make sure they are exactly at the same height as each other. Had to take 2 millimeters out of the right side to get it sitting perfectly level across the top of the window.
Strangely both sides of the lower part of the window angled up in the middle? To get it parallel with the top, I shrunk both sides at the corner of the bottom edge to pull it down. Then had to retrim the bottom edge.
I have the level hard against the edge of the door to make sure the door opening stays square to the door pillar. The back of the door is perfectly straight so can do this.
Tacked and ready to grind down the tack welds flush, inside and out, so I can run over them as I tig weld. If I don't do that I can feel the hard spots left during planishing, leaving uneven stretch.
The tig weld pulled hard when shrinking during cooling, but easily fixed by plashing to stretch the weld back out again.
Had a section marked in chalk where it was still pulled in a bit.
Hammering from the inside out against this steel block got all but a section above the weld area flush.
Used the shrinking disc on the inside along with compressed air to cool it to push the low spot outwards.
Nice and flat right across now.
As I was tacking the other side, this end lifted even after plashing the tacks as I went along. So stopped to rectify it.
Fully tig welded the section tacked and then planished only the area around the side to raise that part which brought this end down back to perfect.
