Update from today's effort.
Started by sanding off most of the power coat so I was sure to get everything flush and square when fitting the side pieces.
Once I had finally settled on the angle I wanted, the fun was getting it tacked exactly flush and at the right height and angle. As this angle is less then what was before I have the fun of cutting little wedges to fill in the gaps.
I fully weld it by either leaving around a 2 mm gap or running the cut off wheel down it to get full penetration. Even though the weld comes through to the other side, I still place a cover weld over the join on the inside which is not ground back like the front face to give added strength ( will be stronger at the weld than the surrounding metal ).
It is not just the top that needs doing as I have had to add the wedges underneath as well. Here it shows one piece welded in and ground back before the next piece is added above it.
The top piece added and then the final weld to the joining plate put down.
Here you can see the test fit and the final angle finished for that join only. The corner will be the next altered as it will be pulled across tighter and the bar slid across so more protection is given around the side while still ending up flush with the flare.
Here you can see too how much has to be cut from the overall length as goes much further along the grille than the nearly finished side.
