Once welded I checked for any changes that might be needed.
Two things I didn't like was that at the 2 o'clock position, the arch is further out from the tyre compared to the other side. The other was that the front part of the arch could be tighter to follow the tyre and then end vertical, which is needed to bolt onto the running board. As shown earlier, I had already increased the radius in a couple of spots here as was even worse before.
I took a contour reading from the less damaged guard from the other side at the top centre. Placing the gauge at the same spot on this one showed the difference between them. If you rock the gauge back it would show how the front face is more vertical than the other side. Remember that this side was stretched out 50mm-2" more than that side too and was really hard to get into place in the wheel arch. I have already brought that back so it matches once installed, but could do with more in the relaxed state.
So with more time in the English Wheel, I now have matched the contour.
I have actually started to keep this contour right around the edge as it showed it was tightening up the arch radius when doing so. The light line shows some more still needs to be done toward the right side in the picture, so back in the English Wheel it goes.
What a difference that has made! Pulling up the edge with the new contour evened out the radius and it follows the tyre with better flow. Just a little more at the start to get it right for meeting the running board and it should be good to go.
Can see the transition needs some work which will solve the last problem.
Rear view I am happy with as well. Just a slight tidy up with the blend into the reverse curve to go.
