When I cut the plate to size, do I leave a gap for the weld, or leave it flush with the edge of the bumper channel?
Thanks murphy98
Looking really good WhippinSaw! I can understand the trouble getting the gap right at the fender, hard to do a compound curve at the tip on thick material like that. I wonder if the original tips were done on some kind of stamping machine for consistency? I did leave the diamond plate set back from the edge of the bumper about 1/16" to allow room for the weld bead. Then I used a grinder to round over the edge & smooth out the welds to match the original continuous weld bead on the rest of the bumper.
You're doing a fantastic job, keep up the great work it will pay off when you're all done and ready for paint.
