I will be off Thur/Fri/Sat. Hope to get the bottom skirt cut and tack welded for a more finished look. The I can pull the whole thing off and weld it all up.
This is a lot of work. Now I understand why shops charge so much for these bumpers!

I can always come back and put the skirt on if I want later. I would have to repaint the whole thing though. Decisions decisions....

Are you talking about the top of the bumper that matches the contour of the grill and headlights?
I think that is what you are talking about. I made marks on it where I wanted the bumper to angle back and notched it out. Then on the front I scored a line with my grinder cutting blade about halfway through the metal. Once I had the notches cut and the front scored I was able to bend the ends to the angle needed to match the contour of the grill/headlight assembly.
After I got it fitted right, I pulled it off and welded the top and front then cleaned it up with the grinder. I should have taken pictures of that part of the process. I was just too excited to get it done and see what is was going to look like.

what was the initial length you cut it to before you bent the pieces in? I am going to pick up a piece of angle on my way home to do this same bumper.

so number 1 is what i think you said and number 2 is what would probably be better. see how when it bends it stretches the thinner part of the metal is all there is? i know you said you welded over it, i just think having the metal butt up against itself is better. if you do a contoured reinforcement just bend it regularly (vise and a bfh!) drill the holes first if you are going to rosette weld it.
damn I need a welder haha then i can put my welds where my mouth is and more metal where my rig is...

Good looking bumper, nice work. Jerry has a point but you can add strength by welding in a gusset on the back side at the bends and should be strong enough.
