I'm wondering what thickness material to use on my project. I don't want it to thin. Maybe 1/4" plate?
3/64ths sounds really thin. That's .047. That's 18 gauge sheet metal. I can't see how having it to thick would hurt.
I replied to this a while back, and it seemed to just go out into the ether and disappear..... So anyway, here goes again.
I think that if using sheet metal, you'd want to use as thick a sheet as possible. I think that if I were doing one, I'd want to do a double thickness, so that what hits the bottom doesn't show up on top.
Triple plating chrome top and bottom would also add to strength and prevent twisting and rippling; eh, wawusit? ;-)
Another thing I was thinking was to drill holes at the bumper brackets and use J-bolts with acorn nuts or bumper bolts with brackets to hold it tight against them. I just really hate rattles and search them out and do what's necessary to stop them!
