welding bumpers

Hey, I just got another set of bumpers for my ghia. From a 71' with over-riders. They are in good shape metal wise, no rot, all the brackets are good. I have them disassembeld and want to weld up the holes where the over-rider end pieces go in, to make euro like bumpers. What technique should I use? weld a small piece of metal in, or fill it with the rod? and how do I ensure it is dead smooth before finishing it.

The chrome is really bad i.e. is peeling and pitted. What do I use to strip all the old chrome off, without grinding it? I would like to do as much of the work as I can before taking them to be re-chromed.

Take them to the chrome shop and have them dechromed. When the old chrome is gone, do your thing (welding, filling, grinding, smoothing, polishing etc). After that, just take them back to the shop to be finished - chrome plated.

As Misha said, the chrome needs to be removed first. A reverse electro-plating process is used. Cheap chrome shops just grind it off.

How much will chroming co$t? I know it depends where I go etc but roughly? I will probably have to go to a bigger city to find someone who does it.

I would see if the plater will fill the holes. Most good chrome shops are set up to do repairs like filling those. The trouble is that the platers love to blame others for problems. If someone else does the welding and there is a flaw in the plating they will say its the welder's fault. If they do the repair then they don't have an excuse if it doesn't turn out right.

But then again, platers ruin their share of parts and just shrug it off. You're better off bringing a "finished to your satisfaction" piece to the platers than trusting them to fix it right. Whatever the guy at the counter tells you, the grinder guy doesn't know anything about.
