I read the "I want to weld?now what" thread and it got me to thinking about a project I need to work on.
I'm restoring an old Victorian house. Back then there were several plumbing fixture manufactures but there were no standards. They all used there own thread sizes so you would have to come back to them for parts. I've bought some vintage faucets but none of the threads are ½ inch or ¾ inch or anything like that. My thought was to cut the threads off the old faucets and weld on threads from a modern faucet. I'm talking about the threads that are under the sink were the supply line screws on. Neither the threads or the weld will be visible above the sink.
The threaded part is roughly 3 inches long. The faucets are nickel plated brass. One is solid nickel. I'm wondering if the heat of the weld will tarnish or discolor the nickel plating. The weld would be about an inch and a half from the visible nickel plating.
Also, what would be the best way to weld brass. I have access to oxy-acetylene and an arc welder at work. I took welding in shop during high school so I have some experience but I am a novice. The welds will not have to support much at all.
Any thoughts?
