So I picked up this pair of sidelights with the intention to make one good taillight for my speedster out of the two (one is missing multiple pieces). The brass is considerably dented and has some cracks. Is gas welding with brazing rod a viable option?
I like silver brazing using "handy flux".
Heat the brass to a dull red and quench in water prior to ANY straightening work. And don't be afraid to re-anneal often!!
But you probably know all this!!
Oh and I forgot to mention there is an electric plug in the bottom leaving about a 5/8" hole.
Brass can be welded but it is a skill few possess. The solder Les mentions is not as strong but is much easier.
So this would be a skill that I should try to attain then.
It looks like your light was manufactured in about the 1913-14 era when they were transitioning from kerosene to electric. The light could have originally been made to burn kerosene or have an electric bulb.
Les pretty much hit the nail on the head as to what to do with it. I use the silver brazing like he talks about. My rod is 45% silver. Unlike regular brazing rod, it has a "wicking" action. With silver braze you can apply the silver braze from the inside and it will flow to the outside, filling the cracks as it goes. Once you try it, you will find all kinds of uses for it. It is a slightly different color than brass but it's pretty hard to tell if you keep it polished. I get mine at a local welding supply. Roughly 10 cents an inch.
