I want to mold my hoodbird into the hoodstrip, and can braze, but dont want to destroy a perfectly good hoodbird trying the impossible.
last time i put heat to pot metal screwin around for fun on a pitted to **** trunk emblem it turned into a puddle before i knew it haha!!! so i would say do some practice on sumthin else so you can get an idea for the heat.
The last time I had to weld on any pot metal (top bows for a 1950 Ford convertible) I used a Zinc rod and my tig. Unfortunately you can not get them any more (the zinc rods) that I know of but you might could make you some if you can find some zinc. They used to use them for galvanizing the welds on galvanized metal, this was years before they came up with a zinc based spray paint. But for welding your hood bird to your car I would try a Silicon Bronze rod with a Tig set up. This is how I used to weld ferous to non ferous metals together, flows great and you have a very nice finished weld.
Dont even consider these, I have welded for 30 plus years and have welded just about every kind of metal thats out there. A buddy asked me to come weld a crack on his 8BA block with some of those rods and I just about destroyed the damn thing. I had to go home and get the correct rod to fix the f@#K up.
i wonder if i could grind some off of a galvanized pipe, and make the dust into a rod in my buddys kiln.it would take a while to get enough to use, but i got more time than money.... anyone know the melting tempurature of zinc? his kiln goes to 1500 degrees. Or,are there any kind of plateable epoxys out there anyone knows of?
I was thinking more like using Zinc pellets that the platers use for cadmium plating. As far as the melting point I would think it would be close as to what silver soldier is because you could rub the rods on the welds after heating them up with a torch to galvanize them.
these guys are saying its hard, or impossible to find zinc rods. know where to get some? would save me alot of trouble.
Done this before with pot metal, works great and plates well.. just keep the heat low and work in small sections.
Be VERY careful ...zinc pot metal that is pitted can explode when it is heated...ask me how I know !!!!!
Which search engine did you try ?

oh no, i'll be using gas. i have no access, or experience with a tig welder. i have a mig, but i still prefer to braze in many situations. pops taught me to do it young, and i do it often at work changing refrigerator compressors the old ways wont die. at least not in my lifetime. i'd like to get, and learn tig, bu ill still always braze, soldier, and gas weld stuff

I was thinking of trying 'all metal' (think JB Weld with metal powder in it) to fill the pits, sand it smooth, and then powder coating it with the chrome-like powder. Would that work? (I can't see why not, but I've never tried it.)
