Fixing cast metal grill

I've been gathering the pieces to put together '40 Ford standard grill. While both side pieces are complete, there are a few cracked 'teeth'. I know straight welding isn't recomended so how would I go about fixing them without destroying them? I'm not looking to have a perfect grill just solid, strong and relativley decent looking. Thanks for taking the time to read this. -stick

 

silicone bronze rod with a tig. i have'nt had the fun experience of doing it but that is what a buddy used. damn stuff sticks to everything!

 

I'll second the silicon Bronze rod. Thats what I would try first.

 

I don't have tig. Can I use a oxy/acetylene torch? And if so any tip/flame recommendations? Thanks -stick

 

Anyone? Is brazing an option? Thanks all. -stick

Brazing it should work,shouldn't it?

 

I wouldn't bank on it,but wouldn't JB weld work? it adheres to a good sanded surface and its sandable.Never tried it,but I've used it in more extreme conditions than a grill with good results.

 

Is it made of pot metal? I haven't tried this product yet, but take a look at these guys. They have a fairly convincing video of it in action:

Hey Stick,

I'd stay away from brazing given the heat range on old pot metal.

There use to be welding rod, for the repair of Zamac/pot metal
castings, but I haven't seen any for over thirty years. "Maybe''
some of those "swapmeet welding rods'' would work, but I don't
have any experance with them.
You can solder (lead) the repairs, and add steel cleats for strength
purposes. I'd go with a 50/50 type, proper flux and clean metal.

I repaired a snapped in half hood handle base on my 39 ford pickup. This part is made of diecast muck metal. I used a locally obtained welding/soldering rod that can be used with a gas welder or even just a blow torch. All you do is wire brush the repair area with a stainless brush and weld away! It work great for me. It's very simple to use and works well.
You could email the company and see if they have an outlet in the US or just buy the stuff on line.[FONT=Arial, Helvetica, Verdana] www.durafix.co.nz[/FONT]
