Thanks

Troy,
Could you please be more specific with you question?

When I think of alloy, I immediately assume you're talking about aluminum.

It won't rust.

Your bonnet will be as strong as you want it, according to how you build it.

I'm not sure of the designation for alloys in Australia, but in the States, we normally use 3003 H14 .063

To clarify:
3003 is the alloy
H14 is the hardness rating, which in this case is half hard.
.063 is the thickness, of course

With this material, it's not necessary to anneal. In fact, I wouldn't suggest it, as it will make too soft for automotive panel work, which will result in a panel that dents very easily. You would only anneal it in an area where there is deep drawing and the material needs to stretch a substantial amount. Even at that, you would only spot anneal it.

If you could post pictures of what you're working on, that would be super!!

Hey Randy Ferguson.
Thanks for the advice man! As of right now I'm working on a design. It will basically be a different car, I'm just looking for a car that has what I want. SO I can build off of it, so to speak lol! Yeah sorry when I say alloy I mean ALuminium! Oh and just a quick question, what does anneal it mean? have a good one man! Thanks for your reply!
Thanks
Troy

Hi Troy,

Anneal means to soften by heating to a certain temperature and either water or air quenching.

A couple easy ways to go about it are to mark the panel with a wide tip permanent marker, in a grid pattern with the marks about 1"-1.5" apart. You then use either an O/A torch or a propane weed burner to heat the panel to point of burning off the ink. Don't heat it beyond that or it may melt, ruining your panel. The other way is to use the O/A torch with an acetylene rich flame to apply a layer of soot to the panel, then by turning up the oxygen or using the weed burner, burn the soot off. Again, don't go any hotter than it takes for the soot to burn off or you'll have a pile of molton aluminum on the floor!!

As previously mentioned, I wouldn't suggest annealing unless it's absolutely necessary.

I'd love to see what you have in mind.

How are you going about designing what you want??

I normally build a quick buck from 1/4" hot roll rod to get an idea of how the finished product will look.

Hi Troy,

Scratch building, eh!!!!
That's the best way!! You're sure to get everything you want. Sounds like a fun project. I can't wait to see what you have in mind. I'm more than happy to give any advice I can. I've been involved in building a couple scratch built cars. It's a lot of fun!

Randy
