golden locost...?
Who saw "salvage squad" on the box last night - model T racer with polished brass bodywork. It's a look that could work on a
locost... is it allowed? how much heavier than ally? Anybody made one?
cheers

i can't see why it wouldn't be allowed, but i get the feeling it might be quite heavy

Like Staple Balls says no reason why it wouldnt be allowed...but
The density of brass is about 8400kg/m^3  (heavier than steel!) compared to ali which is 2700kg/m^3 
So your brass bodywork will weigh a nice 3 times as much as your ali bodywork!! I worked out youd have about 15 kg of ali in a normal chassis....or
45kg!! of brass...
Would look cool....

having never played with brass i'm not sure. but would it be an option to use thinner sheet, like 0.8mm instead of 1.2mm? that'd drop
quite a bit of weight

With 0.8mm it would still weigh twice as much as ali  youd have to go down to 1/3 thickness...ie 0.4mm to keep the same weight as ali. And that may
be a tad flimsy  (But brass is about 1.5 times stiffer than ali....)

Robin Hood are supplying their cars using Stainless coated with Titanium or some such exotic material. The resultant panels are gold and shiney.
I guess it ends up being a little heavier that Alu, but looks good in the pcitures.

yeah, i realise that, but it'd be better than 45kilos, then would it be sturdy enough thinner like that?

ouch that is heavy... I'll have to tot it up for sides bonnet & boot, with black wings & nose...hmmm
Is there an issue with fatigue resistance/ cracking? Ugh - keeping it clean, doubt many lacquers are up to automotive spec..
I guess I'l just paint ally after all - sigh...
cheers

one of my first thoughts was if anodised alu was an option, but i'm not sure you'd get the right look

Brass is 1.5 times stiffer than ali. But without sitting and doing a load of maths i dunno if it the strength of the brass would be comparable to the
ali.
Also brass is a bit more brittle than ali (correct me if i am wrong :p) So it will crack easier when you bend it (work hardens faster iirc) which also
means it would be more prone to fatigue.....

I saw it at a show last year - somehow it just looked cheap and nasty (or was that the car underneath  ). It wasn't gold or brassy in colour
- not very attractive IMHO.

...and don't forget that brass is VERY expensive in large sheets, especially when it's polished with protective sheets stuck on, as they
used.
rgds,

P.S. I wouldn't have driven that car at anything above walking speed around Brooklands! Or with that wonky wheel, either!

Anodised Ali
When I built mine the ali sheet supplier was Alcan (Edenbridge) they could supply anodised sheet in all sorts of colours ,(gold .red ,blue) but I
thought it might look grim if it got scratched.................
