Making a Cone using Captain Paranoias Cone Potstand Tool on Zenstoves.net - busting the myth?

You know it must have been about 7yrs ago that I got the script for the clone with fissure off CP, still cone less :(. Between looking for a gaff to no computer to not sourcing materials to general laziness i've always put it off.
So this time am motivated & want to get it done, so to that end can anybody tell me the thickness of ti I'd be looking for & a place to source it?
I was thinking about using alu foil, but i do cook from scratch with alcohol & was wondering how that would stand up to the job?
Cheers for any help that can be given

I'd highly recomend Ti foil even tho' it's ££'s more. Maybe experiment with Alu and graduate to Ti when you've "caught the bug" :D I've just added an update to the other thread re. suitable Ti foil.

I have just placed an order for the 0.0078" (0.2mm) aluminium flashing.
PM me if you would like a chunk, it's the 12" x 10 foot size.

@Gadget, Seen that on the other thread there. Got some ti foil there now but am very tempted, just wondering how much postage on to ireland would add onto it, could be close to as much again depending.

Curious.
Just did the sums comparing the 0.1mm Ti with the 0.2mm Al. The thicker aluminium works out lighter.
Is the thinner titanium tougher... or just more fashionable?
Ti has a higher youngs modulus, yeild stress, better fatigue resistance & retains its strength at higher temperatures.
In theory a Ti cone will withstand the repeated rolling & unrolling a lot better than Ali.
My head sums would put a 0.1mm Ti cone about 20% lighter than a 0.2mm Ali but we're only talking a few grams.

I would have thought the ti would be stronger, withstand longer?
Which has the better pack size? I reckon with a fissure you'd have more space in the pot with the ti, might be minimal though am only guessing.
(oh, just seen the above)

Al thickness = 0.0078" ≡ 0.19812mm
SG of Al = 2.72
Ti thickness = 0.12mm
SG of Ti = 4.50
so, for the Aluminium, 0.19812 × 2.72 = 0.5388864
and for the Cooltanium, 0.12 × 4.5 = 0.54
∴ for those thicknesses Aluminium is 0.2% lighter.
So a 40g cone in the Cooltanium, would be 39.9g in the Aluminium (and about ¼ the price).
If I had more disposable income I would be one of the Ti-coolkids too... jealousy is such an ugly emotion.
(Though, if you are a proper grammar nerd, that's envy, not jealousy)

i made a direct clone of the fkeg caldera cone from 0.005" grade 5 ti and weight was 1g lighter than the ali.

Weight ratio Ali to Ti = Thickness ratio * SG ratio (2.7/ 4.5)
For 0.2mm Ali & 0.1mm Ti = (0.2/ 0.1) * (2.7/ 4.5) = 120%
For 0.198mm Ali & 0.12mm Ti = 99%

Those wanting longevity & perhaps the ability to stick it on a wood fire should think about Ti & those concerned with cost Ali.

I've used Ti and Alu for cones……….own I make Ti cones for my use, and Alu cones for the kids to treat with the disregard that teens have ;):D.
