The Caldera Clone

> the only issue I have is the pot when filled with water has the possibility to slip off the top of the clone.

The caldera cone and clone are intended to support a pan by fitting under the rolled lip of the pan. If you engage the top of the clone with this lip, than pan cannot slide out.

If your pan doesn't have rolled lip that the clone can slip under and stay there securely, it's not really suitable for use with a cone/clone...

I have the Blacks Solo pans, and they're nice, but the lip isn't quite enough to hold it securely in a clone, even though I've made one for it.

If the pan opening is shallow enough, you can make another slot/tab joint below the handle opening in the upper Flissure half.  This is what I've done with the Blacks pan, and it's just about enough to keep the thing stable enough to cook with.

Quick  test burngot 16oz of water to a rolling boil in 9 minutes on about 13ml of denatured alcohol.  Not to bad.  Will run some tests against the super cat to see which one is most fuel efficient

ah - I see your pan doesn't have a rolled rim - no wonder it slipped down.

 But, good that you have solved the problem with another tab.

I guess you did heat up the flashing to soften it where the tabs are folded?  They snap off easily else.

 let us know how your stove tests go

I used a Red Bull chimney stove for a couple years.  They work well. I tend to use a Starlyte stove mostly nowadays.  Never got on with any of the various supercats I've made.

Hello Captain

I discovered your 2-parts Caldera Clone which could become the perfect pot support/windshield I've been looking for years. But here is my problem : I used the script given on zenstove.net and printed it out but it doesn't match with my pot, especially where the handles are connected to the pot (basically there is no space to let them unfolded). As you probably understood, English is not my mother tongue so this problem must be caused by a misunderstanding of variables (I guess a scheme on zenstove.net could help)

So I read a part of the thread and I saw that you performed some tests with a Trangia Burner and a MSR Titan Kettle. Fortunately, I have the same cooking set. So I wondered if you could send me the script you used for building it, it would help me A LOT and, in the meantime, save me the study of the best burner offset, as the holes number.

my printer configuration : A3 and - just in case - A4, ISO
my email : olivierdemattia at yahoo.fr

thank you in advance

I always thought the perameters were pre-set for a Titan. ?

Indeed, the pot heigh and diameter match perfectly. That's the "handle settings" I don't understand...

I had issues with my handles on the coleman. There are some large rivets and it made it difficult to get a good handle measurement. What I did is left that part uncut when I cut out the template. Then I went back and made small cuts, dry fitting the pot to see how it fit. Took a little longer but I have a good tight fit and then handles don't get in the way. 

Right, i'll have a stab at explaining in CP's late night abscence.

HandleWidthTop - Measure the width across the top of the handles, input the answer in millimetres.

Handlewidthmid and HandleWidthBottom will be the same as the top unless they taper towards the bottom, which if they do you'll have to input those measurements too.

HandleDepth is simply they measurement from the bottom to the top of the handles at their longest point.

I'm a little bladdered at the moment, so apologies if that's no help whatsoever.

Olivier, the script that Zen Stoves generates is for a 'generic pot', which is based on an MSR Titan, but has handle cutouts that are not as deep as are needed.  This was to try to make it clear how the script worked.

To get it to suit your MSR Titan, you need to adjust the values.  Here are the values I've used for the Titan kettle:

/panHeight        86    def % height of pan
/panCircumf        364.4    def % circumference of pan outer walls immediately under rim
/handleWidthTop    30    def % width at top of pan handles
/handleWidthMid    8    def % width at shoulder of pan handles
/handleDepthMid    18    def % measured from top of pan to below top of handle
/handleWidthBot    6    def % width at bottom of pan handles
/handleDepth    72    def % measured from top of pan to lowest point on handle

The middle and bottom widths can usually be smaller than the top, because the handles are held together when you hold the pot in your hand.  The sloping sides of the cone mean that the opening for the bottom of the handles is along the tapered handles, so the opening does not need to be as big.

Or, you could do as Red Fish suggests, and experiment with a paper template, starting with a small handle opening, and cutting small adjustments until the handle fits.

If you haven't downloaded the instructions file from ZenStoves, I would strongly advise it.

Hello,

Sorry, I was outside this week-end. Thanks for all the answers. It helped me a lot and despite I had to print the mock up on A4 sheets (It didn't worked out on A3 due to scale issue I guess), it fits nicelly to the pot. I will check if the two parts can be rolled in the pot but I think I'll have to reduce the burner offset. (46mm height for the burner and 30mm for the offset)

I had to print the mock up on A4 sheets (It didn't worked out on A3 due to scale issue I guess)

If you select the /largePaper option (set it to 1), it should select A3 paper size in the PostScript.  Check the script generated by ZenStoves; he may have a bug.  If there's a problem, just use a simple text editor to change the values; that's how the script used to be adjusted to a pan and burner...

There should be no scaling problems.

A 46mm high burner and 30mm flame gap will make a clone that may well be too tall to fit in the Titan kettle.  The paper prototype will show you...

Im attempting to make a cone for a Snowpeak 700.

I've been looking at Captain Paranoia's excellent Cone Pot Stand Tool.

http://zenstoves.net/PotStands-Conical.htm#ConeTemplates

However Im immeadiately lost.

For instance

1.] Measure from bottom of pot to where you would like cone to stop

How Do I know where I would like the cone to stop?

Does anyone have the correct dimensions saved on a word document for instance, which are suitable to enter into the Cone Pot Stand Tool calculator?

To produce a template for a Snowpeak 700 Mug?

Well you'd want the cone to stop where the lip starts on the mug, so it has something to rest on.

Mmmmm.......

Lol, this is the measurement, as far as i can ascertain from your post.

LOL. You know I actually read it as meaning measure from the bottom of the pot down, to where Id like the cone to stop......

 I.E I was trying to figure out how much space to leave under the pot for my stove...
