I wandered into my local university bookstore art department and found this tiny pencil sharpener, the Kum 400-1K and it is made from MAGNESIUM :) It can double for fire starting material along with the pencil.

4.8g for the sharpener and a whopping 2g for the Integra scorecard pencil. Johnny Muir is quaking in his grave :)

Here are some prelim test pics and results from the “Prototype” These were done in my workshop at ambient of 65 degrees. I am using a evernew titanium 750ml pasta pot with 2 cups of water at 65 degrees for all tests.

First Test is with the burner filled with 4 oz, rested for an hour. Note this did take 14 Min to get to 212 deg, this is the first test and there was 4 oz of denatured to warm up.

So now the thought is to check with a windscreen although not much draft in workshop. This is an aluminum one with stakes as a pot support that will hold the pot, same evernew, 1 inch above the pot. oops changing 2 variables. Point here is to see if the windscreen creates greater temp over more surface. This test i get 11:49 min

So next I go to look at the height of the potstand and run a test with a 1 inch gap between burner and pot but no wind screen. This test i get 12:31 min

So the initial observation confirms what Zelph found, reduce the height of the poststand to get to approx 1 inch. I am not sure if the windscreen helped much on the bench, i am sure it is a necessity outside

I ran the prototype with the 1.5 inch SS for 7 consecutive burns, the 7th ran out of fuel at 203 degrees, close. Damn efficient! So I would bet that you could estimate 4-6 boils with 4 oz of denatured outside under summer conditions with a windscreen. I did a run using the standard starlight and boil times improved by approx. 1.45 min, bench results

So I concur with the suggestion to reduce potstand height and open the burner port size

Hey this was my first post, followed the instructions and it worked. Nice burner/stove

Cheers, Skuz
