Checking out Four Dog’s Bushcooker LT Mini

Thanks for bringing this product to my attention….I wasn't aware of it. $32 seems pretty reasonable too, and the weight looks great. Sure, its probably not as efficient as a caldera cone, but you do get the ability to use a wide range of pots.

I was particularly happy with the fact it boiled 24oz of water with less fuel than they claim for 16oz.
'Course I've only tried it in my kitchen, but it made a very good impression.
Also going to try it with Hexamine tabs, and even less fuel. I don't really need my water to come to a boil, especially when it's just being used for coffee.

Hi Owen. Put your new stove (& screen & pot) to the test…grab either Ben’s or Glenn’s Stove Efficiency Spreadsheet and run a couple of tests and take the average. Post your results in the ASEPT thread.

Above, you said 2 cups of water on 22 ml of fuel. Getting 470 ml to boil on 22 ml of alcohol doesn’t sound all that efficient, but it’s impossible to know without a couple of missing parameters, such as initial water temp, your elevation, fuel used. Maybe the efficiency is great?

I would guess you should be able to make at least 60% efficiency with this or a similar setup, which would be decent. I think this because I have a similar short, straight (not cone) windscreen-with-ti-stakes setup, and I’m getting test results showing efficiencies around 65%, respectable for straight cylinder windscreens.

The other comment I’d make is, test your setup for wind resistance. I’m seeing some large-ish windscreen holes that look like they line up vertically with holes on the stove (can’t tell due to perspective), and a fairly wide gap between windscreen and pot; these are variables that can lead to wind vulnerability.

Hi again Owen. I took a blind flying leap at calculating efficiency, based on your report above. Assumed 70F water, that you were at 1000 feet elevation, that your actual boil temp was 210, and that you were using SLX or other off-the-shelf denatured as fuel. If these parameters were true, you'd be getting 53% efficiency on your stove, based on the Ben's Improved worksheet.

Yeah. Try 710mL of water, and 18.6mL of alcohol.

"Above, you said 2 cups of water on 22 ml of fuel."
Nowhere did I say anything about using either 2 cups of water, or 22mL of fuel.

Moving on…
Today I tried the stove setup with two Coghlan's "Fuel Tablets"/Hexamine(with the exhaust fan running).

Four Dog claims "14 grams esbitt/heximine will boil 16 oz in 7 minutes–conserving fuel and saving you time."
Again, I'm using 24oz of water, instead of 16, which began to boil at ~8min 6sec…

…and would have doubtless boiled an even larger amount, given that the two fuel tablets continued to burn for several minutes afterwards.

I like the simplicity of the Hexamine, but it does leave a residue on the pot. The fuel tabs not having nearly as much odor as the Esbitt tabs I've used in the past was a pleasant surprise, though.

More than satisfied with the performance with both denatured alcohol and Hexamine tabs.

Really? That's odd, that's what I read the first time through your post. I noticed you'd edited your initial post, and I did notice different numbers the second time I looked. I assumed you had revised. If those much better numbers are the correct numbers, run them through a spreadsheet and see what you get.

I notice you say you are boiling 710 ml of water in a SP Trek 700. You gotta teach me how to do that! I would have water all over the place if I tried that.

Sounds like you're satisfied, and that's all that counts.

There were no changes to any of the numbers in my original post.
The Trek 700 holds 28.25oz/835mL when full.

Interesting. Trek's website must be in error, then–they say 24 oz capacity.
