BB - you sure you're not an engineer?

I heard that!

Got my BB stove in the mail. Hoping to try it out this weekend if I get to go canoeing Saturday. We always stop to have lunch somewhere nice. Supposed to be 65 degrees and sunny 49.gif

Mine works better then the stove that came with my Caldera cone.

You sent me an obsolete stove? I demand a discount! :lol:

I love obsolete...it means it's collectible.

BB - have you got any diy directions for a windscreen that a simpleton can put together?

What's in the eye drop bottle and 2 baggies?

This DIY windscreen looks about my speed.

I've been looking at my stove for the last two hours and I can't find the advisory notice you speak of.

I don't understand the comment about the thread...why are you putting a different top on your bottle?

I'm confussed.
I believe you are saying you can't make the capilary hoop out of the bud can? Pic just compares the two cans- not the design?
I used the Coor's light can's because the thinner wall and quick heat transfer, likely the problem with the bud can you describe if I understand correctly. I found many bud can designs required a primer cup.

Assuming the outer can is the only difference in design it is likely that it is acting as a heat sink and preventing or reducing vaporization. The fact that it works in the cone with the heat reflected back to warm the outer can seems to support that theory.

What about making the creased liner taller by about an inch. Trim between at the creases similar to the bottom of the piece and remove every other or every third tab and bend it back into to the center to allow the liner to heat faster and start the capilary draw so it primes. You could also try just a slight notch at the top and do a "tab a into slot b" type connection to test it out. If you get the heat transfer along the inner wall going it should overcome the outter wall issue.

What's in the eye drop bottle and 2 baggies?

"Camp Soap" is in the eye dropper and the two little packages that look like baggies are esbit tabs in case I run out of HEET or need to a fire when everything is wet. The windscreen is made from aluminum roofing flashing and the ground shield is from the bottom of an aluminum pie pan.

Maybe my eyeball tape is broken but...
Looks like the burner holes are lower due to the fiddling you had to do to get the bud collet to work.
Which made the holes lower down the wall and unable to get up and over the lip to light? Had that issue before with the coors cone top.

Coke can collet is flat, this one curved a bit so more volume and less pressure coming out for the fuel to light (pure speculation)

For the inner wall- what about a slightly bigger thin wall can and over lapping one corrigation and sealing with JB weld to get just the right DIA inner.

Style points are important so I understand the desire to get the pretty cans to work but sometimes it don't.

My initial thought was-

I think you've mentioned that before and I forgot. The short Dasani bottle is a little less than 300 ml which would be perfect for 4-5 days.

BB, I always would recommend substance over style, and function over fashion.

Bird Brain - I think Just Bill has the right idea with the jet holes being too far down from the rim. If you have looked under the top of a gas stove, you may have noticed the tubes running from the burner to the pilot light. Maybe build a short duct on the outside of the bottle running up from one of the jet holes to the rim? The end of the duct would have to be close to the hole to capture some vapor, but not prevent adjacent holes from igniting. I have never done this, so not sure what it would take.

Or just put a ring or cone around the jets to redirect them upward. Not sure if aluminum would survive the heat of the jets. If it incinerates, Titanium Goat might have some 0.005" titanium foil as a possible fix.

A difficult bloom may also be caused by holes that are too far apart.

An all-metal capillary wick does not need folds or bends to work. Please see http://donsmaps.com/stoves.html for other ideas. My metal wicks are old school, but I use eyelets not staples to secure them.

I have been collecting can measurements for a while. Here is my latest list. Hopefully this will be useful to fellow stove builders. I welcome additions and corrections. Prices, sources, and availability are subject to change. I generally shop in the greater Milwaukee area.

The following is a list of aluminum and steel containers and other items sorted and grouped by outside diameter or width. All diameters are outside, except mouth diameters, which are inside diameters. Measurements are approximate. The outside diameter of the side wall is omitted for some of the larger cans, but can be estimated by subtracting 1/16" from the outside diameter of the rim.

Wow, StovieWander, you and BirdBrain continue to amaze me.

BB-
You are playing with two designs that I never did- the capillary hoop and the bud bottles. But that said I think you will either figure it out and make your pretty can's work, or settle on the already perfect stove design and seek out some pretty can's to match it.

In that vein may I suggest one such pretty can you could likely work with-

I built some pressurized side burning stoves with soda cans, and three with Bud Light bottles, but never came up with anything I really liked. You seem much closer to optimizing your design than I ever was. I pretty much gave up on pressurized side burning stoves, at least the kind with pin holes. Most of my stoves have had 1/8" holes and not much pressure. One exception is a stove with sixteen 1 mm holes in a 1 1/4" circle at the top, which worked quite well at -10F, and is the best stove I have made to date. It doubles as an alcohol candle, as seen in my avatar, but an additional piece is needed to make it work as a stove. I have been meaning to do more testing and optimization before publishing plans and test results.

Damn it you guys are making me want to tinker. I really like to go out to the man cave, turn on the tunes, get a drink and start making something .I may just shutter the sewing machine and wrenches for for a while. Hmmm I have been eyeing those Coors Light and Bud Light can bottles ....................

I tested my latest stove this afternoon. It draws inspiration from the supercat, but adds a steel combustion ring and a metal wick. The burner is 2 1/2" in diameter, 2 3/4" tall, weighs 20 grams, and supports a pot. I successfully boiled water twice today.

The first test used 30 ml of denatured alcohol. Two cups of 60F water boiled in 11 minutes. The total burn time was 16 minutes.

The second test used 20 ml of denatured alcohol. Two cups of 57F water boiled in 12 minutes. The total burn time was 13 minutes.

The air temperature was 29F. Wind was moderate. The sky was partly cloudy. A 23 oz. Armour Beef Stew can blocked wind and kept hot exhaust gases close to the pot, with three screws as legs, a large central hole in the bottom, and additional perforations in the bottom. A Halulite Minimalist pot with original lid held the water and a 13 gram stainless steel tablespoon.

The fuel efficiency is good enough to warrant further development, but the time to boil is disappointing.

I have three ideas for boiling water faster. First, start with fuel near body temperature. Second, increase wick size. Third, use a larger diameter combustion ring. Stay tuned for updates.
