Nomad Boil Test

I don’t really get into M.R.E.’s (meals ready to eat/dehydrated food) as most users of alcohol stoves do. I just know that my Nomad cooks regular food faster than any other stove I’ve made…and that it can cook anything I want. I’ve done stews that took 4 hours to simmer, after bringing the 2.5 quart pot to a boil. I’ve done a crayfish boil in a much larger pot. I’ve cooked up collared greens southern style. I’ve done steaks and pork chops and a ton chicken. All of these things were possible because of the Nomad’s ability to adjust the heat output and because of its long burn time between refills.

As I don’t eat M.R.E.’s I’ve never done a boil test until today. Some people wanted to know the boil time using 1 ounce of fuel on high and on simmer. This is not possible. The Nomad holds 7 ounces. If I filled it with just 1oz I could do the simmer test but the high flame wouldn’t be high. As stated before the Nomad will burn with a high flame for 2 hours, and continue burning for another hour, but with a diminishing flame. In order for the test to be fair I had to fill it up all the way.

Room temperature water, 2 cups.

High test achieved rolling boil.

I next did the simmer test, again with 2 cups of room temperature water. It achieved boil, but not a rolling boil.

100_0901

Just out of curiosity I ran the high test again, to see if it would take longer with less fuel.

100_0902

3 seconds longer?!? UNACCEPTABLE!!! Into the scrap pile with you Nomad!

From what I’ve seen online the boil times for alcohol stoves tend to be between 5 to 9 minutes, though I’m a little unclear whether or not some tests were 1 cup or 2. Chime in and let me know what you guys think of these times!

The HermitFire

This is my newest invention in the ForeverFire series: the HermitFire, a denatured alcohol heater/stove. This is not the standard quart can toilet paper alcohol heater that’s on so many forums all over the net. This has an adjustable flame, 2 pot stands for cooking, and a heat hood to direct heat toward you rather than straight up.

100_0748

That’s a gallon paint can. Inside is a quart can filled with carbon felt.

100_0755

I didn’t have any Monster energy cans around, so I used a Venom can instead. It sits higher, but for this I think it works better. It’s mounted underneath the lid, and the paint lid is reinforced with 22 gauge steel. What you see on top are 6 T nuts, the inner three hold 2″ #10 machine screws for use with small pots. The outer three hold 3″x 1/4″ machine screws for use with large frying pans or pots.

100_0777

If used like this with a hiking pot the outer pot stand makes it virtually impossible for the pot to tip.

100_0780

Pretty cool! I didn’t plan it this way, just the luck of winging it! But where to store the pot stand legs when using it as a heater?

100_0754

I toyed with the idea of making a container like this out of aluminum, but this was so much easier, it’s a steel gum container.

100_0769

100_0770

So you’ve seen the stove application of this, now for the heater!

100_0793

This is the heat hood, fabricated from 22 gauge steel. Instead of the heat going straight up this focuses it forward.

100_0794

Side view with gratuitous shot of the worm gear.

You could heat with it this way, but it’s more efficient with a flame diffuser.

100_0809

100_0804

This is the flame at full power, about 12″ of blue soot free flame!

100_0805

A closer pic. I apologize for the lack of detail but the only way to see the flame was for the lights to be off.

100_0808

This is the flame diffuser with the HermitFire on low. All this does is help spread the heat out so that when it hits the heat hood it’s not burning on one spot, and actually seems to produce a more even, hotter heat.

Now let’s take a more in depth look at the HermitFire. A great deal of thought and work went into this project. The fuel cell (quart can with carbon felt wick) needs to be elevated in the gallon can. When testing I used an empty 7oz sterno can. I considered filling the sterno with fuel, just to have extra in case I took this contraption out in the sticks. But I wanted the base for the fuel cell to be secure, and it seemed over the top for the extra fuel. Then I considered using a beef stew can cut down to the height of the sterno can (approximately 2 5/8″). I could rivet it to the bottom of the gallon can. Perhaps I could fill it with sand for extra tip protection. Nix that! It’s heavy enough, and I’m always cautious around anything hot as is. Plus if the stew can was riveted where would the flame diffuser go? There just isn’t enough room between the quart and gallon can walls to store it.

100_0761

So I cut a beef stew can down and left 6 flaps. Note that it was actually drawn to have 8 equally spaced flaps, but those 2 were cut off so that the fuel cell stand can easily be pulled out. These flaps keep the stand can from sliding around, and because it fits with the pint can perfectly, all you do is set the fuel cell on it and it’s always centered in the gallon can. This way the fuel cell is elevated properly, it’s stable, and the stand is removable so the diffuser has a storage space.

100_0799

100_0768

Certain cans just happen to be perfect for the ForeverFire series. This diffuser is made from a chicken dumpling can. What a twist! =P

Because the choke ring is so large I made it out of roof flashing. This was also the first time I made the worm gear out of wood.

100_0752

I like how this adjusts, the screw always stays were you set it, with the aluminum worm gear that is not always the case. The problem with such a large choke ring is that when fully opened the bit of wood falls, and you can’t readjust the ring. So I added two choke ring supports, the one supporting the bit of wood is pictured above.

100_0763

Why this second support? These also keep the choke ring spread out evenly when adjusting, so that when fully opened all the air holes are exposed, rather than the choke ring resting on some.

Here’s how the heat hood is attached, two 3/4″x1/4″ machine screw.

100_0753

100_0789

100_0788

Simply slide the hood over the machine screws and push down.

This was a lot of fun! It’s hard to give a burn time on this, as cooking for myself requires a low flame…and by low I mean a blue 4″ flame. I have heated with it on low for 2 days, occasionally turning it up for more heat, but always readjusting it to low as this keeps the temperature consistent for quite some time. That’s 2 days and there’s still quite a bit of fuel left in it. I do believe that this works better/more efficiently than my commercially available denatured alcohol heater, as that burns on high for about 5 hours, and on low for 2 days, consuming about a pint and a half of fuel. Take THAT HeatMate! The cost of making the HermitFire was about $15 less than buying the HeatMate, not that cheap, but I made it, and I’ll save money on fuel.  There are some experiments I plan to do to potentially improve the fuel cell, but for now the HermitFire is more than satisfactory!

If anyone is interested in buying one of these please comment and I’ll get back to you with pertinent details.

Happy can crafting!

ForeverFire Nomad Version 2.0

Well I’ve used the Nomad for months now, and I still love it. As the carbon felt gets used more it does take a little longer for the flame to get to it’s maximum. Not a big deal, because the flame is also less finicky when started, meaning I don’t have to worry about an orange flame before it’s hot enough to adjust. I just light it and put my pot or cast iron frying pan on which helps to get the heat to it’s maximum. After a couple of minutes I adjust it.

The problem I had with the Nomad after heavy use is that the JB Weld that helps to bond and seal the Monster top to the quart can lid burns through, as well as where it was used to weld the nuts holding the machine screws.

100_0811

 

It’s not clear from the photo, but this makes the machine screw pot stand unstable, and it was only a matter of time until it collapsed while cooking. Here’s an under shot:

100_0814

 

At first I could just finger tighten the nuts shown, but that was rapidly failing as more of the JB Weld burned off the top nuts, and because the quart can lid isn’t that strong. Also, sometimes the tripod pot stand seemed a little bit precarious when flipping burgers or chicken in the frying pan.

My solution was to fabricate a new lid:

100_0812

 

4 legs are the least of the improvements. The biggest is that instead of setting the monster top on top of the paint can lid, I inserted it from underneath the lid. This eliminates the need for JB Weld. The second biggest improvement is that the pot stand isn’t resting directly on the paint lid. I used the lid of a steel soup can to reinforce it.

Because I found it unnecessary to adjust the pot stand height I tried using T nuts. This means no drilling through the lid, and no nuts underneath the the lid. Simply screw the screws down and the tension created when they hit the lid makes for an impressively sturdy pot stand.

100_0813

 

See? No nuts! You can also see the outer lip of the Monster energy drink top inserted from below.

I was always curious about mounting the Monster top from below, and I knew it would work on the Nomad because of another project I just finished. I also got the inspiration for reinforcing the lid with steel from that project. Blog soon to follow.

I got slightly off topic there! This new pot stand setup is sooooo much easier to use, sturdier, and all around better!

I’m a diy kind of guy, and have shown how to make this nifty adjustable alcohol stove. I know there are people out there who don’t have the time or know how to make these. That’s fine. Since I love to make these, is there anyone willing to purchase them?

100_0817

Please comment if so and I’ll set a price and make arrangements.

New Alcohol Heater/Stove in the Works

The past few days I’ve been tinkering with a bigger badder denatured alcohol heater that is also a stove. This thing should burn efficiently for a very long time to function as a respectable heater. By removing the heat hood it will be possible to cook normal meals on low, and large meals for several people on medium to high.

So far it boasts about a 12″ blue flame on high. It’s based on the ForeverFire. I have no idea what the burn time is with such a large flame, but it holds about a pint of alcohol! I’m hoping that it will be far more efficient than my commercial heater/stove, which does not have a heat hood built in. I had to make one for it out of firring strips and aluminum foil. The heat hood for this new invention will be made from 22 gauge steel.

I’ve got a lot more building and experimenting to do, but it should be done soon. I’m trying to pack as many bells and whistles into this as possible. It’s not exactly small when it comes to alcohol stoves, but it is portable, though that isn’t what it’s being created for. For the trip out into the woods I would use the ForeverFire Nomad, but for extended camping or bugging out/in this new guy would be my go to.

Update: Finished project here: The HermitFire

Denatured Alcohol Candle…but that’s just a part of it

The real title should be “Denatured Alcohol Candle/Stove as well as Rustic diy Recyclable Can Cook Pot with Lid”. In text speech that would be dacsawardrccpwl. It’s gonna be big, so watch for it in your messages.

So I was bored today and decided to see if I could make a denatured alcohol candle. I took a 2.6oz sterno can and drilled a 3/16th inch hole through the lid. Then I placed about a 4″x1/4″ bit of carbon felt through the hole, as the wick. When I lit it fuel started coming up onto the lid and burning with an impressive flame! Not a candle by any means, this was the easiest alcohol stove I’d made! But I wanted a candle! So I drilled an extra 1/8″ hole, and it worked just fine.

100_0729

Now if you cover the hole with a penny (thanks for the inspiration penny stove!) you get this:

Here’s a shot of the wick:

Pretty cool. But I was still bored, my can crafting urge wasn’t fed. I have several hiker pots. The past few days I was feeling campy so I was just cooking in old cans. But they were a pain in the hand and pliers to handle. So I made this:

100_0719

Rustic Cook pot with lid.

100_0712

Cook pot with hand saving handle.

100_0713

This is a 24oz pot.

100_0714

Manly rustic pot lid with bit of wood knob. Grrrrrrr!

Here’s the can the pot was made from:

100_0698

Here’s the can the lid was made from:

100_0699

It has a wider diameter than the pot can.

What follows is a pictorial build:

100_0700

100_0701

The handle was cut using a cutting wheel on my dremel.

100_0702

I then rounded it to fit the can with a sanding wheel.

100_0703

I used the discarded lids from both cans to make two of these dog tag looking thingamahiglycomplicatedjigs.

100_0704

Bend them. These are what connects the handle to the pot.

100_0707

I used aluminum quarter inch rivets to attach the elbows to the handle.

100_0708

Then I attached the handle to the pot with steel eighth inch rivets.

The knob to the lid was attached using an aluminum quarter inch rivet.

Pretty simple stuff, but I had alot of fun doing it. I’ll do it again using small tree branches, but as is I like the hobo frontier look of this cook pot. If you’re going to buy a camper’s/hiker’s cook set, why not go greener and instead of throwing away or recycling cans at home reuse them? You can’t customize store bought pots! Plus, a lot of you who read this already make your own stoves…why not take it a step further?

Daddy’s Got a Brand New Bag!!!

I was one of those kids who always used their kick stand, never laying my bike on the ground. I was one of those kids who regularly washed and waxed their bike. I was one of those kids who dreamed of a world where human powered vehicles were the only vehicles. I even drew a recumbent pedal powered helicopter…long before I knew there really were recumbent anythings.

Even after I got my license and my first car, I rode my mountain bike. As much as I could. When I was 17 I’d even make a 28 mile round trip to my church and back. I did a lot of stupid things when I was a kid. Church I mean, not the trip! No offense to any of you religious people out there, it’s just not for me.

I still have my license, though I use it only for work. In 2008 I gave up my last car, with joy. The cost of insurance, maintenance, and gas were just too ridiculous when I could pedal to most destinations and have more fun doing it!

In February of 2009 I got my first recumbent bicycle, Bentley. I haven’t ridden a “normal” bike since. Most people thought it was cool, yet hard to ride. (It’s easier to ride because it has a lower center of gravity).

Bentley the Wonder Bike!

Despite this snowy photograph, Bentley did not ride well in the snow. Which meant that most winters I would walk or borrow a friends gas guzzling death machine. Don’t get me wrong, I’m not anti-car. I’m anti-unresponsible lazy not paying attention in a hurry no regard for human life car driver.

Now I finally have an HPV (human powered vehicle) that I can ride year round, with efficiency and comfort!

Daddy’s Got a Brand New Bag!!!

This beautiful machine is a recumbent tadpole trike. Having two wheels in the front allows for better steering and braking. This particular trike is a Terra Trike Rover X7.

Side View of My Baby

The Terra Trike Rover has the highest seat available for recumbent tadpole trikes. Mine is at 19 inches. Most such trikes are only a few inches off the ground, allowing for better cornering, but just begging to be unseen and run over. This trike is only an inch and a half lower than Bentley. I’ve had no problems being seen, and cars give me a wider berth than they did on Bentley. Granted I use flags, a head light,  and a tail light…but I used the same on Bentley, it’s the wider wheel base that gets me that extra foot.

This trike is from: www.utahtrikes.com The difference between this trike and the one offered by www.terratrikes.com (The original manufacturer) is that it has a 26″ rear wheel, 27 speeds (versus 8 speeds), parking brakes, and my choice of custom color.
