Second SVEA

The nice lady at A&H told me that it might be possible to bend the burner of the damaged SVEA back in line. The danger, she says, is that it might leak at the entrance to the tank, and if it does, it can’t be fixed.

So I held the tank firmly down on my desk, looped three fingers around the burner, and pulled. Two or three good pulls and the burner was more or less in line. It still looks slightly tilted, but I don’t want to tempt fate by bending it back and forth for perfection.

It boiled a quart of water, then simmered for about ten minutes with no sign of leakage. I held a lighter flame next to the joint between the tank and burner but detected no sign of leakage. So now it looks like I have two SVEAs, a 123R and an original 123, all for $23.50 plus shipping from eBay.

The older stove seems to need a rebuild though. I can see no sign of a wick in it, and I’ve learned that you should never let a SVEA burn dry, as that can scorch the wick. This leads to inefficient burning – I thought it burned out too fast the first time I tried it. I have a wick on order along with the rebuild kit and replacement key from A&H.

Antigravity Gear pot

The AGG two-quart pot arrived and it’s a winner.

It’s hard-anodized in that attractive Calphalon grey, ultralight, and similar in construction to the Walmart grease pot, with some important improvements:

  • The rim rolls out, not in – better for cleaning and for grippers
  • The lid is flat and rests atop the pot, not domed and fitted around the sides
  • Instead of a big plastic handle, the lid has a clever loop bent so it stands up slightly so it can be hooked with a stick or lifter.
  • The lid is not anodized.

    At $18 it can’t be beat. Anodizing is supposed to improve bend strength, a real advantage when aluminum is thin. It won’t be quite as easy to clean as non-stick, but for this pot that’s a non-issue, as boiled meals will be easy to clean out anyway. If you want to fry or roast things, that might leave some tough residue, but I think you’d need a heavier pot anyway.

    I’m using WordPress, an open source php-based blogging tool. I have imported all the entries from my TypePad weblog. The Movable Type import worked fine, and now I can close and cancel the TypePad account.

    Planning for GPI

    Having decided that the Grease Pot Improved (GPI) concept is worth checking out, I’m going to do some tests and publish the results.

    Things I want to check are:

    1. Boil times with uninsulated/insulated pot lid
    There probably won’t be a huge difference, and boil times are variable anyway.

    2. Temperature after time with uninsulated/insulated pot lid
    I will probably boil water, then let the pot cool for five minutes and check the temperature. This to determine whether the insulated lid alone is useful for keeping food warm.

    3. Temperature after time with GPI cozy/over top cozy
    My concern is that the GPI cozy leaves a gap at the top, which will hurt performance — but will it be enough to care about? an over-the-top cozy is slightly less convenient than the GPI and won’t give any boil time improvement but should be thermally optimal.

    The key to conducting this test will be to order things so that all the tests with the uninsulated lid are done first. Then I can glue on the insulation and proceed to the other tests.

    When? Maybe this weekend.

    I ordered the AGG pot

    I exchanged email with the Tin Man in which he explained that the hard-anodized pots do not have any additional non-stick coating. This is exactly what I want, non-stick over HA is just taking an incredibly tough finish and making it less durable.

    Since I already have a bunch of Reflectix I’ll make my own cozy for it. The AGG prices are really reasonable, especially for the pots, which are uniquely low-priced and light.

    AntiGravityGear 2 Qt. Aluminum Non-stick Cook Pot – AntiGravityGear.com

    Here is it. 2 quarts, hard anodized, 5.9 oz. $17. Sign me up.

    Compare to the Snowpeak titanium 2 quart pot at 9.2 ounces and $80. The Snowpeak includes a frying pan that probably accounts for most of the extra weight and could be left behind. It also is probably closer to (maybe even over) its nominal capacity. And it has builtin handles – add 1.4 oz to the AGG for the pot lifter. But the AGG pot seem perfectly practicable for two people, with a net weight probably one ounce over the Snowpeak alternative, and I could buy more than four for the price of one Snowpeak.

    No decision just yet, I need to think about what we eat from as well. With two people you can’t just use the pot.

    The AGG lid, unlike the Snowpeak, won’t really work as a plate. The bail gets in the way.

    Grease pot improved

    I field-tested my solo cooking system in the back yard yesterday.

    I made a non-field-worthy pot cozy out of Reflectix and masking tape, as a test. Rather than have the bottom free and put a cup-like cozy over the pot, I decided to make a cozy like a sack that the pot goes into. A panel of insulation is attached permanently to the pot lid and stays in place while cooking, possibly helping to improve efficiency even when the full cozy isn’t used. After boiling, mixing etc. I just put the open pot down into the cozy (since the grease pot has no handles it needs to be open so I can use my pot gripper) and then put the lid on the pot.

    I decided to use a package of Trader Joe’s white cheddar mac & cheese as a test. It required eight minutes of cooking, a fairly tough test.

    I used my grape-juice can stove and one ounce of alcohol. Conditions were calm but with occasional gusts, about 48 degrees F.

    Three cups of water didn’t quite boil when the stove went out at ten minutes, so I put the pot in the cozy, and let the stove cool for fifteen seconds or so. Then I added another half ounce of alcohol and relit it, putting the stove back on.

    In another minute or so I had a full boil. I added the macaroni, stirred and covered. The aluminum flashing potstand/windscreen weighs more than a foil windscreen, but it shows its value when you need to stir sticky macaroni over heat.

    After about a minute I had a full boil again, so I started my timer and cooked the macaroni uncovered at boil for about one more minute, when the stove started to go out. That’s when I quickly stirred one last time and put it in the cozy.

    At the eight minute mark the macaroni was nicely cooked. Drained, it easily melted the cheese mix and some garlic butter I added (cheating a bit, there.) Not a bad on 1.5 oz. fuel.

    The cozy add about 1 ounce to the weight of the grease pot and I think it’s a winner. If you do any cooking (vs. boiling for freeze-dry) it will more than save its weight in fuel. Next step is to put together a robust version, probably with aluminum tape, and fasten the top insulation to the lid with silicone.

    Purpose of this blog

    This blog is really here to help me learn about blogging software and techniques. The content consists of the things I’m doing to get back into backpacking after about a ten year hiatus. I’ll be using lightweight-ultralight principles to lighten my load, without going over to the ultralight camp. And certainly, no “fastpacking”.

    Tarptent and SVEA update

    I set the Cloudburst up in the garage and seam sealed it. The directions say to seal the stress point seams, and don’t mention the ridgeline, so I didn’t do that.

    I used GE Silicone II sealant diluted with mineral spirits. A wooden-handled cotton Q-tip gave me great control, and I wiped all the seams with a paper towel afterward to smooth things out.

    The Tarptent seems pretty roomy, not as bomb-proof as my 8+ pound Moss Stardome, but certainly adequately protective.

    The SVEA seller responded to my email, he’s been busy with family business but to apologize is sending “something extra”. I’m looking forward to trying out the stove.

    Currently looking into lighweight cooking gear for two. Most of the popular ultralight gear is sized for solo hikers, especially through-hikers with minimal cooking requirements. If I’m going to get Julie interested I’ll need to find something she can cook in, not just heat water for freeze dried stuff.
