For those that were interested in my
Hubcap Fire Bowl that I posted back in April, I wanted to give an update after a Summer of use.
It has worked great. I got a little kidding a few times when I got it out but everyone enjoyed it after I fired it up and even requested on nights that I didn't get it out soon enough.
I have added a small poker that I made out of an old wrought iron plant hanger, it is small enough to store inside the hubcap. Since I such small fires you don't need a log poker, but is nice to have to stir up the fire and poke it once in awhile. I also added 4 small holes just outside the chrome part of the hubcap to add a little more air for better wood fires.
On the fuel front, I gave up on alcohol, even though it made a nice clean fire. I made a small burner which helped the burn time but it still was to short a burn for the cost.
The cheapest fuel was the scraps from under my radial arm saw. Since it is a small fire I discovered early you need really small firewood. I finally settled on no bigger than 1.5"X1.5"X4", larger pieces tend to smolder to much in such small fire. A 5 gallon pail of scrapts will give you 8-12 hours of fire. I used a small piece of wax log as a starter under the wood fires. The wood is nice because you don't use the lava rocks and can add a couple of small chunks at a time to extend your burn time without a large commitment of how much longer you want to sit by the fire. Using scrap lumber gets you out of any problems transporting firewood from outside the area which is prohibited many places.
The wax log chunks with lava rocks dumped over them still makes the fastest and most controlled fire. I started off the season using chunks of fire starter logs. A block about 4"X4"X3" would give about 45-60 minute fire, to extend the time I would mix more wax chucks in or throws some wood on top. I wanted a longer burn so I have tried 2 different wax log products and they burn longer than the fire starters. I tried Java-Logs made from coffee grounds and Pine Mountain brand. Both I sawed off slices on the radial arm saw. My test chunks were only around 2-3" (about 1/2 lb) long by the diameter of the log and they gave me a 90 minute burn. I plan to increase the size of the chunks next season to see if I can get the burn up to 2+ hours. At $3-5/5lb log which could be cut up into 5 or more chunks it should make an economic alternative and easy to carry extra along. The wax logs are less smokey than wood. An added feature of the wax logs is when they are done burning they go out very fast, from when you notice the fire getting weak and you stir them up a little, to out in about 5 minutes (still very hot but no open flame).
I have also attempted to make my own fuel molded to the shape of the hubcap. I have tried both soy wax and regular wax with a variety of stuff mixed in: coffee grounds, sawdust, pine shavings, and cedar shavings. My favorite combination was coffee and cedar in soy wax. It gave a good burn length and a nice smell, but unless you can get the wax cheap it is cheaper to buy the wax logs. The best prices I could find on wax was $2-3/lb and to make a reasonable burn length would take a 1/2 lb of wax, so even with everything else free why bother.
So that's my first full season of use report. The fire cap, poker, a long lighter and some fuel all fits in a denim bag my wife made. The lava rocks go in the coffee can base. The bag, a 5 gal bucket of wood, lava rock can/base and another coffee can full of wax log chunks fit nicely in my truck wheel well with the slide in camper in, with room to spare, and gives us a weeks worth of evening fires.
