The fuel pictured?

Did I miss the dimensions of the stove?

No, I have not given them only showed it's the same size as the bushbuddy. It's about the size of a quart paint can. Weighs 3.8 ounces.

I used cherry and black walnut wood chunks the same size as in the video. The stove flames went out and the heating continued from the large amount of hot coals remaining.

The fuel used in the video was cherry.

Does lighting from the top reduce the flame-thrower effect mentioned further up the thread?

I cannot view the video on my iPod Touch.

Yes, It tones it down quite a bit.

I did some preliominary tests today in preparation for comparing single wall to double wall top lit stoves. The Bushbuddy and a DIY single wall.

Fuel will be 2oz of clothespins. Fuel will be stacked as in the photos. Just full size clothespins will be used.

I'll try using vaselened cottonballs and low odor mineral spirits as tinder lighter. I used paper today on 2 tests but the BB had a hard time lighting with it.

Photos show the BB having charcoal left after the flames went out. It is low on oxygen to give a complete fast burn. Eventually it turns to ash.

no timing was done today. Both stoves boiled water with the 2oz of fuel.

Tomorrow more tests :D :D

I did 2 tests today to determine what to use to ignite the 2oz batches of wood.

1st test the DIY stove did not ignite. I used vaseline on the cotton "cosmetic squares"

2nd test the BB did not light. I used 5ml of pure lamp oil on the cosmetic squares.

I was able to put a pot on the DIY stove and got a boil 7 min. after lighting the stove. Took about 5 min to boil once the pot was place on. Beginning water temp was about 85 degrees guessing. it had been acclimatizing to the outside temps for about an hour.

Same amount of fuel and lighting tinder used for both stoves. Clothes pin fuel stacked in the same manner.

My intentions are to show that a single wall stove is as efficient/good as a double wall. Both stoves are the same outside dimensions.

I did 2 tests today. The 1st I used 1/2oz denatured alcohol as starter....whoaaa!!!!!!! that was a radical way to get them started. :lol: There was enough vapor in the area around the stoves to making lighting easy......got to within an inch of the BB and....wwhhooompfffff....both stoves lit at same time :lol: I have it on video but did not upload it, maybe some other day :( Both stoves burned from bottom up and side to side and also on top :mrgreen: )

For the second test I used 3 pieces of the cosmetic squares soaked with 5ml of lamp oil.(yesterdays test I used 2 squares)

Both stoves top ignited nicely today and both boiled 2 cups of water. I think we got the basis for some good tests to follow.

Let's think positive............top lighting is doable with paper and liquid tinder fire starter.

These methods are a good way to work your way into batch loading. Most of you that have wood burners are confirmed twig feeders and will probably remain so. For all the new comers that are "thinking" of burning some wood down the road seriously think of doing "batch" top light technique. Some of you are vertical twig stackers that light from the top(would like to see videos)

I'll be doing more testing to determine "repeatability" using the 2oz. fuel and 3 piece, lamp oil soaked cosmetic squares.
