*Canteen Cup Stove Modification*
For Use With Tuna Can Burners

I have used the trioxane and hexamine tabs, like many of you, under the GI canteen cup and stand for heating water, drinks and meals while in the outdoors.

I have found that in the last few years they are becoming more and more difficult to find in my AO and when they are available, they are very expensive.

Several years ago I read an article about Tuna Can Burners. Ever since that time I have been carrying one with me everywhere. It is great for starting a camp/cooking fire, and for heating and best of all, it doesn't cost much to make.

Since I have found these new burners, they have replaced the trioxane and hexamine tabs that were kept in my LBV butt pack. The tuna can burner replaced the commercial and military heating tabs.However,it was not as friendly to use as it could not be used in conjunction with the canteen cup or cup stove.

I have tried several different things from haywire racks to can racks… but nothing worked to my liking… until I made this little modification to the canteen cup stove.

All that this modification entails is four 1/8” holes, ½ inch from the bottom of the stand. This allows two rods to go through the stand from one end to the other which creates a rack that will support the cup stand on top of the burner.

Two holes on both sides, equally spaced

Pegs made from 1/8" metal clothes hangers are used as racks

Here we see the modified cup stand on top of the tuna can burner

(Notice: The burner is not centered under the stand. This allows the stand to slip over the burner and to fit snuggly. The burner slides into the feeding port of the stand to stablize the stand. Both cup & stand sit solidly on the burner.)

Here we see it in use with the burner burning. One problem with this setup is that the tuna can burner does not burn clean like the trioxane or hexamine tabs do. The stand and the bottom of the canteen cup get black with soot. However, this is easily cleaned.

Now some "Performance Tests"

- The GI canteen cup holds appoximately 2½ cups of water (or other fine liquid).

- Ambiant temperature: 60ºF
Time to boil 1 cup of water: 5 minutes (hard boil: 8.5 minutes)
Time to boil 2½ cups of water: 8 minutes (hard boil: 20 minutes)

The nice thing about it all is that it doesn't take extra room than it used to. The two pegs fit inside the cover with the canteen, cup and stand.
