Penny Stove, Scollop+Double Scollop

Introduction: Penny Stove, Scollop+Double Scollop

Yet AnotherPenny Stove, the Scollop Method.

Near foolproof and easy to do, multi layer cans are go.

Step 1: An Easier Method..

This method of producing penny stoves builds on the YAPS Super simple mix where the internal can is inserted at an angle and rotated into place.

In the Scollop method we cut the side of the outer can to make insertion of the internal can even easier, bonus here is that taller penny stoves can be made.

View the images for a guide on how to cut the cans, I use scissors, no sanding or other forming is required.


*Make the Scollop fairly low in the can as it is easier to press home without fuss.

* Try to make the scollop cut 'clean' by cutting it in one motion, any burs may split the outside can.

Step 2: Insert Internal Can.

Once the two cans are cut, feed the internal (shorter) can into the outer can at an angle so it sits just below the base line of the scollop you have cut.

Now it is as easy as 1,2,3 when the internal can is straightened up and pressed home.

You may find the internal can will pressurize as there is an air lock, this is good, if so start by making the filler hole to release the locked air.

When the cans are pressed home trim with scissors and a blade to tidy up and finish by making the jet holes.


*Freshly used cans slide together easier as the drink residue acts as lubricant.

*Take your time pressing the cans so they are straight, pregressively cutting the excess outer can away makes this easier to do.

Step 3: Tripple Can and Double Scollop.

With this method you can layer cans to add a pot rest or pre burner and to strengthen the stove.

If a tall stove is desired, try an scollop the internal can as well as the outer can and place the scallops at 180 degrees to each other when assembling. This stops the internal can from bunching up and forming an crease which will cut or split the external can.

Do a little reading on other penny stove pages to get jet sizes, I have tried small holes with a needle, double top cans to make pressurizers, but have gone back to a larger size jet of ~0.8mm and 8-16 jets.


* If trippling up the cans an inside/outside/inside layer is stronger, the one shown here is inside/outside/outside and as it it was made in a rush to test the 'preburner' system the inner can is a little loose. You can always add a little superglue to hold in place (super2it).

    Thank you Thank you Thank you..

    I have just started making Alcohol stove using 'old school' methods = alot of %&*@! words and getting somewhat frustrated

    So I started to look around and saw this 'Scollop" which I thought was 'just another stove' with different hole setup.. And kept moving past it.. But still kept seeing it so I klicked on it...

    Needless to say now I don't care if I make one and it doesn't work the way I want.. I just make another one in no time at all..

    I have also found using a full can helps to keep things lined up and makes things even easyer....

    Again Thank you..

    Great, well done. Some days I can get them perfect no problem, others I will trash a whole bad of cans and get nowhere. Larger keg cans are harder to do and the small diameter ones go easily. Patience is a virtue.
