I just finished making my second penny stove from the new aluminum bud bottles. They take a while and a good bit of fuel to prime. But it does make a strong stove. I had a Sunkist can blow out (rip in side) in i=the installing of my burner. With the bottle the sides are thicker so the sides just spread. Any one have a problem with small explosions with the penny stove. I had the al bottle penny stove pop twice and I had my Sunkist penny pop on first use. Wondering what would cause this problem or is it just the operator.

I have many, many alky stoves and have not had the blow out problem you describe. I have used methanol, ethanol, and a miture of alky and white gas. IMO, your blow ot problem is because there are not enough holes (jets) for the alky to escape form the stove. The alky vaporizes due to the heat from the flame. If too much vaporizes and can not get out the holes... POW..there goes your stove.

I actually had the burner pop out when I first lit my Sunkist penny. It Blows up kind of when I first light the primer in the top of the burner with the penny in place. Sorry I should have specified. The blowout I got was not while burning. I was replacing the burner and when pushing down the cup tore( hinch a blow out). I think with the bottle penny I will have to use a primer cup. Never thought of this but it might work.

Wow! Are you using only alcohol for fuel, or trying some other fuel or a mixture to get better performance? Only alcohol should ever be used in such a stove. I have made many stoves, several different designs, all with lightweight cans and have never had one pop or blow out. Give some details - What do you use for fuel, what is your proceedure for filling, lighting, and using the stove?

I should have never said blow out. Looks like ya' ll think the can blew up or some thing. As I said above the blow out was a rip in the can when I put it together. The poping is the problem. I use heet. I fill my penny with 1 oz fuel. Then I use 1/8 oz on top burner with penny in place. I had 3 stoves pop like this on the first test. After that they pop no more. When I say pop I mean hop up like a small explosion. The first time this happened to me it blew the burner out of the cup.

My first homemade stoves were photons. When you forget to put the filler screw back in, they "POP" when you light them. Happened to me twice, both times when too tired to think straight!

yes, yes. lol, this has happened to me too. i think alittle pressure builds up when you cover the hole with the penny. does a great job at startling the crap out of me.

jazilla,
Yep, I had a penny stove pop and spray flaming alcohol around the kitchen. Melted the front of my microwave. Unfun. The reason was the holes were too large and the flame was able to ignite the air/fuel mixture remaining in the stove. Smaller holes fixed it.
