Penny Stove Construction Tips - Herbie BoyScout

This video shows construction tips used to create a Penny Ultralight Alcohol stove following Mark Jurey's instructions ( http://www.csun.edu/~mjurey/penny.html ). It took me a couple of attempts to figure out the easiest and fastest way to to measure, cut, and construct the penny stove, and wanted to share what I learned.

I built this stove and whenever i light it, the stove turns into a flamethrower. I epoxyd the stove around the edges, and there are still very big flames. The fuel rins out very fast.  What could be the problem? The seal of the penny? I really want this stove to work as i hear it is absolutely amazing at boiling water.

@GhillieNova Sorry - I've no idea why your stove has very big flames. There is no need for epoxy anywhere. I can only guess that either your jet holes are too big, or for some reason the penny and the 4 holes underneath it aren't venting correctly. You may want to make another and change the size of the jet holes, or even the number. I experimented many times with the original instructions until I got it to burn the way all of the other guides show.

@hpear3 i used the chart on your website, the one that tells you where to place the holes. I used a 1/8 drill bit i think, it is to bigger than a thumbtack.

@GhillieNova Yeah, the instructions call for 1/16" drill bit, not 1/8" - that's your problem, the jets are much too big.

[ajatkinson2004]

is that just a drill bit on the dremel tool or is it one of the sander type bit?

[hpear3]

@ajatkinson2004 Just a drill bit per Mark Jurey's instructions

Of course I find this awesome tutorial right after i shell out 25 bucks for a triangia. I see you have one in the background of your video. Do you like it much? I like it with no wind, but on a trip the other day I tried to stop and boil water in a windy parking lot and even after using a sleeping pad as a wind shield the water never reached boil with a full fuel load. Id say it was about 2 cups of water. I was also using a Sterno folding potstand/heatreflector.

My tip - rest a razor blade on the bottle cap risers to score the can instead of marking the line with a pen. When you have it scored it cuts very cleanly on the score line. Super straight cuts.

@hpear3 Well i dont remember the but i used, but it is about the side of a thumbtack or needle hole. Im guessing that is 1/16"? That is what i used for the holes and the flames still shoot really high.
