By the way Chris, in case it didn't come across, I really appreciated your reminding me of this, and you have definitely inspired me to do something about it, as I did back when I was a Boy Scout, and first heard of this. It was absolutely amazing to me then, both the method, and the fact it was discovered/invented long before writing, and that it is so easy to replicate. This is one I'm doing today. :lol: I can't tell you how much I will be enjoying it over the next few weeks. :bow: :beer: Cheers, Jack |

Nice one madjack - I`m pleased that is has reminded you. Like you, I was totally blown away by this lighting a solid fuel and being first used many years I expect before they knew how it was actually working. I look forward to seeing some of your fire piston build log pictures!! Chris |

Time to revive an old thread! I have been interested in these things for a couple of years but have been struggling to come up with bore dimensions to make it easier to light. After seing one on Chris' website it rekindled my enthusiasm. I have tried many different bore diameters and lengths and have eventually found something that works without too much force and is reliable. I know! :worthless: This is both parts And this is the O ring seal, you will notice a wee dent and think to youself "careless" But there is a reason it is there, I was finding it pretty difficult to change the O rings and so knocked a small dent in it to allow me to get a pointy thing in and underneath it. You will also notice that instead of using the normal recess for holding the tinder/charcloth I have drilled through and then slotted the top away. This holds the tinder better and also gives a much larger surface area to be lit. For such ancient and supposedly primative technology it works a treat, I can get a fire lit almost every time. It was seemingly discovered by explorers in the 1850's and is thought to have been around for as long as people have been using blow guns for hunting. They seem to think that the hunters noticed their blow sticks getting hot in use and a lightbulb, or star in this case, was switched on in someones head. The truth is that nobody will ever know where they came from but they sure are pretty clever.

Nice going Daz!! Glad it worked for you. Just curious, how did you go about cutting a straight bore for the cylinder. It is so long and narrow...! |

I have a long 8mm reamer and long drill for it as well .........I see a mini project coming up as there is some brass and stainless floating about in my cupboard that wants to be turned into something ATB Michael |
