Guys here are a few pictures and thoughts on the Fire Piston

67035297.jpg


This piston is made by Jeff Wagner of www.firepistons.com. The material of the cylinder is Asian Water Buffalo and the piston itself is made from Cocobolo. The gasket is a cotton string similar to the kind found on parcels.

Pictured with it are some other items I own to give you a sense of scale.

In the forground are the tinder samples suppied by Jeff. Each comes in a small Zip Lock bag and are sufficient in quantity to start about 50 fires. Jeff also supplies extra gasket string and a well made instruction sheet for renewing the gasket and general tips on care and feeding.

Here we see a close up of the Oakum supplied. This will not last as long as the other things provided but it will last long enough to get you into the swing of starting fires.


When I first read an article in BCUK (Bush Craft U.K) I really had to get one. The wait unfortunately was 8 weeks! Jeff wrote ocasionally to let me know the ETA which did nothing to stop the impatience :D When it finally arrived I lingered for a while (But not that long) to admire the workmanship and then I was straight outside to give her a try. One the first go... 'Houston, we have ignition' :D From this moment on I was hooked.
Later on I read a 'user review' of the Piston that unfortunately gave it only 'Gadget' status. This was in part due to the frailty of the Char Cloth. The piston has a small recess that holds either the Tinder Fungus (http://www.chagatrade.ru/moreinfochaga.htm ) or Char Cloth ( http://www.bushcraftuk.co.uk/200/char_cloth.html )

Admittedly I had to agree that the Char cloth is a pain in the rump to get out (unlike the Tinder Fungus, which not only ignights the easiest it smells great too) of the piston without another 'pick' like tool, which, when its buring away and your fingers is not exactly ideal. Then, this weekend I was playing around with a Swedish firesteel and ignighting '0' grade steel wool when I thought it may be a good idea to take a small sample of steel wool, gently shred it and put in a small bit of Char Cloth. You then roll it up like a booger between finger and thumb and place it in the piston. Fist time it lights the cloth. Its easily removed as the steel wool holds it in place and it can be handles without too much care. Drop it into the tinder (Oakum in this case) a few puffs and its blazing away, marvelous.

With this discovery I think it puts the piston back into the realm of useful/worth consideration as an alternative fire starter (Read Jeffs page to understand the benefits over a naked flame) and out of the Gadget/Gizmo category. Tinder fungus may be hard and expensive to locate but Char cloth is made for next to nothing and one Brillo Pad sized 0000 steel wool would make at least 100 fires. As a project, I am looking to make a small die and press and manufacture them to fit exactly into the piston. I will post any findings as I make them.
 
I think fire pistons are the coolest fire starters out there. You've got a great example too. Thanks for the pics,

Temper,
Great write up and review. I have always wanted to try out a fire piston, but I keep spending my extra money on knives. ;)
 
That is an excellent device! I'll be getting some of those!
 
I guarantee you will be hooked the first time you pull out that piton and a little ember is smaoking away. I have done some more testing with the steel wool and charcloth. I have had a 100% success.
 
I can understand folks interested in primitive fire starting building their own fire bows and pistons and the like, but for the life of me, I do not understand how using a ready made modern version of a primitive fire starter can be a useful survival skill.

Just a few thoughts....it lights naturally occuring tinders including fungi, mullein pith, milkweed pod, and wood punk without the need for additional preparation. It works after being completely submerged in water and it works in strong wind. Just for fun, toss your favorite modern, instant flame device in a bucket of water along with a fire piston and proceed to actually make fire with a friend making as much artificial wind as possible - :D

rgkeller, Most of us would take some manufactured things with us, it really is a matter of being 'prepared', afterall a Swedish fire Steel is manufactured as are most of the things we use in our pursuit of skills. Would you say the same thing of a knife or are you a purist that would only use a flint tool?

ras, I got it from Cabelas about a month ago. I love brass (must have been born in the wrong century :D ) Its a heavy bugger though, but well made. I would advise on the Aluminium if you are going to carry it.

Jeff, I'm still loving this and the joy of starting a fire with it never diminishes. :D
 
Well, I am far from being a purist. I like things that are small, lightweight and effective and most of what I find that meet those criteria is modern stuff.

I can see the value of learning primitive skills, in case one is in a situation that does not match the gear on hand. But buying ready made primitive gear...?

Good for kicks I guess.

My ferrocerium rod works after being submerged and I don't have to worry about the gasket.
 
OK fair comment. How about if it was made from Titanium, weighed less than a couple of ounces and had a gasket that didnt require lube?

I can't think of a good analogy other than the fact we are still using diesel engines and even our nuke powered machines like ships still use steam.

I get what you are saying but personally feel this is a superb way of making a fire. I also like 'older' materials such as leather and brass.
 
I have been experimenting with making my own. I think that having one made by someone like Jeff with lots of experience may be an invaluable tool in the pursuit of acomplishing my goal. I'm looking at the site now and seriously considering making a purchase!
 
Jeff,
I have been experimenting making a fire piston out of plexiglass and viton O-rings. I have had limited sucess, only achieving a smoldering piece of tinder fungus a couple of times. I think I have too much compression/seal, it is very hard to "strike" the piston. I also don't know if the piston to chamber ratio is correct. Any advise? I just want to make my own and not start a business.

Bore dimensions seem quite forgiving within a reasonable range. I have made ignition in pistons between 2.5" - 3.5" inches in length and between 5/16" - 3/8" in diameter. With most acceptable tinders, a "strike" is usually not necessary. I can light wood punk using a push method where both piston and cylinder and suddenly shoved together. I find this method a lot easier on the palm.
 
i'm currently experimenting with a fire piston made from a drop forged printing press roller axel. i'm having a friend CNC machine the piston, complete with 3 mini "piston rings" made from steel to seal the chamber. friction of the rings will be prevented by a dab of moly grease. the bore part of the fire piston is 3/4" diameter and about 6" long. Inital tests of the piston before cutting the slots for the piston rings (the piston was a very snugfit at this point) by my buddy revealed a pressure of about 300 PSI when the piston was driven hard into the bore.... the entire steel block got hot!

i plan to make it so i can put the tinder in, assemble the piston and strike it hard and fast with the back of an ax.
