Tonteldoos and fire piston
Posted: 18 Jul 2017 20:20
My whole life I have enjoyed working with my hands and making things. Lately I became intrigued by the Tonteldoos as used by our forefathers. After a couple of weeks of trail and error I am capable of starting a fire like the Voortrekkers did.
In my reading and research I came upon the term fire piston. As I have never heard of this it got my attention. There are a lot of you tube videos on the fire piston.
True to my nature I had to make one that work. Whenever I make something I always look at what scrap I have on hand. Then it struck me, I have two shot Patrol bonnet struts. After some time on the lathe I got it to work today. I first tried to use the tube and existing seal of the bonnet strut. I could not get the needed compression. I then machined a groove for an o-ring in the existing seal. Still the needed compression eluded me. My next idea was to machine a brass plug with a tight fit.. This worked. Next I would like to machine the brass plug to a smaller diameter an fit two o-rings.
I would like to make some changes to the current prototype when time allow. I will update this post with future improvements.
Now I can start a fire with steel and flint as well as a fire piston.
As a diesel fanatic I find it fascinating to be able to start a fire with the same principle that a diesel engine operate on.
