diy... fire piston

Recommended Posts

Guest kevin

materials needed: 3/4 in diameter brass nipple 4inches long(nipple= 4 inch pipe threaded on the ends), 3/4 in brass pipe cap, 1/2 in diameter bolt 5 in long, o-ring, pipe thread sealer(pipe dope, teflon tape)

 

tools needed : pliers, hacksaw.

 

first cut a groove into thee threaded end of your bolt all the way aroung, about 1/2 an in from the bottom, the groove needs to be about 1/8 in deep.

 

2nd: roll o-ring into groove.(o-ring should be sized so that when applied to the bolt it creates an air tight fit when inserted into the nipple)

 

3rd: apply pipe thread sealer to threads on one end of nipple and screw pipe cap onto that end.

 

4th: insert o-ring in first into nipple.( remember has to be air tight).

 

done. to use the piston to make a coal you will need to remove bolt and drop a small amount of char-cloth or "punky" wood into the nipple reinsert bolt and SLAM bolt to the bottom of the nipple. the air friction will raise the temp inside the nipple to 600 degrees causing the tinder to create a coal......dump coal on to more tinder and blow to life.

 

 

the reason i suggest brass is to decrease the weight of the piston....about any material will work as long as it is strong enough to with stand the pressure created.

 

p.s. leather can be shaped for use instead of using an o-ring.

    • Hey all, This is sort of cool (okay really cool) and maybe some of you have heard about it because it's been plastered over FOX and mentioned by POTUS as well as other conservative-leaning news people (Huckabee, Diamond/Silk, Candace Owens, Mark Levin, etc..) and politicians. #walkaway is a movement based mostly on social media. Started last year, by Brandon Straka (pronounced Strawk - like "straw" with a "k"). He's a former 2016 HRC-voting hair stylist, from NE, now in NYC, homosexual, liberal who began to question the MSM and what he was hearing. He got really frustrated as he began to do his own research. Anyway, after having his own awakening to the lies of MSM he had been following, he began an online testimonial campaign in which former liberals can post their #walkaway stories, written or video. Many are now on the "Trump Train." Many have simply left the Left. Still, others have always been non-Left and are members in support. The amazing thing is how many different people from all walks of life are beginning to wake up. Lots are not conservative on all issues, but all have a love for the USA and dislike the demonization of open political and social thinkers and speakers. This group gives solace to people scared to voice their conservative opinions or views for fear of negative professional or personal responses. It now has budding smaller groups in all 50 states and an online discussion group where people discuss current topics or issues (WITH no vitriol, gasp).  Here's the original video from Brandon.  www.youtube.com/watch?v=51UGcghHZsk This man, Brandon has a unique, stylish, well-articulated voice to help move people "in hiding" out into the open and not be silenced. Pretty much any video Brandon does is great. Here is the Facebook page: www.facebook.com/groups/OFFICIALwalkawaycampaign/ As I see fights erupt online, I simply leave #walkaway in the comments. Brandon has a goal of 1 million members! The liberal media has called this campaign "Russian Bots" and "paid actors." It's not!!!        
    • thanks to all who  have served or are serving our great country....243 years in the making....   Trump did a good job today thanking each branch of our military and a long time coming salute to the coast guard too....
    • I can imagine food prices going up this Fall or Winter. Corn is used for live stock feed, & us humans consume a lot of corn based products, as well as corn based biofuel. I’ve been keeping a watchful eye on the mid-west of America, which is flooded by water. Where corn  & other crops are normally grown there. Farmers are quite worried about this years growing season. Time to stock up on extra food if you can, if you haven’t already. Stack it high, stack it deep. Store the foods that you normally eat. What ever the  amount of food you’ve stored,  try to double it if possible. Better extra safe, than sorry.
