Make a Mini FIRE PISTON On Lathe 

+Clark Eugene thanks Clark!

+420Alt thanks! Send me some pictures when you make it 💪

+Meep thanks, I will do best!

+Dural Metalurg definitely! thanks you

+BUK thanks Buk!

+Dark Horse Woodworking thanks man!

+freiermann7 glad you like it ;)

The bore is too loose 10mm with a 9 mm piston!!!!!!!

+play covers thanks !

thanks for suggestion! I tried that but the force was too high for the motor of the lathe to thread it. Maybe I should consider buying new set of taps and dies ;)

I think what he is referring to is to keep the workpiece chucked in the lathe and and have the tap or die mounted to the tailstock and manually rotate the lathe by hand while keeping slight pressure on the knob that advances the quill on the tailstock. The threads will cut perfectly considering the headstocl and tailstock are in relatively perfect alignment.

The air inside the piston is compressed and acts like a spring

+Josemar Santos Great spot ;) A smaller version yea :)

Maybe but no where near as much fun! Don’t be a kill joy! 🤣

How would you use the coal if it is buried inside a 12cm cylinder?

With great skill passed down through generations of engineers. It's not easy at all.

If I only had that kind of family heritage, I'd probably be trimming gold rods all day long.

+LookUpTV hi, you can buy an acrilic rod and pipe that matches the diameter. Check out @kingofrandom if you want to know how it is made :)

Many people DO have a lathe! Question is: Why don’t you? Have a good day! 😀👍

That's Overrated that's overrated ;)

+That's Overrated maybe in the future ;)

Make a video and show us how to do it...

the cost for the process of patenting designs is often not worth it as an indipendent craftsman. People are gonna come up with ideas all the time, to pretend that whatever idea you are thinking, is not being thought about by at least 7 people in the exact same moment, is pure ego. I'd say unless you're running a large scale production with billions to throw at lawyers etc, just let people make and sell whatever. No matter how original you think you are, you're not. Trust me I've been inventing stuff, only to find out they are not that special compared to existing things; making them uneligible for patent. Even if they were, I'd make more money making a video about it on youtube, than I would if I went through the patent making process Plus, there is an added value to the market. That is, since you're invention is in the public domain; people can be free to modify, improve, and therefore indirectly acting as your free outsource-R&D, that you can also further improve upon and sell from your own store.

Because he is using metric measurements millimeters!!!!!!

That's the whole point of prepping for when SHTF
