For such a homemade cigarette lighter, the author needed a little free time, a metal jar from under the drink,
not a big bolt with a nut,
and a spring from a ballpoint pen.
First of all, the author polished the bottom of the jar to a mirror state,
for this, he took a regular rag napkin and cut a piece from it and put it on the bottom of the jar.
Then he poured a little hot glue onto this piece of napkin.
Next, the author took a furniture bolt
and put it with a hat into the still not frozen hot melt glue,
and wrapped the edges of the napkin to the bolt.
Thus, he gave the glue in a napkin a form for polishing the bottom. (Here's a nozzle for a drill turned out by the author.)
Then I inserted this nozzle into the drill
and started polishing.
At the end of polishing, the author put an ordinary paper towel under this nozzle.
After the author polished the bottom, to the desired state. He drilled a hole in the bottom in the center (under the bolt.)
Then he put the spring from the handle on the bolt.
Further, the author separated the bottom of the can with a knife.
Using scissors, he leveled the edges.
I inserted a bolt with a spring into the hole of the finished reflector.
And fixed the bolt with a nut.
This is what an almost finished cigarette lighter looks like.
And at the end of this homemade, the author did not straighten the edge of the spring much (so that you could insert a cigarette.)
And in the end, the author checked everything, it works.
