How to you clean or make a tiny hole?
Butane gizmo. Got it at a yard sale. Not clear it ever worked.
Is full of Butane. The orifice is two concentric brass parts screwed together with a tiny metal disk in between. Disc is very thin and about .150 diameter. Has a TINY hole for the orifice. 50X microscope is the best I had handy. Can tell there maybe was a hole..maybe... How can I clean or ream such a tiny hole? How did they manufacture it in the first place? I'm guessing that the hole has to be very symmetrical so the jet of gas goes down the center of the tube that mixes the air. Not worth fixing, but could be a learning exercise. |

Not sure just how tiny you need , but I had some that were so small they'd break if you breathed hard on them . Takes a very accurate machine to use 'em . -- Snag |

Think of a stranded wire - use one wire as a push / cut - Make a D
shaped cutter and see if it will cut/clean. Martin On 5/22/2015 9:31 PM, mike wrote: Butane gizmo. Got it at a yard sale. Not clear it ever worked. Is full of Butane.

Or, paint it with glue that doesn't stick to brass, then peel that off when dry, and hope it pulls the clog out. Laser, EDM, or #80 drill are all kinda standard. Perhaps also chemical etching. One cute way, is to stack a dozen pieces of shim, and poke 'em with a needle. Then look at the top one. If the hole is too big, look at the second... and so on. |

In days gone by we had (there is still one in my workshop) a device called a PRIMUS PRICKER for just that job in Primus kerosene stoves. They consist of a short piece of fine wire crimped in a cheap tin plate handle :-Z -- John G Sydney. |

(Vodka works) Avoid sticking anything through itty bitty holes to avoid making itty bitty burrs that can be a big problem. Your local jewelry store can clean it. |

How did they manufacture it in the first place? I've wondered the same about the orifice in propane torches. They're made of brass and the holes is barely visible. A #80 drill bit is much much larger than those holes. |

A #80 drill bit is much much larger than those holes. I do not know, but one way would be to put a aluminum wire inside a brass tube. Then draw the brass tube down in size, machine the brass to the right dimensions and then etch out the aluminum. They make 10 ma fuses in a similar way. Except for the fuses they put an platinum wire inside a copper tube. And etch the copper off the platinum. A 10 ma fuse is so thin, you can barely see it with a magnifying glass. Dan |
