Turning darts(dartboard type, not blowgun type)
I'd like to try and turn some single-piece darts on my lathe using some
SS rod. The turning should not be a problem but I need to know how to cut the 4 grooves in the flight(plastic "wings") end. Any ideas? Rich |

Take a square block, drill a hole in the end to accept the dart. Use a
setscrew to keep the dart from turning. carefully cut the groves with a small bandsaw blade. "eyeclinic" wrote in message ...

Rich Well Rich, it depends on what kind of tooling you have and what you want to buy. You can mount a slitting saw in the chuck in your lathe and a milling setup on the lathe crosslide. But I don't know what kind of tools you have so that answer may mean little. For a cheap solution buy a jeweler's saw. These use very fine blades. Buy a dozen-they're cheap. Use cutting oil. Make sure the work is supported while sawing. Make sure the saw blade thickness will work with your flights. ERS |

Rich Depending on your equipment, the ideal way would be to use a slitting saw in an indexer attachment, on a milling machine. A minimill would do it, as would a $30 indexer with a collet to match the dart body. - - Rex Burkheimer |

Are there jeweler's saws or slitting saws that small? |

Are there jeweler's saws or slitting saws that small? I slit mine with a .015 saw (thinist I had)..then swaged em down a bit with an over mandrel ..which was nothing more than a chunk of round stock with a hole drilled in it a couple thous smaller than the od of the shaft. I used bronze for the bodies. Some odd stuff I had kicking around. No idea of the composition. Finally wound up busting off the shafts over the years, drilled and tapped for commercial ones later on. Came out to about 18gr, soft point for bar darts. Not much steel darts around here.

Turning darts(dartboard type, not blowgun type)
I just happedn to have a dartboard in the shop. I have two sets here. One
has a tail piece with 4 wires stuck in the back.040" dia. There's a piece of plastic tube over the wires in front of the flights. That keeps the wires tight together. The other ones have an aluminum tail piece threaded in the dart with the slots in it. This part is available for replacement at dart shops. The slot is pretty thin.

Wouldn't you be better off threading the body for standard shafts? You're
going to ruin the shafts anyway, they're expendable. I think there are two standard threads. Stainless isn't dense enough, use tungsten or depleted uranium. "eyeclinic" wrote in message ...

Also, you probably want to make them out of tungsten, for its density. 2nd choice is brass. I made one for a guy years ago, to replace a lost one from a set he loved. matched it for weight and rough end to end balance. I don't think it was pure tungsten, but I honestly can't remember |

I don't think it was pure tungsten, but I honestly can't remember Actually, having seen many,many darts that suffered the "Robin Hood" effect, I think the problem is that the flight holder ends are cut perpendicular to the shaft axis, leaving a nice flat surface to impact with the next dart tip. Second, most people sharpen their dart tips increasing the possibility of the RH scenario. With the common bristle boards, sharp dart tips are rarely necessary. I plan to round over the flight holders and intentionally blunt the dart tips. |

They get dinged up hitting the metal. |

Do it before turning the final diameter. Anyway..thats how I made my several sets. Gunner "Pax Americana is a philosophy. Hardly an empire.
