How, with common shop tools, do you hold pull rods while threading them without damaging them. A common vice will skin them up. I have used wood blocks in a vice, but they don't hold very well. I have a feeling someone has a method that is so simple I'm gonna feel dumb! |

First let me say I'm not a machinist, just a truck driving steel player with a decent grasp of logic and of the obvious.
I'd cut the threads before I cut to length, gripping it by any means available, but just beyond the intended cutoff point, so you're just damaging what will soon be waste. _________________ 2 pedal steels, a lapStrat, and an 8-string Dobro (and 3 ukes)

I have a couple machinist vices, drill press vices, whatever they're called with smooth jaws. I just tighten them up and give the handle a couple good hammer taps.
Grind or sand a taper on the end of the rod, use cutting oil and be patient backing off the die to relieve chips as necessary.
Sometimes, a rod will spin but it's no big deal to me. If a burr is left, I just sand and polish it out. |

If it already has the bend on the end,put the bend in the vise.That way it can't turn as you thread it. Thread slowly backing off each turn to release any chips that might try to get stuck in the threads as you cut them. Be sure to use some lubricant on the die to aid in cutting. _________________ Cops aren't paid much so I steel at night. |

Let me clarify about grinding a taper on the end of the rod. Just like a bullet end on the very end, like a sixteenth to an eighth of an inch just so the die is easier to start. |

Danny, I have the jaw's of my 4" vice lined with Ozite, the same stuff I cover the cases with.
The rods never slip or turn, and there's no damage to the rod.
I leave about a inch and a half sticking out to work with.
Good luck Pal, and get ole Jenkins down there and make him work, good luck with that too. _________________ Email: azpedalman@gmail.com

Get a piece of wood, say 3/4" square. Make the length the maximum you can get your drill through. Drill a hole through the length of the wood, roughly in the middle. Make it the same diameter as the rod.
Now with a hacksaw or junior hacksaw cut along the length on one side till you break into the hole.
You've now got a split bush which you can put in a vice and tighten hard with the rod in it.
The size of the wood isn't important as long as it works.
If this doesn't work find your Mother In Law and get her to hold the rod in her mouth. At least you'll get a bit of peace and quiet. |

I usually grab a couple blocks of wood and put them in a vice with the rod in between and tighten up the vice.
Not exactly rocket science. |

Copper jaws. I made these from scrap pipe, slit, flattened, cut and hammered onto the jaws. What I was taught at school 50 years ago. (These are not 50 years old, only about 20 )

I use regular old vice grips with a rag. Works great for me. _________________ Carter D10 8p/8k, Dekley S10 3p/4k C6 setup,Regal RD40 Dobro, Recording King Professional Dobro, NV400, NV112,Ibanez Gio guitar, Epiphone SG Special (open D slide guitar) . Playing for 54 years and still counting. |

Try wrapping it in a piece of an old inner tube then hold it with vice grips. the rubber shouldnt let it slip. |

Thanks guys. Looks like I was pretty close with the wood blocks in the vice. I've been getting by with it, but figured you guys had better ways. Fred, I created another addict by sending Ray Jenkins some chilli pequin hot sauce. Now I'm either gonna have to send him seeds to raise his own or send him to hot sauce annomous.. |

I have a set of these. Have not done exactly what you are attempting but they work for similar operations. You can apply a lot of pressure without marking stock.

I use 1 1/2" aluminum angle stock cut to approximate length of the vise jaws to hold most parts. |

Fold a piece of emery cloth in half the length of vise jaws, pinch the emery with the rod inside, clamp firmly in the vise, thread it. No slip, no marks. Please let me know if anyone has an issue with this. |

Well..here is my 2 cents..I followed Tonys suggestion..cut a piece of pine 3/4 by 3/4 by two and 1/2 inches long..drilled a 1/8 inch hole down through the middle length wise..I use 1/8 inch aluminum rod threaded 5-40 for a MSA..rod comes from local weld shop..was $4.00 for 8 pieces..sorry...back to project..saw through length wise till you hit hole in middle..I used a coping saw, but had to widen the cut with a hacksaw to get I little wider kerf so it clamped down tighter..works fantastic..holds great and no way to scar rod!!!!! Oh did 8 rods with it!! _________________ Music is good for the soul..playing it is even better!

The main thing is to only turn the die about 1/8th, to 1/4th of a revolution, then back it off about the same, and go slow. USE CUTTING OIL, or regular oil frequently. You have to keep the die threads lubed. Same procedure when cutting threads on regular pipe, or bigger rods.

Jerry is very correct..DO NOT forget to do that when threading the rod..will save you a lot of work and frustration and for me a big ole blister on my thumb. _________________ Music is good for the soul..playing it is even better!
