304 forum posts 14 photos | I would like to learn how to use thread wires I’ve a set of PD wires machinery’s hand book lots of good intention but for the life of me I can’t seam to figure it out, I assume you can measure metric threads as well as imperial ? I ask as it will be mainly metric I’ll be using now I’ve change to a metric lathe, just because it’s eaisier . Alan.

304 forum posts 14 photos | Thanks Michael I’ve read through it but it doesn’t help me I’m afraid, to much for me to try and take in, I could do with an example of how you measure the thread from start to finish using the wires on a M12 Alan.

304 forum posts 14 photos | The penny’s drops when you take another look at what your doing, when measuring a metric thread with the wire method it helps if the constant you take away from your measurement is the metric one and not the imperial one 😡😡😡😡😡😡😡😡 you know that feeling when you feel like a complete dick, hope that’s the last one for a while. Thanks anyway Michael, Alan. |

![]() 1071 forum posts | Measuring threads with wires requires three hands and a good deal of manual dexterity. Dropped wires can hide for eternity in the chip pan. A much handier solution is thread triangles. http://www.fowlerprecision.com/Products/Thread-Gages/526033030.html I was fortunate some years ago to find thread mikes at decent prices. If you can afford them they are the best way to measure pitch diameters. |

These are what you need! I've got a spread sheet that works everything out if you put in the effective thread diameter. If you are interested, message me your email and I'll send it you.

7517 forum posts 20 photos | I’v got some older versions - a spring loaded coil which are for discrete threads. All Imperial - they are likely not made that way for many a year, so pre-metric offerings.. Have I used them regularly? - No! Only of use if one does not have a nut to trial fit. |

![]() 1071 forum posts | Michael G, No, my metrology lab is not in the kitchen. SWMBO will not permit metalworking tools in the house. I have a 24' x 30' shop in another county along with a 400 sq, ft. house. I assume the term chip pan refers to something in the kitchen in Brit-speak. Please enlighten me. What do you call the tray under the lathe that collects most of the swarf? I have learned quite a bit of the terminology that is used in the UK from this forum. I would like to learn more. |

Chip pan : **LINK** https://en.m.wikipedia.org/wiki/Chip_pan ... as opposed to swarf tray It's rather like bonnet vs hood, or boot vs trunk MichaelG.

304 forum posts 14 photos | The needing of three hands is a pain in the you know what when using thread wires, buts there’s another way if your interested, all I do is when I want to measure say an M12 thread I use an already made M12 piece of thread it holds the wires perfectly and you can sort of roll the wires with your thumb and finger if you see what I mean, it’s quit easy compaired to any other way I’ve seen, give it a go you may be surprised.
