Re: Off Topic Question for the old-timers
开云体育Jim,Not the same thing as the ferrule you are referring to.? The one you are talking about is solid brass and used in a compression fitting.? These are sintered bronze and used as bearings in small electric motors.? They are porous so oil can soak into them to lubricate the shaft. Bruce -------- Original Message --------
I don’t think I’ve ever replied to anyone on this group before as I’m mostly a lurker ( no longer own an Atlas lathe). but I’ve always called what you’ve pictured a ‘ ferrule’. ?About half of the ones I’ve encountered have been made of plastic and half made of brass, usually the brass ones are frequently found iin plumbing tline fittings. |

Plastic may not be a good alternative I am afraid the shaft may bond to the plastic when it gets hot.

Bill,Really, these things are not rocket science. They are a set of centerless-ground rods of specific diameters, and a paper chart. (Or, you can do it with a simple equation.) As long as the rods are accurate on diameter, there just isn't that much to it, and you can check the diameters with the same mike you use to measure the thread if in doubt. If your threads are coming out rough, then you may need to make a few measurements at different spots and average. Some tweaking of speeds, number of threading passes and tool geometry may help the finish of the threads. And, of course, certain mystery metal may never give nice threads. Jon |

Re: Internal Threading - Compound Setup
开云体育You buy or make a plug gauge with as nearly exactly the thread you need to mate to as you can manage. For a lathe chuck, a duplicate of the spindle.? For the one I made for my Atlas I was essentially copying one of my class projects, but 8 tpi instead of the 12 tpi they wanted. So I wound up cutting something like 3/4" of finished threads off because the Atlas spindle doesn't have an inch and a half long threaded nose. Until I made the 2-1/4x8tpi stub for my Heavy 10L it was the most perfect thing I've ever made on a machine tool. Personal best, not necessarily something a real machinist would be impressed by. My instructor said it was the best I'd done. Took several hours, as I was checking both of them frequently. Not something a job shop would approve of.?

How do you use thread wires on internal threads? Even if the wires are bent into a circle to fit inside the internal thread, you need an internal micrometer or a caliper with a blade anvils to measure the wires on a tangent. On regular calipers or micrometers, each anvil will be measuring on their two edges, so the measurement will be inaccurate on the small side. Please enlighten me. Regards, Ron Mattson

Re: Internal Threading - Compound Setup
Technically, to make thread gauges plural.? You need a go and a nogo if the thread really matters like a receiver. Save time and make them on the same bar, just use your cut off tool to separate them.? You will need to create a landing zone between the two threads though.? Sneaking up on the exact size for a gauge is time consuming and you will wish you had three arms. Charles

Re: Internal Threading - Compound Setup
开云体育Ron,Earlier in the thread it was discussed to make a plug test piece with external threads to be used to test fit the interactive threading.? The reference to using thread wires was referring to the plug test piece.? So the wires would be used on the external threads of the test piece.
