• Re: What's just slightly smaller OD than 1/8" NPT thread????

    From dennis g@21:1/5 to All on Mon Apr 24 15:02:34 2023
    1/16" pipe thread is smaller , but it is uncommon

    however as THREADED PIPE CONNECTIONS ARE TAPERED , one should be able to run a pipe tap a little more into the threaded hole if what you have does not SCREW IN..

    IF THE WALL OF THE TUBE IS THICK ENOUGH , you should be able to run a pipe die onto the tube a little more making yhe end of the tube smaller.

    ----------------------------
    I don't see the context here, but to answer the question literally, the
    nominal OD of 1/8" pipe is 0.405". 10mm (0.394") and 3/8" (0.375") are
    slightly smaller standard sizes.

    This is useful if you make things from pipe: https://usaindustries.com/piping-isolation-testing-products/pipe-schedule-chart/

    (Schedule) 40 has the common wall thickness. The nominal size is a relic of weaker wrought iron pipe from the early 1800's and doesn't match any
    dimension of modern steel pipe.

    I was in line at an industrial supply store behind an inventor who was
    picking up 2" ID ball bearings he had ordered to go on 2" pipe, to support a solar tracking array. He was quite upset to discover that they didn't fit because the OD of 2" pipe is actually 2-3/8", and it isn't precisely round
    or accurately sized. I decided not to mention that I'm equipped to build inventors' ideas.

    I machined the thrust bearing on my tracking array to match the actual sizes
    of pipe.

    I forgot to mention lamp tubing, which has straight (not tapered) thread of 1/8" pipe size with a 3/8" OD. I just confirmed that it does thread part way into a 1/8" pipe coupler.

    There is no context because its a 10 year old zombie thread. Who knows.
    Maybe dpb is still looking for the answer.

    Well, just heard back from Mr Briggs and his cohort

    The drawing that I have of the part shows the thread specs as 3/8"-32

    3/8"-32 is the thread on an RF cable F connector.

    All the posts in this thread show in order on my reader. That's a
    direct quote from his last post in this thread.

    I have probably installed thousands of F connectors and I never knew the
    thread on them. I probably installed even more BNC connectors. I tried
    very hard not to have to install RJ45 connectors, but sometimes that was
    the only answer. (IP cameras)

    Be glad you weren't tasked with assembling Lemo and similar connectors
    invented by Swiss watchmakers. I got (and did) the jobs others gave up on.

    I learned the specs because I've had to make electrical connectors or
    tooling that were unavailable to buy, to solve some unusual repair or R&D problem. The hardest was for 0.001" x 0.005" (20x100 micron) gold IC bonding ribbon. Not only was it tiny and delicate, it had to pass 3GHz.

    Somewhat surprisingly I couldn't order the pin spanner for the microphone connector nut on a military Have Quick radio and had to have the shop
    machine one.

    The USB TV tuners for my laptops run quite hot so I turned finned heatsink disks that screw onto the F connector. https://www.amazon.com/Hauppauge-WinTV-DualHD-Tuner-Windows-1595/dp/B015IL0FIW It works directly with Win 7 Media Center to play, time shift and record
    free antenna HDTV. I solved my no-cable Internet problem with a $35 package
    of cellular phone and net from Boost Mobile.

    I used one of those for a while, the first one ran very hot; the
    second one, not so bad. Then I made the mistake of going to Windoze
    ten and discovered that sound is much slower than light - I had a very noticeable lag of the sound behind the video; so I nnstalled a TV as
    my second monitor.

    I have a 22" Vizio HDTV as the laptop's external monitor, with the video
    feed split to both. The Win 7 laptop is an older, thicker desktop
    replacement Dell D820 with a boot SSD and a second 1TB hard drive in the DVD drive compartment for recordings, and a USB3 Expresscard to save them to the archive at the full speed of the external drive, though not full USB3 speed.

    By substituting a D830 with 1680x1050 screen resolution I can display four
    PDF tax form or instruction pages simultaneously, while filling in my spreadsheet copies of the forms on this laptop and its 19" external monitor. They do all that I need and I hardly ever use my Win 10 Thinkpad.

    The HD screens are excellent for the complex display of digital radio: https://www.sdrplay.com/
