    Hi Mike,
    Nice methods if no lathe available. Another way to keep even spacing is to wind two lengths of wire together, and after anchoring the ends of one of the wires, unwind the second. Stay safe. WJ3U

      @@Boba-Fett-GS1150EzHi Ken,
      I like the idea of the weed eater line. You can select the diameter to give the needed spacing for the wire and as you say no need to remove it. :-) WJ3U

      Don, you bet me to it, If you wind a line from a washing line along with the wire you are winding, then unwind the washing line, good thing about washing line, it come in various thicknesses.

    Nice video Mike, bravo! The Master on lathe Bryan,old school!!! I think still the best, nice outlook and quality made coil for long time of use is that one on lathe made...👍

    I didn't catch it but with the lathe, how many TPI (turns per inch) did you have him do?

    I have a mobile/portable set up and I was wondering if it was possible to build a coil that would be useful on vhf, I could use a coil and an integrated balin, I am a machinist so I can wind pretty epic coils. I just don’t understand them. Lol 200 meters per coil then stack them together it looks like 1000mm or 39.37 in coil would be doable.

    How can I re-compute turns for a 4" form? I have two coils already made and I want to know if they are sufficient. Thanks!

    Another good one Mate. What would be the difference if rather than use the 5mm spacing, I just butt the cable to the previous rotation?

    • @internaut5610
      @internaut5610 4 года назад +1

      I'm guessing a higher Q factor, lower resonant frequency, greater reaction to rain or metal - but don't quote me... 🤔

      @@internaut5610 That would make sense, I built a coil like that recently for EFHW for 80mts and the bandwidth was quite small. I might try more of a distance between the coils to see if widens a bit. Thanks.

    Great stuff Mike, you can also use castellated grommet strips. what do you use to measure the inductance? 2E0UDB

    Mike do you know if the DX 10 wire is sold in the USA? It looks like its really good for wire antennas and ground radials. really like the your videos.. N6ZN

    Mike, thanks for sharing these techniques for making the coils. After winding, should you do anything to bind the wire in place for the long term? LCARA Ham Radio

    Don’t let your shop teacher catch you leaving the chuck key in the Chuck with the machine running.
    I’ve seen a few tossed across the shop when the machine was engaged.
    We were taught the only time you can take your hands off the key is when it’s out of the Chuck.

    Hi Mike, There Is ANother Method, Just Wind Up Two Wires And At The End Just Remove One, The Spacing Will be Perfect
