    This was one of those moments when as soon as I understood how it worked I just had to take a step back. This is definitely one of those special clever ideas. One that is simple but highly effective.

    The power of differental is under utilized in so many ways ... Location, force, speed, electronics, hydraullics, etc..
    Nice practical use.
    And perhaps an even better demonstration of differental potential elegance in design.
    Very nicely done.

    Wow Adam. Amazing design and selections of parts.
    It takes a smart person to build something that does a specific job but it take a very smart person with tons of experience and a deep understanding about how things work and how things are made, to transform something very complex and expensive into something so simple and low cost. Congrats for the design.

    Excellent shortcut for getting ready-made differential threads. Love it! I usually end up with tapping an M12 x 0.5 mm and single-pointing a 0.4 or 0.45 mm pitch about the same diameter on the other end of a rod to get a 100 or 50 micron per turn effective rate, but never thought of using 3D printed supports/tensioners. Nice.

  • @InheritanceMachining

    This is such a clever and powerful design. Especially given most of the components are off the shelf parts. Probably like most people watching this, you've got my gears turning on how else this could be applicable. Great idea and thanks for sharing!

  • @quintinsmits
    @quintinsmits ปีที่แล้ว +3

    It breaks the 'no machining' rule, but it could be an interesting solution to the stability issue: the height setting on the Tripan toolpost uses a piece of spring steel in a slot milled perpendicular to the threads. It bows out a little bit so it gives some pressure on the mating threads.

    Combining off the shelf hardware with 3D printing is a great idea. I am not too sure though how easy it is to get these adapters over here in Europe but I think that an M10x1.5 to M8x1.25 adapter or even M14x2 to M12x1.75 is a fairly standard item.
    Just putting some thicker grease or copper-paste on the thread might reduce the jiggle and make it move a bit smoother.

    @gibsomperson 2 ปีที่แล้ว

    I just found your channel tonight and I'm beyond impressed with your innovative mind.
    An idea I had to give more stability, precision, and repeatability to the adjustment, and bear with my terminology as I am not a machinist by trade:
    A bar spring, such as the magazine release spring in a glock, held in place on one end in the upper mount, that interfaces with a inverted cycloid-tooth cog mounted as a collar around the hex of the thread adapter. The inverted cycloid geometry of the teeth should allow the bar spring to cycle between The bottom lands of the cog when enough torque is applied, while otherwise holding the thread adapter at relatively repeatable angles. The level of precision from this system could be tuned by increasing or decreasing the number of teeth on the cog.
    Thank you for this incredible library of information on machining; I will be diving into more of it throughout the week

    • @gibsomperson
      @gibsomperson 2 ปีที่แล้ว

      So I finally got around to testing this idea, and as I'm sure was obvious to some of the more experienced here, the inverse cycloid shape was a mistake. I ended up reshaping the detent to just be a sinewave and it works a treat

    Cleaver idea ! To get that precision "stickey" thread feel, split the male part of the thread lengthways and then stretch it open a little with a wedge the thread will then bind a little taking out all the back lash and also preventing it from moving with vibration but will still be easy to turn, have used this technique many times before

  • @Bob_Adkins
    @Bob_Adkins 2 ปีที่แล้ว

    An excellent way to get a fine adjustment is to use wedges with a very low angle in combination with a fine threaded screw. You can easily get as little as .001 movement per revolution. You can also use "differential" wedges for even finer control, but it's probably not necessary.

    This may be a horrible idea, but to stabilize the threads, how about some putty eraser. This is a clay-like/rubber substance that doesn't harden. Not sure how it responds to oil. It may dissolve.
    And if it doesn't work, you can still use the eraser to clear chips and oil from difficult to access holes and corners. I use it a lot for that.

Thanks. 6:31 - Interesting measuring device, shows two decimals. Simply just wow, it seems like this leveling jack is not "high" but rather "ultra" resolution, it seems to hold well down to 25 nanometers (0.000.001") accuracy. This could be further improved to hold down to < 10 nanometers, possible using anti-backlash nuts.

    Question for ya. A 1.25mm pitch takes 20.32 turns to move an inch. If one were to use a 1/4 20 pitch thread, would that not make the differential even smaller than an 18 pitch thread? In fact, as long as I use a 20 pitch thread and a 1.25mm pitch thread, I could put those thread pitches on a 1 inch diameter rod and make a very sturdy jack?
