      Trick shot idea: Extinguish a lit candle with a thrown knife without knocking it over.
      (Thinking up trick shot ideas is difficult; most of my ideas ended up being just picking targets, not actual trick shots. Good luck!)

      but instead of all that good stuff that's important to kids he ended up in jail and then committed suicide 10 years ago. i didn't know anything good about him or that he was into engineering and programming until we had to sort through his stuff. I was learning programming and engineering at that time so it was surprising to find out but also made it a little more depressing.

  • @Joseph-Mullins
    @Joseph-Mullins Před rokem +22

    Its the mass.
    To be honest if you find the center of gravity of the knife, you can quite quickly work out the distance that works for a knife to stick at 1:1 ratio of foreweight to rearweight.
    Once you figure out that distance, you can take a step back and modulate your starting grip (which is mostly determined by thumb fore and mid fingers) FORWARD on the knife to slow the spin.
    Starting grips modulated further back give it a quicker rotation and thus can be used at closer distances.
    Then through practice you can find the ratio of shoulder length paces forward = x finger lengths backward (from center of gravity) ((faster spin))
    or shoulder length paces backward = x finger lengths forward (from center of gravity) ((slower spin))
    Once you get a feel for these ratios, you can generally calculate the pace quantity to your target, and the ideal grip to accomplish the required number of spins to stick it to your target (with a small variable of arm velocity to determine how deep youre trying to penetrate.. when throwing by the blade, you can accomplish a half spin stick or a spin and a half stick, depending on the distance to the target is, you can actually tweak your throws very accurately through these parameters.
    I got very good at knife throwing with 9, 10, and 12 inch cold steel throwing knives.
    I find its actually best to practice with at least 3 of each size, because you dont have to retrieve your knife and recount paces or even move from your original position. But even better, to use 2 or 3 different length knives as well. Smaller knives are much more tricky and sensitive to adjustment, making a great challenge for intermediate throwers.
    I got to the point where i could teach a person, brand new to throwing, the correct ear-to-extended arm movement, and then mentally calculate how many fingerwidths back or forward from center of gravity they should take their starting grip with, and even a complete novice to throwing would stick at least one knife in under 3 tries.. its a lot of fun and a great way to blow of steam or have friendly competition.
    It really made me smile to see your contraption and to be honest i havent thrown much in years since i experienced a rough bout of radial nerve palsy a few years back.. if I had your invention I could have coped alot better while my arm was down! It pains me just thinking about the emotions that were running rampant through my head during that dark and lonely quarter... thank you for your video, and the cherry on top is seeing you accomplish all this with your son! Congratulations on your awesome idea!!! I might just have to make a few throwing videos now!

      @@TangoTribeAustin if im honest i believe it is 100% spiritual like everything else, especially since learning deliverance ministry when I found out an ex of mine was possessed (literally). Those demons laughed at me and ran circles around me until I realized I had to command them in the name of Jesus! Then they started coming right out! We thought my house was "haunted" until one of the orbs became a full silhouette standing between me and her. I said it had to leave if it had ill intent, and felt the presence grow hostile in the room, and the spirit "run" right at me. I started provoking it using religion (cuz I figured it was demonic) speaking about the blood of Jesus defeating it, and suddenly a different voice came out of her and she began to mock-repeat what I was saying to scare me because it was getting annoyed and worried I might dig deeper.. didnt work though I realized she was possessed took her upstairs and starting trying to cast it out. The "blood of Jesus" angers them royally, and breaks most of their power if you know how to apply it, (I didnt) the NAME (character) of Jesus is what makes them tremble and obey. That was a year and 8 months after the palsy, and looking back I know what caused it, and am surprised I wouldnt put those final two pieces of the spiritual puzzle together before then. I prayed for the first time in a long time, crying and asking for forgiveness and healing like never before... that day I was fully healed. My wrist would extend from then on with no problems where before i could only barely keep it from dropping if I held it a certain way and strained my brain as much as possible. It was like my brain was shorted out, and it was... my point is stuff only exists in the physical because it existed first in the spirit, and the spirit realm is more vast and governed than our own.. the spirit is how we perceive and make sense of things, the soul is how our spirit interacts with our bodies, and our bodies are how our soul interacts with the physical. Things we do and see and believe in the physical can have a direct effect on our spirits, but Ill tell you one thing, the bible is the only weapon we have to fight off devils with power and authority using! They believe the word of God and tremble! Sabbath peace upon you and yours, in Jesus name.

    Me and my buddies made a circular saw blade launcher like 15 years ago We went more for power then anything else but we got it to the point where 6 in discs would almost disappear into a tree trunk With maybe an inch exposed I don't know what happened to it after he moved but if we could've designed a magazine for it to automatically feed discs the thing would've been quite the zombie apocalypse weapon

    Awesome video - v-squared is the reason why a thrown knife will stick, it's not rotational (rotation doesn't actually exist) it's just velocity. our arms are slow when stabbing, but throwing we can combine motions of limbs more effective to get faster.

    • @skepticalbadger
      @skepticalbadger Před rokem +1

      Call it what you want, if the blade doesn't spin, you can't align the point with the 'armor' to allow for penetration at this very low velocity.

    May I add: a skin of truck-bed-liner has a different mechanical strength, though its not comparable, its different from printing plastic in tensile strength, so, conceivably you can print a unit with fine dimensions and coat that sub-structure in Line-X to fill in the girth; giving it 3-D structural bones and surface-tensile-brute-strength to survive, the muscle, you've designed so well.

  • @educationalpurposesmostly

    A a fellow inventor and engineer, I feel your pain of breaking stuff mid project. I also feel your joy of watching your invention pay off. This project looked like you got your fair share of both of these. I do have a suggestion for you: Use FDM for your 3D printed parts, resin is much more brittle and some FDM materials would not have broken when the machine failed. Some strong FDM materials are Carbon Fiber Nylon and ABS. If you do get a FDM printer I suggest the Original Prusa i3 MK3S or the Bambu Lab X1 Carbon. Also linear rails could be a nice addition for guides on the thrower.

    I loved watching the machining of the knives. When the sad piano music started and the solenoid had issues letting go, this turned into a "will it release too late and throw backwards" nail biter. Watching this put a big smile on my face. In recent years I've found more and more creative ways to use my nerd knowledge for fun and dangerous hobbies.

  • @davidantweiler4729
    @davidantweiler4729 Před rokem +1

    Really cool stuff. My guess on why thrown knifes stick easier would be that the longer lever and resulting higher speed when throwing, which could lead to inertia keeping the force from being dissipated oder a larger area. Like the difference between a push and a punch of equivalent force. Looking forward to the followup.

  • @MCSEknight
    @MCSEknight Před rokem +21

    This is Amazing!! I'd be interested to see your findings on the kinetic energy / knife penetration questions.
    I grew up throwing knives rotational style. One day I was amazed to see that there were world champion knife throwers who throw "No Spin".
    I had the same questions and thoughts you did regarding knife penetration into the targets, but in my case it was in relation to throwing style (spin vs no-spin). My initial thought was that rotational throwing had much more penetration into targets because of the rotation. My rational was that the rotation somehow added more kinetic energy when the point made contact. Thinking about that now is akin to pushing on your dashboard to try and make your car move faster. The reference energy in that case cannot be inside the car, it's on the wheels. Similarly, a flying and spinning knife's reference point is it's flight speed and mass, not necessarily how fast/slow it spins.
    Anyway, after months of learning the No Spin style, it was interesting to learn that No Spin has just as much penetration power as rotational knife throwing. I'm no scientist, but the only thing I can think of is classical Newtonian Physics of action/reaction and motion.
    Jabbing a knife into wood with your hand (stabbing motion) - measure arm travel and speed. Factor into that, that you don't want to swing as hard as you can because your hand can slip around the blade when contact is made - adding a nasty cut to, enough of a strike that you could break your hand. You tend to hold back some power because you instinctively know your physical limitations when hitting hard objects with your hands.
    Compare that to a knife throw, where your arm travel is twice the distance, give or take, and with much more power by the time you release the blade. More power + faster release = a Lot of kinetic energy, and a lot of knife penetration into target.
    Really cool video, and thanks for sharing!!

    • @Kronin87
      @Kronin87 Před rokem +3

      Great comment. I'm a knife/kunai thrower myself, both spin and no-spin techniques.
      Your answer to the final question of the video is correct.
      When you try to manually stick a knife in a solid target, you will instinctively hold back to not injured yourself, and so the motion is far more contained than when you swing to grow from a distance. Even if you swing light. Is that simple.
      If you try to match the speed and force of the "far trowing", when you manually stick the knife from close, by putting extra care in grip and trying not to put much force after the impact, you will obtain similar result as a normal trow.

    I have memories of hitting my first bullseye with an arrow, at 11 years old. My godfather is one hell of an archer, and he spent most of one summer teaching me how to handle a bow. That moment at 8 and a half minutes? Thats exactly how i remember it. Heck... i vividly remember his face splitting grin the second time i hit the target dead on!
    That was 26 years ago. And i remember everything about it. Your kid is going to remember that "Thunk!" For a long, long while.
    Keep at it!
