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!)

[@Joseph-Mullins]

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!

@@Joseph-Mullins Isn't the human body (and life in general) weird and amazing? Congratulations on your recovery!

[@Joseph-Mullins]

@@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.

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.

Wow bro your probably one of the coolest guys I know. What a great mind you have. Thank you for sharing this with us. Respect from Las Vegas NV USA

Stuff Made Here has some serious competition now for Most Dangerous Idea Made Real on the Internet now :D Very cool build, but I worried every time you fired that thing at your neighbor's fence about an errant shot going high and over the fence..

This is amazing. You're doing a _real_ engineering project, and your son is making genuine independent contributions. I did OK for myself, but I wish someone could have included me in projects like this at his age! If he decides to pursue a career in it, he'll be so far ahead. Plus, it's a neat project with a hint of danger, so it's super engaging. I hope you get 100 million views!

Its been a while but my dad got me into knife/ hawk throwing. Throw like a normal baseballs every 3 steps for a full rotation and if needed you can do a 1.5 step and throw by the blade. My best was 6 in a row at 35 steps but that was when i was a kid like 15 years ago. That machine is super impressive! Id wana see how far it can go!

Gosh dangit, I wasn't planning on going to college. Not for a career reasons anyway, but this video alone changed all of that. It made me realize I need to learn a lot more than I realized if I want to be able to make things to the level of quality and complexity that I want. Pretty sure you just accidently reoriented the direction of my life. For that I am grateful.

Wow. I will say this was my first video I know I could not have done without my engineering degree. So yeah, if that's your goal, physics and math is where it's at. Be sure to watch the behind the scenes video on my smaller channel BUILD2.

This is awesome! And the best part isn't even the knifes it's the bond between a father and son that is seen very little, and in todays world we need more of it!

[@JustTony72]

This is awesome. It's super exciting to see the patience and guidance your son is getting. Very inspiring and if only more class rooms could be like this we'd have a lot more interest in learning.

This is such a cool hobby with a kid.. Love every minute of it

[@redboone1509]

Love the warning sign on the side. Couldn't think of a better machine for that sign or a better sign for that machine.

[@QuintBUILDs]

😂

[@overthought2098]

Awesome and I love the fact that it's you and your son. When he gets older he's going to be an amazing engineer. More so then he already is. Keep up the great work and content. 👍

[@gumby5068]

This video feels so homebrew and yet also so professional it’s amazing!

[@arthurmorrow9709]

Now this is some real awesome quality content. You two are geniuses.

[@trevorjames5493]

Having a dad to hangout with looks like it would be pretty awesome. Cool video

[@acquasmoke7729]

I’m so jealous of this build. When I was a junior in high school I thought of a gun that shoots sprockets using 2 chains the way yours is set up. I always thought of random stuff to make

[@slendykidslenderkid3185]

I love how much fun you guys are having with this making me wish I had a machine like that to play with

[@sabyasachimaji344]

I never saw such effort in KZbin. Salute❤️❤️❤️❤️

[@fennten8338]

honestly the best part is the genuine father son bonding
