How random, was just looking this up and figured I wouldn't really be able to find much info... then I clicked on this and was pleasantly surprised. Thanks, cheers 🍻

I was researching bushing recently, and from your video I learned that there are different types of bushing. Not many people are talking about it so thanks for the valuable video and your thoughts

Awesome video. Somehow this video didn’t pop up the first time I searched about bushings. I too thought the bushing rotating around the pivots before this. Thank you

Nice explanation. You got everything right, and I like how you covered the super basic stuff like what the outer diameter means. A lot of technical people struggle to connect that stuff because they forget its not common knowledge. Satisfying sound is determined by how well handles and blade transmit sound between each other. Most important tolerance for that is the diameter of the hole in the blade to the OD of the bushing, and then next is the tune on the bushing. Zen pin material & fit is also very important , but that's mostly on the makers and usually not an issue.

even tho I already know the function of bushings and how to tune them this video is insanely helpful and awesome!

14:43 That sound is caused by vibration. Metal is an element that’s quite easy to get in vibration because of there structure. All metals have a different frequency depending on there density, the mass and form of that object. There usually two kinds of sounds produced by the vibration for once the air that get moved from the vibration alone and second the sound that comes from metal touching and rubbing against each other because of the vibration. Cutouts effect that sound because the change the overall mass of that object and also direct how the air that carries the sound waves can move. Tolerances in the pivot effect that sound as well because they control how much space is to vibrate. High tolerances should cause an shorter and deeper sound while tight tolerances case an higher and longer ring. Just a guess but that’s probably why it is called tuning to size the bushings and remove play like instruments or tuning forks get tuned.

I was the 100th like 😎😌 i also subbed ty w video

Interesting point about the oil in a floating washer system. I think the main advantage of a floating washer system is that you can sand down the washers if you accidentally undersize the bushing. So you can’t mess up when you’re tuning a bushing. However, I’ve had real problems tuning floating washer systems. I always get one handle that ends up stuttering. I think it’s because the shitty clone washers have a burr on one side (or bent washers). Because, with a floating washer system, you have friction on both sides of the washer.

very nice video thank you

Thanks, great video!

What is the difference between bushings pivot system and regular washer pivot system?? 🤔

10:22 You are saying that the washers are getting thinner in two ways, one is by getting compressed this one is clear, but then you say that the second reason is that the washer is getting shaved off because of the friction with the blade, but we know even you said it earlier that they dont contact because the bushing is holding it away from the blade. So am I right and the second statement is not correct or I just dont get something?

I think the sound has a lot to do with cutouts in handes and how tight/loose the zen pins are. I think the cutouts determine the ring of a knife and then zens determine the bounce, but I’m also no expert lmao

So does that mean if my Balisong was perfectly tuned when it arrived and gets play and tap after flipping it for a while, if I can’t get it back to no tap and no play, I just need to replace the washers?

hey i was wondering how to find out the size of bushing needed? got a rep and they dont have it listed so im not sure if i should just hold them up to other ones or if theres a better way.
