Tabletop Bowling: Improved Pins

Making good progress! A lot of you suggested magnets and I may try them at some point. But itd be tough to get the exact amount of attraction force i need, plus I would have to permanently alter the wood lane and it wouldnt be super easy to change if I epoxy magnets in. And pins would have a small amount of attraction to each other which isn’t similar to irl bowling #engineering #bowling #3dprinting #mechanicalengineering #stem

@@dannylumcreative Sorry to hijack this comment. Usually with miniature models, to make them seem physics accurate for the large scale you have to slowmo the video. It has to do with gravitational acceleration seemingly higher due to the "zoom" of the model. Basically, even tho the constant is the same for big and for small, you are zooming in on the small model, therefore the acceleration seems higher than it should be if it would be the big model. That effect may very well play role in the way you are trying to make the pins fall. They fall too fast.

[@Bread-AAAAAAAAAAA]

@@dannylumcreative make a small screen that measures your score based on the weight of the back part and where the pins are usually hit

The pin spacing makes it so that one of the most impressive things in bowling would be to take out just 6 and 9 or just the 4 and 8

Only in bowling is 292>300.

[@marthew1]

You should put magnets in the pins so that they don’t get knocked over too easily from the ball and shaking, plus it’ll be good for resetting them

[@Mozart380]

Seeing how much he values accuracy to a real bowling pin, i doubt this is what he wants.

[@idkonaname7462]

You could also maybe lower the mass if the ball or add weak magnets or something to the pins

[@Towelieeeeey.Bowling]

As a bowler, I've loved following this.

[@ThaRealWalrus]

I love this series, impatiently waiting for the end result here!

[@MrPotato.2]

you have to try putting magnets at the bottom of the pins and then magnets on the lane

[@drenz1523]

Doesn't that make his problem worse?

[@jurekmc]

​@@drenz1523No because he wants to have pins up, but with less weight so they can change and magnetism grows exponentially so a little diference in position can make the forces negligible

[@stephen1561]

Can distance the magnet further up inside the pin to make it weaker too. I wonder if each magnet strength would be consistent though

[@codythecodester715]

For ball return add strings to the top of the pins and have it pulled up and back down every time with a mechanism

[@demeter-the-great]

Hell yea, though I wonder if this would mess with the strike dynamics

[@erskisdam]

You can take a real pin, measure it, then after you characterize the formulas that correspond to its mass, center of mass, volume, plastic deformation, and whatever other variable that impacts the movement of the pin. You can then scale down the process by using adimensional numbers to downsize the pins by how they are supposed to behave instead of by size. Hope this help

[@samael4550]

Shows how much engineering went into the original pin/lane designs, you’re being met with likely a lot of the same issues those engineers faced when developing the originals, just obviously on a smaller scale, which means your solutions are gonna be a little different for the same exact problems, pretty cool.

[@erskisdam]

As long as the model replicates with sufficient accuracy the original process you should reach similar solutions, unless constricted by manufacture processes

[@HVLO-YT]

You should put magnets in the pins and the floor to make it easier to space and more resistant to vibrations

[@jazzscott4604]

The fact that the pins wobble is actually pretty realistic. Especially for brand new pins because they haven't been worn down. That's why older pins fall easier than newer pins

[@Booped_Ur_Snoot]

i actually get so excited when these pop up

[@BillyisThis]

Between weight height and distance the pins are made of a material that would absorb the impact of the ball! The plastic or whatever used in 3d would Create a different effect because the ball hitting them has a different hardness variance

[@paladinkhan]

I appreciate the attention to proper scaling

[@pineball43]

instead of weights may i suggest just putting weak magnets in the bases of the pins so they still can feel light when in midair but they have much better resistance when on the ground, make sure the magnets aren’t too strong though or else they could lock on to the other pins or other parts of the lane midair

[@fableagain]

Oh my gosh, this is genius

[@turtleshenanigans3954]

i found this series randomly but im excited to see where this goes

[@Sharkspartan6548]

Genuinely amazing. I want one

[@MerlijnandPingie]

I think this is amazing you should keep up the good work

[@marthastewwart]

People have said magnets. But i think you should make them ⅔ hollow, then fill with sand. Have a little hole at the top of the pins that allows you to fill it with sand. Have the area go 2/3 down like i said. Try using a very fine course sand and then a larger grit sand. See which works better. The size of the grains and how they lock together will determine balance. You can test different combinations of amounts of sand used and type of sand. Then you can add cotton to any of the hollow space you don't want to fill and to also keep the sand compacted.

[@TheDigitalInferno]

You should attach a string to the top of each pin and a board with holes above it so that when you want to set the pins back up you can pull on the strings, pull them into the hole (which matches with pin positions) and then lower them back down so set-up is easier after each strike. This method is used in quite a few bowling alleys!

[@TheDigitalInferno]

ignore me his idea is way cooler

[@thienkyo]

Hi, kool project, love it, a suggestion, hold the ball with 2 fingers, the thumb and middle finger, when throwing the ball, twist the fingers, this makes it spin while going, you can hook the ball.

[@tranquilisimo8774]

This might actually become a million dollar idea

[@thatjokerperson7062]

They already make pocket bowling lanes

[@Pokeplayz131]

@dannylumcreative you could possibly add magnets under the lane and in the pins to make the pins easier to set up, and to control how easy or hard it is to knock them over

[@Airflows666]

I cant wait to see the end product i really wanna make one but i dont have 3d peinted but i love the series

[@UnsolPhysics]

So their center of mass (and tip) is falling over the base, when you want the impact to cause the base and center of mass to swing out from underneath the tip. My unsolicited hypothesis is that you may actually want the friction with the ground to be to low to help that behavior. Also I suspect that yeeting the ball with more velocity so that the momentum transfer happens more quickly and violently may enable that behavior. Real lanes are slippy and they tend to really huck them suckers afterall.

[@Steamie1102]

Great series cant wait to see the sweep and the pin setter

[@dannylumcreative]

Those are gonna be fun to tackle for sure

[@Siph_Maned_Wolf]

Dude that is so sick! I wish I had that patience with my 3d printers.

[@l.c5396]

Best party game I've seen yet

[@user-hc1ty6mn4s]

I think magnets could be a good option or putting steel at the bottom of the pins and magnets on the ground this way it doesn’t change the center of gravity as much as the tungsten, but you still get heavier feeling pins.

[@burriter]

this is actually so amazing

[@dannylumcreative]

Thank u ❤️

[@greenaum]

For the pins, seeing those tungsten weights sparks an idea... Why not replace them with magnets? Then put a big magnet, or even electromagnet coils, underneath. You'd be augmenting gravity with magnetism, essentially you could set the "gravity" and thereby the effective weight of the pins. How keen they are to stay stood up. Then with just a knob and maybe a power transistor, you could control it.

[@ryanfierro4897]

If you want to mimic full-size bowling pins I’d recommend focusing on not only the center of mass but also the moment of inertia which will definitely be more tricky to get right

[@dannylumcreative]

This is a really good idea i def shouldve thought of that. Its been a while since dynamics for me lol

[@0xmigu]

This is such a cool project man

[@Monado.]

I'm attached to this, keep up the great work! :)

[@dannylumcreative]

Thanks monado!!

[@rustywolf-tcg]

I've not done any math for this idea, but if you gave the weight room to move vertically, it would resist wobble but allow the pin to have an easier time flying/rotating by adjusting the CG as its struck (if the point of impact is below the CG)

[@HelpMeBroFrr]

You should put a ball in the pin so it stays heavy bottom wise but when the pin gets hit the ball moves allowing it to move mid-air more

[@user-ir5os6gd1z]

you can try and move the weights inside closer to the top so wobbling would off set the center of mass more and fall over easier

[@EbrkpYtbs]

The best bowling version!

[@christiemartin7224]

Love your videos

[@dannylumcreative]

Appreciate that christie!

[@nickscraft_minecraft]

As a high school bowler, this is awesome!

[@Ready_Set_Boom]

Make the base metal and place electro magnets in the pin positions, so when you activate the magnet the pins will pop up in their designated spots (if close enough)

[@terramarc]

You should put a permanent colored marking for the pins locations because I’m pretty sure most bowling alleys have them anyway

[@jessevanderham9623]

You could make different "hot swappable" bases with different frictions to select different levels of difficulty

[@wooow8543]

Add small magnets to the base of the pins ans the alley to make it easier to set

[@loquatiousloquat]

If you know the exact shape of a pin, you could tune the density by varying how filled each layer is

[@bwayagnes]

Loving this series! 😍

[@dannylumcreative]

Thank u!!

[@itsmewasa]

thats why they have sand so the weight will shift and the top is smaller so theres always more sand/weight in the bottom

[@Structed-2]

Good attention to detail. Any other person would just call it quits.

[@KenerauntSquarePants]

This is so cool 😮

[@dannylumcreative]

Thank u!

[@H311O-Pineappl3]

You should sell these bc I would definitely buy one

[@proximTeaMine]

Increase the gravity and air drag and inertia. Basically use magnetism to create conceptual forces so they act close to the real ones. Have some weak magnets hold the pins and electromagnetic rail to imitante inertia through out the track. Different surface or materials could also work keep improving 👍

[@Apple_Beshy]

The first thing that came to my mind is Magnet, + it's easy to reset because it will just snap in place

[@aydengianes2515]

Knowing my self i would make the lane longer and get the smooth shiny wood and put oil on it so you can spin the marble

[@zwarpzies]

you should add the paint lines from the bowling lanes and dots under the pins too

[@dannylumcreative]

Def gonna do that!!

[@RAU_Bricks]

You maybe could put weak magnets in the pins to: 1. Make it easy to put the pins back. 2. A bit harder to get a strike

[@Bozoized]

Good pin spacing on the newer pins!

[@Bozoized]

Wait nvm the spacing is literally perfect 👌

[@dannylumcreative]

Thanks bozo ❤️

[@vitomarchino]

Sounds like you want both the right CG and a comparable moment of inertia about the CG. Maybe consider having a weight at the bottom and a smaller weight at the top so the CG is in the right spot and you get an increased moment of inertia

[@iso_2013]

You should build a string-style pinsetter for it

[@saagarrai4603]

You should put magnets on the bottom and on the pins to keep them upright

[@user-bq1iq8rn9z]

Bro needs to get hired somewhere

[@phoenixtutorials2675]

I love this series, keep it up ;)

[@dannylumcreative]

Thank u!!

[@ZelX-]

You should put a small survo and run a stabilizing program so the pins try their hardest to stay upright.

[@Yzerbruh]

Have you considered using _fluids_ as a weight? Maybe drill it out more so you can fill it with multiple cylinders filled with sand/buckshot/etc. that aren't fully filled so the centre of mass shifts when it falls over and you can adjust the distribution for fine tuning.

[@cameraproductions-en5fe]

make an automatic pin placer like the ones in bowling allys!

[@Cacti_Treeman]

If that doesn't work you could try putting magnets in the base and at the end of the lane so they stay upright when shook but fall when hit

[@LostSoulsParadoxicalDoctrine]

Have you thought about using more of a donut shape for the weight? If placed within the base, but not entirely too low, you should be able to get the spin, the balance, and still resist the bumps and tremors of the table. Few washers should work, if you can't find a better alternative. Tho I think they should be as secured in place as possible, otherwise they might begin to rattle after a few good games.

[@dannylumcreative]

Yeah ill def be trying something like this thats a good idea. Tungstens too expensive lol. The pins are like mostly where i want them but i think i can go a bit further to make them perfect

[@niandadave4208]

Make them magnetic that’s like an on and off feature so it doesn’t fall if you accidentally bump it

[@lukevaldez1426]

You should use string to automatically reset them plus stopping them from falling over due to vibration

[@Wrestlingswannn]

[@The_Sigma_42069]

Instead of waits you could put small magnets to keep them more stable. Just an idea but love your work!

[@10000_angry_bees]

You should try making the ball and pin act like how they did in that one CGI animation

[@deltajon4048]

You could add like a bit rice in each pin to make it stay standing up longer

[@supercrafter7586]

instead of having the tungsten weight in the bottom you can use a thin tungsten rod that goes almost all the way across the pin so that the center of gravity along the y axis doesn't change

[@deadfishyarou]

I’m pretty sure the whole point of the tungsten is to lower the center of mass

[@supercrafter7586]

​@@deadfishyaroulowering the center of gravity doesn't help much in what he was doing, it was about focusing the mass near the center to prevent wobbling, which doesn't require the center of mass being near the bottom

[@deadfishyarou]

@@supercrafter7586 Lowering the center of mass reduces wobbling. If you look at static rigid body mechanics, the locations of the center of mass and the contact point(s) are the only thing that matters. I recommend googling "stability and toppling". Focusing the mass towards the center does nothing. (except for lowering the angular inertia, which would actually make the wobbling slightly worse, though increasing the mass by adding a metal 'wick' would do the opposite)

[@Siyawn]

you should put a magnet below the pins so that it wont be affected by the vibration as much

[@TheBowlerYT]

Nice work

[@YelmutNoHelmet]

You should drill 3 small holes in the bowling ball for comedic affect

[@Toby0895]

I love this

[@Liwcay]

Lol using the tpu. The lanes I worked at we had a rubber like stickers we put down on the pin spots to cut down the pins sliding. Funny though I get you have to adjust for the vibration.

[@dannylumcreative]

Thats a cool idea i havent heard of

[@Low_Qualitizer]

To reset the pins automatically use like a motor and string or something to raise and put down the pins

[@PLUV1]

looks fun
