They’re usually funded by either the city or whatever neighborhood they put it in, so the old heads just hire whatever “architect” who just copy and paste what they think a skatepark is supposed to look like. Still better than nothing, but yk.
@@boss_tum I got you. I've only had one truck actually break on the axle and chalked it up as a defect. I haven't heard of people actually having problems with that but then again where I live you can really only skate 4 months out of the year.
That's not chemistry. That's physics. The bottom of the truck is aluminum. The axles are steel. It's not the coefficient of friction, it's the hardness of the material. There might even be less friction, can't say for sure. But aluminum corners will cut into aluminum metal. You can you can cut almost anything with an abrasive.
Although it is technically physics, the scientific concepts behind this are something that would typically be taught in chemistry courses and not physics courses. Much of the discipline of chemistry is technically physics. Source: I have a BS in Chemistry & Physics
man didnt do his research due to PHYSICS aluminum scraping against aluminum does have a higher coefficient of friction. meaning in simple terms, much more friction
This made you sound ignorant tbh because anyone who knows anything about physics and chemistry knows they are very closely related and many times phenomena in physics are caused by chemical properties.
It's a molecular level interaction (specifically intermolecular forces), which, although not technically chemistry, is something that is taught in chemistry courses and not physics courses.
@@LunaticTheCat i learned it in physics. But based upon the type of level is chemistry in a sense of the molecular forces but based upon the interaction and how it is applied becomes physics. At a certain point chem and phys overlap a bit
I build steel rails. Can confirm. Most is sch. 40 and doesn’t get galvanized unless it’s ordered as such. We often use sch. 80 on the legs of rails. Same diameter as the 40 but thicker toob.
I remember a dude trying to grind something made from aluminum, and I can't exactly remember what it was cause that shit was back in like 2005, and he was so confident that he could do it only to eat shit on his first try🤣 pissed him off so much that he just gave away his board to one of us kids and we never saw him again
Bmx riders love aluminum as well our issue is that it dents easy so if your trying to sesh a rail you get like 3-4 grinds b4 you have a dent in the rail somewhere that is going to bounce you off it
Schedule 40 is a grade for pipe thickness. Most coping is made of pipe either a53 or a106 grade steel. Typically using a 1-3/4” pipe that is sch 40. Flat rails are typically a 44w steel. For anyone wondering that’s what to ask for.
I worked at a fence company for awhile, used a bunch of scrap pieces to build rails.. schedule 40 is legit lol, grinds so well. For those who wanna build their own rails, schedule 20 is a little cheaper and works just as well!
If I'm not wrong it's called galling and it's basically when the same material is rubbed together and tries to weld. A shelf on the ISS actually had to be cut out because a bolt was the same material as the threads it was going into
There was a brand of steel trucks that made a point of using steel vs aluminum. They where heavy and kinda expensive. I forget what they where called it was so long ago.
So basically, if I am a local government who wants to screw with skateboarders, coating every surface I can think of in aluminum is a deterrent that wouldn't be noticed by most people.
Trying to relate to Jamie foy by comparing obstacles. Getting blasted from sticking on that out rail to then a half arse attempt of a kickflip smith on a small as ledge.
You know, I never realized just how realistic the movements in Skate 3 were until watching this video. Even the constantly looking like you're about to fall off. Skateboards are terrifying and I hate them.
how so? i understand forward motion friction and what not but wouldn't it actually be the base of the mineral compound first then in turn it dictates the physics?
Different kinds of aluminum. Ideally you'd want your ledge to be a a harder aluminum than your trucks. If the ledge is softer (or similar) then you stick.
Now I don’t know much about skateboarding but using aluminum for for grinding doesn’t sound like the greatest idea. Aluminum is pretty soft and I’ve seen it get worn down by much less.
Damn that kick flip smith at the end was clean af
Had those exact same words lol 🤙

I swear 99% of skateparks are designed by people who don’t understand skating at all
They’re usually funded by either the city or whatever neighborhood they put it in, so the old heads just hire whatever “architect” who just copy and paste what they think a skatepark is supposed to look like. Still better than nothing, but yk.
Not a lot of skateboarders go into city planning, and it's cheaper to grease rails than it is to replace them with tax dollars.
It’s probably because architecture takes a lot of brains and honestly, I feel like not many skateboarders have that going for them.
I always thought skating janky parks are more fun
@@Hobbs__ Dude, not a lot of people have brains,evidenced by you. so yeh not many skateboarders have brains, but thats normal
Thats why you get those titanium trucks, let's you grind brick
Ya at one arm and two legs each
@@brighamruud5090 how expensive do they get?
@@PewDiePower from what i can see it’s about $50 per truck
@@thelargest5131 Less than expected but still crazy
@@thelargest5131 that really not alot of money
the og tensor magnesium with solid axle and solid kingpin is my all time favorite truck
I've been looking into Mag Lights, how do you like your Tensors?
@@coliimusic don’t get anything hollow
@@boss_tum I haven't grinded much (started skating again after 12 years) but Thunder hollows ride great and even with an 8.5 I get tons of pop.

Skaters grinding to the rail of chemistry against alimuimn ledge across the friction through half pipe and continuing to controlling a new trick!
Aluminium......Al - u - min- ium 😁👍♥️
Not al - ooooo - min - num 😊
@@larryjimbob this comment didn’t even say either of those lol
@@lewisgray4202 No it didn't. They said alimuimn which isn't correct either 😁👍
@@larryjimbob my bad
There's a reason people soap rails like they're trying to get them ready for a date that's coming over lol
Soap? In my day they used wax. It became such a nuisance that the city built a skate part just so they would stop waxing all the edges on everything.
Someone make a skate park using only aluminum just to piss people off.
They'd still wax it up
someone make one that has pipes that switch between metals within a rail
this, but ONLY aluminum. no concrete, just aluminum.
@@ncnnjnicksb2 HEATED aluminum so it makes your wax just drip off.

In metallurgy it's called 'galling', I see it happen a lot with stainless steel.

Because of chemistry? I think he means physics 😂
Thank you
It’s both, Y’know.

I have that same STORROR shirt lol
Me with tensor maglight trucks: I like your funny words haha
yup same here hahaha. why i love them, they take on anything
Damn, that first dude knows what the real pain is...

that first bail clip was CRAZY
This is nice for preventing tricks at unwanted places.
Every business in every metropolitan be changing their handrails after seeing this
I work in fire protection/sprinklers. I have access to pipe all the time. I have my own rail made with 2 inch pipe
“Aluminum skate parks grand opening 3 dead 122 injured, what went wrong?”
Governments: Hey boys, I have an idea.
John’s content is great for anyone randomly coming across this.
Aluminum can gall to other aluminum, basically tries to cold weld when you rub them together
That first video hurt
Is it weird that I just had a dream about John Hill
"We do a little trolling"
-Park owners after switching the skatepark metals to aluminum
Danm that fall made me feel it
Mr titanium trucks be ballin
Bmx riders love aluminum as well our issue is that it dents easy so if your trying to sesh a rail you get like 3-4 grinds b4 you have a dent in the rail somewhere that is going to bounce you off it
Brought the pain of seeing Zion bail like that back into my heart..
I use the tensor mag lights new all terrain geometry they will grind anything
As an addition to my statement I also run an almost impact support 8-ply so my board is only slightly lighter than a normal deck
I don’t even know what you just did but that is the coolest thing I’ve ever seen
This content is so good wth
Bro really had to show off his sick pipe knowledge
Builders “Write that down!”
Schedule 40 is a grade for pipe thickness. Most coping is made of pipe either a53 or a106 grade steel. Typically using a 1-3/4” pipe that is sch 40. Flat rails are typically a 44w steel. For anyone wondering that’s what to ask for.
There's chemistry in skateboarding 💀
New York: holy shit let's make all edges and ledge's that metal.
Those ASICS thooo!!!
In the first clip, the guy hitting the concrete made the ground shake bro that gotta hurt
Bro combining chemistry & science with skateboarding is next level genius 😎💯🛹🤙🏼
I worked at a fence company for awhile, used a bunch of scrap pieces to build rails.. schedule 40 is legit lol, grinds so well. For those who wanna build their own rails, schedule 20 is a little cheaper and works just as well!
The one with the ledge is my local state parks

That was one of the most stylish kickflip smith's I've ever seen at 33...
Bro has the Sweet drip from GTA:SA
Nice that you added some chemistry/physics to your video.
That’s more physics then chemistry
There was a brand of steel trucks that made a point of using steel vs aluminum. They where heavy and kinda expensive. I forget what they where called it was so long ago.
Bro wants us to suffer 💀
Paint your trucks on the contact surfaces with some touch up paint for aluminum window and Door frames, boom slick asf Boi
Why is the video quality so goood
Try beer can coping
I FUCKING LOVE SCHEDULE 49 GALVANIZED STEEL PIPE
It's schedule 40 non-galvanised steel
@@fliegendeschuhe5614 I will never emotionally recover from this.
Those Asics are sick👍🏻
Bro's educated
So your telling me my 13 year old ass spent 150 bucks making a ledge out of ALUMINUM AND IT WONT EVEN SLIDE😫
Those Asics are sick though!
As a guy who has a science comm degree i appreciate it that you gave a little science lesson while also looking fucking sick
as a welder I approve
Not even a skater and this is really fascinating. Good stuff
aluminum obstacles still obey wax, its all about the amount of wax
Bro did this video outside my old middle school 😂
This is an actual body positivity! 👏
?
Yeah I made the mistake of buying an aluminum angle iron once.
I hear my ribs crying thinking about aluminum stairs rails.
How the asics skate?
I didn't know Petr Sripol skated. RADICAL MAN
Pipe schedules are specific to the nominal pipe size. “Schedule 40 pipe” doesn’t mean anything.
So basically, if I am a local government who wants to screw with skateboarders, coating every surface I can think of in aluminum is a deterrent that wouldn't be noticed by most people.
aluminium coating is just going to scrape away, the whole profile needs to be aluminum
Look at this guy knowing his kinetic and static friction coefficients :-)
But it’s always gonna be Joa>John
I don't think that this is technically chemistry but probably physics
Trucks are made steel brother, keep up up the amazing content.
The hanger is made of aluminum most of the time
The axle and kingpin, yes, but not the meat of the hanger.

Skateboards are terrifying and I hate them.
Kinda surprised there haven’t been trucks developed with plastic/ceramic grind strips. BMX pegs have plastic sleeves now for easier grinds
Im pretty sure ive seen that a while back. I thought about it when I tried rails on my board and remembered my first boards tensors
imagine someone making a whole skatepark with aluminum
That’s physics dawg😭
how so? i understand forward motion friction and what not but wouldn't it actually be the base of the mineral compound first then in turn it dictates the physics?
@@theboochiestore ye I agree. It’s a mix of both i guess but mostly chemistry. Chemistry is what makes the physics come into play
@@CV-du5nb word that makes more sense i didn't think of the mechanical side of it
Never heard someone call steel pipe schedule 40 but I mean I guess its correct maybe
Different kinds of aluminum. Ideally you'd want your ledge to be a a harder aluminum than your trucks. If the ledge is softer (or similar) then you stick.
This seems like useful information fr
I didn't know any of this. I only knew I preferred not to grind aluminum... Cool!
I work at a steel fabrication shop and just hearing schedule 40 pipe is kinda funny, schedule 80 is the thickest to my knowledge.
This is the first time I've ever heard someone talk about pipe sizes outside of my HVAC/Refrigeration job.
“Im juice” 🧃
I tried skating again at 36 and busted my ankle and have a tendon popping out of my knee 😂
Damn did you even get the skateboard moving though?
Now I don’t know much about skateboarding but using aluminum for for grinding doesn’t sound like the greatest idea. Aluminum is pretty soft and I’ve seen it get worn down by much less.
Well. Not chemistry, but physics
Thanks captin
Not chemistry I think but physics. But so go on skater boy you have my attention still 💜
ASICS makes skate shoes now? 😮
It's called galling, and it happens with similar softness metals
That’s why my trucks are made of titanium
Good old cold welding
I use axle greese at the landings to make them cry
I’m not a skateboarder so I’m not sure if this is a dumb question lol but wouldn’t wax solve the issue for aluminum on aluminum?
Wearing the Walter White fit for that chemistry part I see
What about steel grinding on aluminum
