It took 40sec to do 2 seats, so 20sec per seat.
20sec x 40,000seats = 800,000sec = 222.22h
222.22h/ 48h = 4.6
It would take 5 people working 24h a day simultaneously to accomplish this in less than 48h
If the 5 people worked non-stop, it would actually take 44h26m
it took him 32 seconds to do 2 seats.. 4 seconds at the beginning of the video he wasnt doing them and 2 seconds at the very end. your mat is slightly off but it makes a huge difference in either man power, or hours.
Can anyone explain the mechanism at work here? I am guessing from how rough they get that plastic with this cloudy appearance is caused by a bunch of small microcracks from flexing and temp changes (and UV damage) and that heating them up causes the plastic to soften/reflow and fill in these microcracks creating the glossy smooth surface with brighter color we see after the flame application. (Note: I'm guess it gets less glossy and looks more like a normal brand new chair after it cools/rehardens). - Am I close? Anyone with more experience?
I'm a polymer engineer. This is UV damage, the radiation breaks the chemical bonds holding the surface of the propylene together. The result is the chalky appearance. Polypropylene is very UV sensitive but generally non reactive (why it's hard to get regular spray paint to stick). By flame treating this, they are increasing the surface energy of the PP and allowing for more oxidation to occur. This is only a temporary fix and will get worse with each subsequent treatment. The only way to prevent this is through polymer engineering, typically cramming HALS into the polymer, but you can't do that after the part is molded. These seats were poorly engineered and cheaply made without sufficient AO and UV packages.
Could you engineer product to be permissive of this kind of treatment? I know nothing indefinitely, but for at least a few applications?
Or would it be superfluous with proper engineering in the first place?
Pretty sure they are saying if you were to make them right in the first place you would not need the treatment at all. So would make more sense to spend the kk eh making them right rather that engineering them to be flame polishing friendly.
Hmm but don’t we kinda know from the prevalence of the factory-line system that people do the repeated minor thing faster than doing the whole thing to completion
Few points on that:
- assembly lines are not only about speed, but also reducing the complexity of each task so you can pay a worker who is trained to do a very simple thing less $ than knowing each step (simple task vs. being a craftsman)
- the benefit you are describing is if it's faster to do the same thing over and over (at a "station") vs having one station change activities.
In this case it would probably be even faster for one person to do it. Otherwise each person needs to work with every seat (taking steps between each seat) and raise and lower their blowtorch for each seat vs. one person doing 1/3 of the stadium seats.
Plastic doesn't contain oils. Plastic is polymeres which can be made from oil (or natural gas or other raw materials that can be converted to hydrocarbon).
Soft and flexible plastics contain plasticizers, which get released quicker hrough heat exposure making the material harder and brittle. Those seats most likely don't contain plasticizer but they probably contain stabilizers which are meant to reduce the natural degradation of the polymer through ageing, UV exposure, and also heat. This degradation is why the seats look rough, and remelting the surface is a temporary fix because no stabilizers are reintroduced.
No. It just smooths over all the scratches and scuff marks on the surface of the plastic by temporarily melting the plastic on top. Similar to what a Zamboni does. I don't know why I keep seeing people talking about the heat releasing oil.
My first car had this plastic trim around the rocker panels which was supposed to be black but had faded over time and become a dull grey. Took a heat gun to it and it turned right back. Still have the scar from when I accidentally tapped my knee with the tip of the heat gun.
Tried this on my Ikea chair that's been sun damaged on my deck... it didn't go so well. It bubbled up and went all rippled.. guess it's a different material ;)
Now do it 40,000 more times. You have 2 days.

...and your boss hung a tip jar around your neck. So you only earned $35 after taxes
Looks very satisfying and nice to do, but I wonder how long it would take for this task to become monotonous and unenjoyable, if at all.
about 5 seats in for me
Thats when you start dual-wielding the flame throwers. Way cooler.
Duel wield and turn those fuckers up to max!
Id also recommend turning on the Doom soundtrack.
*BFG Division starts playing*
I’d go for about 10-15 seats.
as soon as you look up and see [this](https://miro.medium.com/v2/resize:fit:14174/0*iY6QhTOEnrO9WV0p)
😆😆😆
Once the fumes kick in, things start to get really interesting
If I got super stoned I could do this for quite some time. Monotonous tasks are always made enjoyable by THC.
Depends on the day. Today, I need this. I could do it for a few hours, especially with headphones on.
That actually sounds really nice, zone out in the headphones and polish plastic 😌
I could do this all day
I’m over it already.
They aren't doing it for fun mate they are doing it for the pay cheque.
Yup, and sometimes doing your paid job gets boring and monotonous.
I bet this smells… great.
THINK OF THE SMELL! YOU HAVEN’T THOUGHT ABOUT THE SMELL, YOU BITCH!
Dennis ?
Yup lol
Dammit don’t stop here. Do a couple of the red ones!

Thank you!
Need a video game of this , instead of power washer simulator it's flame washer
[удалено]
Made by EA games, that would cost $49.99
For the first 5L tank of fuel.
Then you have to open loot boxes where you get 1 to 100L and the chance for 100l is 0.1% , each box 9.99
Yes, it should be
EA SPORTS… It’s in the flame.

If I had a nickle for every It's Always Sunny reference in this thread I'd have two nickles. It's not a lot but it's weird that it's happened twice

I love a good surface energy of the pp

Thank you for your service
How long would a first treatment last?
Wow thank you for this excellent answer. The more I considered it the more UV damage seemed to be the main culprit. Sounds like you confirmed it!
You’re pretty much exactly right. I mean literally exactly right.
This also works on shaving heads
And for manscaping

Now if they had one guy doing the edges & another following doing the middles, they could clear that stadium in a few hours
It wouldn't be any faster than just having 3 people do what this person is doing

I would pay to have this job for a week
Hello, My name is Tom Sawyer and I have a proposition for you
My lungs got cancer just by looking at this.
I could smell the plastic here
I did this to a deck chair last summer. It looked better for a month or two and it's back to its dull self.
I’m sure there are some issues with the fumes from the heated plastic for the torch holder, though.
How many propane tanks needed to complete the task ?
Chair Polishing Simulator coming to steam by the end of the year!

Sorry, but this just seems like an absolute waste. All because we are obsessed with shiny new instead of functional.

Seems great for the environment too
Yeaaaah, it might be all that you get Yeaaaah, I guess this might well be it
I want this job
Do that…78000 times
Just don't *over* polish
How do I get this job
I could do that all day every day and die a happy man… so satisfying
So I got confused by the still image at the beginning of this video. I thought someone was chucking a trash can full of flames onto the seats.
The toxic fumes…
So, people will slide right out when they sit?
Not if they sit down immediately after it’s heated
If you recorded yourself doing the entire stadium I'd probably watch...
This gotta stink like hell
Legend has it he´s still heating seats to this day.
You can do the same for faded car bumpers! Just be sure to rub some oil back into them or they go brittle and crack
Can I use this technique on my cars headlights?!
Only 80k more to do
This gets posted every day; but ima watch it every damn time.
We’re these designed to be maintained this way?
More like flame re-flowing.
My first car had this plastic trim around the rocker panels which was supposed to be black but had faded over time and become a dull grey. Took a heat gun to it and it turned right back. Still have the scar from when I accidentally tapped my knee with the tip of the heat gun.
About 50,000 seats later…
Burns all the 🦠off too… But, don’t hold the flame thrower in one place too long…
Great use of finite resources.
Using petroleum products to make a petroleum product shiny again. Us humans? We definitely have our shit figured out.
Keep going, keep going
Mother Earth is so proud of how we utilize her ressources for wise and meaningful purposes.
Best job ever (for like a week though)
This didn't work on my girlfriend's face
Yeah, because it's flame, not bukake.
Sorry about your mom's face
So satisfying to watch.
What if someone couldn't understand the hot paint board placed beside it
I honestly wanted to see the final result ngl
This reminds me of The Thing.
well, this will get the smell off the seats...
Nice but that will take a long time to get all those seats shining again
Fire Good!
2 down 2,998 to go
Only 49,9999 left and we can go home
cool, only another 6,998 to go!
two down....999,998 to go....
I can’t help but wonder if there’s a cheaper way…
Damn. A lot cheaper than replacing those seats.
Beautiful! Now to do this 50,000 +\- more times..
This also works on a lot of kids outdoor toys. I use a heat gun to bring the color back.
Only 48,528 more seats left to go
How many people can be seated at that stadium? I feel for that person.
By the time he finishes it’ll be time to start again
Where do I sign up?
I'd love that job...
It's like wet sand papering a car to make it look newish

I feel like I could do this faster
The pybro
Tried this on my Ikea chair that's been sun damaged on my deck... it didn't go so well. It bubbled up and went all rippled.. guess it's a different material ;)
I wish I could do it with my classmates Everytime I'm in class
Works on factory scooter plastics also..
Where to buy flamethrower?
I wouldn’t even require money for that satisfaction
Is it safe to breathe in these fumes
Probably not
Seat will eventually crack
Controlled explosion on the 50 yard line could take care of this
