good idea, I was thinking, there's got be an easier way to get the small plastic pieces 👍😎👍

Gracias hermano 👍🏼

kzfaq.info/get/bejne/oMyEbNOhl6jbeYU.html&pp=ygUWbWV0YWwgcHVsdmVyaXplciBzaHJlZA%3D%3D It'll do plastic, too. Build you own mini version in regular steel and it will crush your material into dust and chips easily, and cheaply, too.

No need if you use a shallow tray (metal or polythene). The plastic will dissolve from a sheet. Just leave it submerged overnight and give it a good mix in the morning. Just ensure it's covered over to prevent all the solvent evaporating. Worked for me.

I couldn't agree more! I am a South African State Pensioner. I have learned to make lots of stuff on KZfaq that has saved me a lot of money. A few weeks back I paid almost R400 for a tin of waterproof varnish. Since then I have seen two ideas on KZfaq that might have saved me that money! Since 1986 I have been making milktarts from a recipe I got from a book and have got over a lot of financial hurdles with just that one recipe. But first you need Imagination. Einstein himself said 'Imagination is more important than Knowledge' and he was right because once you have Imagined the thing the knowledge WILL come to you. Somehow.

Those are very humbling statements from both of you friends (GodisGoodAlways and Susan Collins) 😍🥰 I often say . . . there is a BIG difference between having knowledge or rather more like "awareness" (usually from school and education) versus the PRACTICAL things that YOUUUU CAN do RIGHT NOW or TODAY with that knowledge or "awareness". The **YOUUU** part is extremely critical becuz a degree in Nuclear physics (No matter how deep the knowledge) might Not result in YOUUUU being able to (or being ALLOWED to) do much with it in your SHORT remaining LIFETIME as a nuclear engineer with that knowledge, you are often STRICTLY CONSTRAINED to only PARTICIPATE in what the world of nuclear science HAS BEEN doing since 1950 🤨🙄. A degree in medicine also usually does Not result in ANY doctor coming up with a "cure" for cancer, diabetes, high blood or heart disease, Not even a cure for "flu" after 350 years of modern medicine 🙄. What we see shared in these videos however, is information and knowledge that CAN READILY and INCLUSIVELY CHANGE the RIGHT NOW situation (often challenging, desperate or even "hopeless" situation) of MANY people's lives (and INCLUSIVELY so) . . . from India to Peru, Romania to Chile, or even Haiti to Africa 🥰🥰😍😍.

What they said!!!!❤️❤️❤️❤️👏🏿👏🏿👏🏿👏🏿

Interesting! Have you got a weight ration of PLA to acetone? Also, can the acetone be increased to make it very thin? I'm looking for a preservative for a wood bridge and wood like something that with soak into the log beams to waterproof them so they last. (Store bought stains/preservatives have been garbage and not durable at all!) Thanks very much!

I thought that only worked with ABS?

​@@wingnutbert9685I would think so and I'm going to try it out on my buddy's utility trailer

Thanks! I like this idea a lot.. I'll give it a try in a well-ventilated space.

Liquid styro (gasoline as solvent , or acetone will do) is also called napalm...dip a stick in, light it, and it becomes a match that don't go out on a windy day or a storm 😁 Use with caution though.

And it's useful almost instantly too if you don't overdo the acetone (or mineral turps, which also works but to a lesser extent). Adding the acetone to the styrene foam helps here, or adding styrene to a small jar of your chosen thinner until it doesn't dissolve any more. I've used it in numerous applications but the most impressive was arguably replacing a nut and lock on a bicycle's crank.

Well I'm in my 70's and have known this since I was about 13!! 🤔😲😲🙄... Polystyrene foam in petrol or acetone makes polystyrene cement. Acetone has always been the goto adhesive solvent for perspex if the jointed edge is smoothed dead flat and the acetone painted onto the edge carefully as well as onto the surface to be joined, extremely strong and invisible joints can be made!👍👍👍 Surprised this is news to an old codger! 🤔

​@@pchykins6680 act accordingly

for smaller files i drill hole in to disposable razor handles and use them for handles

@@protonx80 Oh, I like that a lot!!

Can we use it in shoes soles separations

I mixed styrene foam and gasoline to patch nail holes in corrugated roofing iron. It worked very well.

​​@@protonx80great idea....I usually use golf balls

What kind of plastic was it?

@@nicolasparadis1407 acrylic - Plexiglas / Perspex are two brand names

The problem is that old shool stuff die along with the older people and not passed forward mostly because the new generations don't keep up with old good tricks till they are forgotten or even worse, lost.

@@nicolasparadis1407 As I said 'acrylic '

I'm tying to fix a broken corner on an acrylic sculpture I have from the 60s. It's clear acrylic and the chipped corner that needs to be remolded is about a cubic inch in size. As someone who has worked with repairing acrylic, do you have any tips?

I believe is plain acrylic. Let me know if you try it with polycarbonate. I'd be interested to know if it works. A quick search revealed that 646 is some form of thinner sold in East Europe/Russia composed of acetone - 7%, ethyl "cellosolve" (??) - 8%, ethyl alcohol - 10%, butyl acetate - 10%, butanol - 15%, toluene - 50%.

Speaking of 3D printing, I've done this for years with ABS filament to make goop for better bed adhesion. Same concept here. If you have lego bricks laying around, they are made of ABS as can be used for the purpose in the video. Just put them in a non-plastic container with the acetone, wait for them to dissolve, and you're good to go with multicolored goop (or liquid plastic).

Excelente observacion

Bonjour, il y a aussi le mélange colle cyanoacrylate (super glue) avec du bicarbonate de soude. L'essayer c'est l'adopter :)

bonjour, j'ai essayé avec du plastique cassant, çà fond pas. Quel plastique il faut ?

​@_jambonius_ it works but does not have strength for anything but a stationary, no stress application

et alors il n'y a pas d'âge pour bricoler , je fête mes 70 ans j'adore bricoler 😊

Ooooh good idea

Can’t see why not, if it doesn’t stick to the putty he used, it will probably not stick to the silicone mould…..

Tell me how it goes!

@@zaneaguilar5274 Sure! I've already got two big jars to make the aceonte mixture in. The idea is to make hard plastic embossing folders out of 3-D images I carved into a sheet of lino. I am experimenting with melting plastic but this method seems so much better. I may combine chemical and heat metling because I have to make the moulds with silane modified polymer. My experiment will eventually be most like the wonderful hard handle you made for the screwdriver. The glue was also amazing. II've got more than one jar because I want to try with all different types of plastic or acetate. Look I actually knew about this because I once tried to clean a sheet of acetate in a bath of acetone only to have it melt. almost completely That it would succeed so well as you showed I had no idea. So my own dumb luck.resulted in me looking for your film. I was flabergasted!

Just a couple hours depending on how much acetone is used. The plastic hardens due to the acetone evaporating. But, you can turn it back liquid by putting more acetone in.

You can just add chunks of styrofoam to a few ounces of acetone until you get the consistency you want and, yes, you can add acetone or styrofoam as you go to get it just right. I'm talking about styrofoam and acetone because it's the only kind of plastic I have experience dissolving this way. It's amazing how much disappears into the acetone, btw.

Acetone+styrofoam videos can be found online ... I'm amazed at using the hard plastic...

@@patrickcardon1643 If you have lego bricks laying around, you can use them to make multi-colored goop like he used in the video.

@@danwyan Good idea!

What do you use to make this strong glue ?

Creo que sirve el cloroformo.

I'm sure that the video shows acrylic (Plexiglass). Acetone will not dissolve polycarbonate (Lexan). However, acetone will dissolve acrylic slowly, methylene chloride will dissolve it faster, toluene will dissolve it even faster. But for the best results use chloroform. Also, chloroform makes the best adhesive for acrylic. With a little bit of practice (and a hypodermic syringe) you can make completely invisible welds in acrylic.

Polycarbonate?

won't work with plexiglass, that much i know

Realmente no es costoso ya que fue utilizado un plástico duro quebrado como darnos a entender que cualquier plástico duro desechable puede ser reutilizado.

Capitalism is lazy so probably

Cualquier plastico empleas, gracias. hé traido duro plastico, pero no se ha derretido

You could probably make something with water bottles or clear pastry packaging ,like moulded art work ,beads or relief work. You could probably add acrylic paint or acrylic nail polish.

Think there would be any downside to mixing chemicals? Like, dissolving a plastic bottle into acetone, with a spoonful of acrylic paint for color?

yes

i think you're talking about polypropylene plastic, they make shampoo bottles, bottle caps, cutting boards for kitchen, and many other stuff, from what i know that plastic doesn't melt with acetone. But i've seen people melting it in microwaves, and then pressing it into forms, there is a video with some guys wich made roof panels from this kind of plastic.

@@alexandrugajin763 I've also seen someone make boards with it like 2x4's and 1x8's (American sizes :( ).

Throw some in a jar and see if it melts?

They won't. If you get acetone or nail polish remover it comes in a HDPE bottle. Or #2 plastic

Bottlecaps are HDPE. They will melt in a sandwich press between two layers of baking paper. You can then put the melted plastic into a mould. Using glue on it or using it as a glue won't work.

Acrylic

@@majoduarte8722 Thank you. 🙂

So, maybe the nameless solvent is methylene chloride?

@@nessunodorme3888 No, he's using Acetone. He translated it in the video. Methylene chloride is nasty stuff. Overexposure to fumes can cause death. And it's said to be cancer causing as well. They do use it in production. But the conditions are controlled in the manufacturing process.

@@randomamerican471 Only one of his two solvents is acetone. I since found out the other one is a mixture of solvents described in another post here. Methylene chloride is not that dangerous unless you habitually huff it but there are probably other solvents you could try if you're nervous about using it. Maybe ethyl acetate? Xylene or Toluol?

@@nessunodorme3888 Right, the other was 646. It didn't dissolve the Acrylic. I'll use Acetone as it seems to work well. People using paint strippers containing Methylene Chloride in bathrooms have died. Not sure about the cancer element. I doubt it would be a problem for this if care were used. Acetone doesn't bother me. I wouldn't bathe in it, hehe. But it looks to work fine for this. I'm wondering if I could impregnate wood for knife scales with this stuff.

@@randomamerican471 I think there's an assumption any chlorinated solvent is potentially carcinogenic based on carbon tetrachloride's link and I keep seeing speculative warnings about chloroform, too, and now, like you about, dichloromethane. But I also saw the same warning about acetone somewhere today while looking this stuff up. I dunno where you live but in the US, anything to do with chemicals or chemistry is widely perceived as hazardous. If it doesn't cause cancer or make your kids grow antlers, then it's explosive or else you're making drugs! It's pretty easy to get spooked but, in the end, I agree with you: as long as you don't pass out with your nose in a tube of model glue for 45 minutes (like a friend of mine once did) or bathe in it, just use some care and you should be fine. Btw,i believe that DCM in a closed bathroom can kill you. I once had a close call when a half gallon of chloroform broke in a storage locker I was working in. But this post is long enough, sorry. One last thing: packing peanuts or the little beads that fill bean bag chairs are excellent sources of easy to dissolve in acetone polystyrene -- even at room temperature. What are knife scales?

пластик.

It doesn't work with plexiglass as some people say, that much I know.

The acetone evaporating is what hardens it. So you could add more if it became too hard/thick.

Only thing that sticks to silicone is silicone

styrofoam and acetone makes the plastic that model cars are made of. Polystyrene.

I had a friend who used it as poor man's napalm.

Styrofoam and acetone makes great caulking too

You're using the wrong kind of plastic.

Only certain plastics are dissolveable with solvents.

Make sure to get pure acetone though, no moisturizers or added fragrances.

Did it work?

Finally a real scientist.

@@juanparrajr Mostly it was plastics from store bought food containers , ice cream bucket, plant container , cookie container , bubble wrap , some foam , stuff like that , none melted after 5 days , the only plastic that melted was from a hoover vacuum cleaner that i scraped , the hose connector made of softer plastic and that turned to goo not liquid.

He used plexiglass not plastic. Plexi is an acrylic based material. Acetone will liquify it

@@eddievalenzuela3009 Yup im keeping an eye out for anything similar and thrown it in the jar.

Acetone

@@NosztraiAdam Thanks. What type of plastic? PVC, polycarbonate, Perspex etc?

@@ianmoore525 look acrylic sheet to me but I don't know. :)

Just watched again, you had already put acetone on the screen, sorry 🙃

646 is a MIX of solvents: acetone - 7%; ethylcellosolv - 8%; Ethyl alcohol - 10%; Butyl acetate - 10%; Butanol - 15%; Toluol - 50%.

To get it to cure without bubbles, you probably need to either put it into a pressure pot or a vacuum chamber and leave it for days until it's fully cured.

pretty sure its acrylic plexiglass not positive though

@@tconthepc_6958 thanks anyway
