If you need specific colours Lego blocks disolve well in acetone.

[@russelblackwell6041]

Thats a great tip thanks you so in reality if you had small moulds, you can recreate things like radio buttons etc. make custom interior mods.

That’s a great tip-but my stepson would 💩 if he saw all his legos melted down like that😂

Do you know what kind of plastic? Polypropylene different from polyethylene, etc. I have always struggled trying to fix broken plastic, this looks slick​. Also, is this nearly as strong as original? Did not know this was possible. @autophreaktrishield

[@rgolab3174]

I just use baking soda and super glue. Instant fix with no waiting for hours at end for acetone to do its thing with plastic.

[@marsantilli]

Hi Gaus. ABS plastic dissolved in acetone releases styrene which is carcinogenic. I recommend using two-component epoxy resin. It reconstructs the missing parts better and has no health risks

[@GausDIY]

Thank you so much ❤️❤️❤️

[@Peter-mw8dn]

I've used this technique and it works GREAT where 2 part epoxy does not work.

[@jayd3217]

Just a tip if you rub wax onto a part that doesn't need to be fixed but you want the same surface finish in your repair you can use hot glue in the undamaged area to take an impression of the surface and then use the hardened hot glue as one of your repair sides and you will get a near seamless repair. As far as using the ABS it's fine as long as your in a well ventilated area and using proper PPE. Plus you will get a better molecular bond using the same material and a matching color. Which is better then Epoxy.

[@GausDIY]

Yes, Thank you so much!

[@projectsdontstop8441]

My current favorite plastic glue is permatex plastic weld but I'll have to give this a try. Thanks!

[@JanPleva]

it's not for all the plastic (hence you can see as he does using plastic cup for) and in case you will combine different tipe of plastic, it won't bond too much well, but for those, what can be melted by acetone or somehow reacts with (PVC, ABS, polystyren) it's nice tip, actually.

[@dennislindqvist8443]

What would be interesting is a durability test. I once bought a two-component glue with a primer made for polyolefins, but it still didn't last very long. Reinforcing with sheet metal still works best for me.

[@Didier123456789]

It also works with PMMA ans SAN.

[@davidsteinfeld9123]

Questions about your idea here I like it lots why not weld it ? Will the asitone work on all plastics? Some plastics are meant to with stand harsh chemicals like that of asitone And about how long will it take for the slurry project to dry or cure completely? Love the idea 😀😀💡💡!!!!!!

[@captainotto]

This works equally well with PMMA/Acrylic/Perspex as it does with PC as shown. I have been doing this to make specialty mixes of PMMA weld. Be advised that with PMMA or PC you want to make your donor chips as small as possible. With softer plastics such as PC, you can use a cheese grater or with harder plastics such as PMMA you could use a metal file. Beware that with PMMA, crazing is possible with extruded sheet. Best results are found when welding cast PMMA.

[@maxinvictus]

Can you specify the types of plastic in terms of the grading code (1-7) that is stamped on which work? Also what is the percentage of acetone that you need? Will regular nail polish remover work?

[@captainotto]

@@maxinvictus Well that was interesting. I never checked until now but it's surprising that PMMA is actually #7. That's a shame too because it is actually fully recyclable with multiple cheap and safe pathways. You may find PMMA sold as Plexiglass in US/Canada, Perspex in Europe, or worldwide as Acrylic (as in Acrylic paints or Acrylic resin). As for w/w I usually just eyeball it but you can definitely be more scientific about it. Start around 1:1 and work your way up or down as needed. Dissolving takes time. Can take several days. Use a container safe for acetone such as glass or PP (#5). Nail polish remover should be fine so long as it does not contain any oils, fragrances, dyes, or other chemicals.

[@corydalus981]

A great idea for plastics that can dissolve in acetone, but YIKES! I have a very nice scar on the knuckle of my left index finger where the blade went down to the bone from doing what you are doing at 6:09.

[@skip7243]

Been there, same finger. Nearly cut it off, never the same! Always cut away from the fingers.

[@fvrrljr]

Facts: actually with practice it's an acquired skill, better blade control to cut towards you. i read this how they prove it to be true years ago. just be safe Bro's

[@DrZipZwan]

I also learned the hard way, to never use the utility knife to you, I mean if it miss , straight to your finger! Always cut from you direction. If you need absolutly to cut something, to your side direction, make sure to never hold the object like he did in the video! Hold it in a way, with keeping in mind that if it miss cut, if wont hurt your holding hand.

[@enricogura5527]

Dont worry, acetone can also fix that😁

[@johnmilner7603]

I use Permatex Plastic Welder. It’s black, hardens like a rock in 10 min and can be drilled, sanded and filed.

But you pay for it- bugger that.

[@gorilladisco9108]

It's $15 for 25 ml. That stuff is expensive.

[@fahey5719]

Thanks for your video, it shows resourcefulness. Disposable minds people won't like it; "right to repair guys" will love it. One caveat: it only applies to *some* plastics, those which can be dissolved in acetone themselves. Clearly syringe, adhesive tape and acetone bottle (I guess polycarbonate) do not. But it applies to *many* everyday items. You should add an extra adhesive bead on the outside of that battery case. Congratulations.

[@LoGiNaS16]

Cutting with knife with the sharp blade side into you - amazing idea!

[@julialafon]

😮 Muchas gracias por esos consejos pero una pregunta y el plástico donde se echa no se derrite 👍

[@russelblackwell6041]

Always face the cutting blade edge away from yourself

[@Turbo2Pete]

OMG....yes! I was waiting to see "in my next video we'll talk about how to bandage an amputated finger!"

[@Jim_One-wl4ke]

Yeah agreed, the fist safety practice that I saw in this video..please cut direction away from finger 😅. ❤thanks for your video.

[@renesolaire8319]

Opposite. It’s only possible to control blade progression when it’s closing to you. If it’s going away from you, you are weaker and have much less control on it so it’s very hazardous, and high risk of getting harm for you or others. But it’s true his left hand is not correctly positioned, and blade movement erratic, it’s probably due to video constraint.

[@kerry1979]

Can you use plastic bottles too? I do mold making & I bet too this would also work too instead of resin.

[@sypher0101]

The plastic used in the video is ABS plastic, which breaks down when you add Acetone to it, resulting in the plastic sludge. Plastic bottles are likely made of Polyethylene and Google says Acetone can break down Polyethylene, but I'm unsure if it will turn it into a useful sludge like in the video.

[@baltasariniesta8807]

La mezcla funcionaria?, si en lugar de acetona, se utilizara disolvente universal

[@gbm9115]

Nice idea 😊

[@tedlarson2078]

Brilliant

[@zebshirey3458]

To all those who are wondering why the plastic you chose isn't melting or if all plastics can be used Acetone will dissolve PVDF, polycarbonate, Polysulfone, Acrylic, PVC, CPVC. It will NOT dissolve FEP, PFA, ETFE, ECTFE, PCTFE, PEEK, Polypropylene If you use plastic that can dissolve in Acetone and apply it to any other plastic that dissolves in Acetone the residual acetone in your melted mixture will help to melt the edges of the plastic you're applying to and makes it very close to original strength. For other plastics, if you have a small area you need to repair, go grab some T Plus 2 Pipe Thread Sealant from the plumbers section of your hardware store. I know it says thread sealant but trust me, it will work for plastics fantastically. If you're trying to repair a large area, then look up how professionals repair plastic trim on vehicles and apply that technique to the large area you need to fix.

Bonjour, cela paraît vraiment intéressant, il faudra que j'essaye. - Mais l'usage de l'acétone (1:02), doit s'accompagner de nombreuses précautions et c'est de votre responsabilité de le signaler clairement. On voit bien vos gants, mais on ne sait pas si vous travaillez dans une pièce aérée par exemple, loin de toute flamme, etc. Par exemple vous pourriez écrire : "avant d'utiliser l'acétone, veuillez prendre connaissance des précautions d'emploi signalées par le fabricant."

Do you mean super glue (cyanoacrylate)? It's about $1 in my currency, while acetone is $5. But for those price, you get 25 ml of super glue, and 1 liter of acetone.

You might try MEK. Methyl Ethel Ketone. It may be hard to find nowadays if I remember correctly it will melt plexiglass. Sometimes it's necessary to cut towards yourself, just don't slip. And if you do get out the super glue

because it is a type of plastic that does not dissolve in acetone, acetone only mixes plastics containing Polyester

Evert Profesional in a trade that uses knives consistently will cut in both directions. Glaciers, contrustcion, mechanical, auto body etc. There are plenty of safe ways to cut in both directions. Cutting away from u is what you teach your children. In the real world u don't always have an option if u want a quality result. If u watch his video u can see when he cuts towards himself he stops at a point and flips it around. He knows when he gets to the end there will be built up energy and that's when ppl get cut he avoids this by stopping mid cut and changing direction to finish the cut now using the initial cut as a relief.
