Homemade Styrofoam hot wire cutter 

Fastest tutorial I’ve encountered with no bs , RU-vid algorithms finally got it right. 🤗

I have seen several videos on how to build similar devices but what makes yours of interest is the use of PVC pipe and connectors and the deadman switch. Very nice. I love the design and would make mine smaller.

Fkn brilliant, mate. Bowing the PVC is genius. As the wire heats up is will contract (rather counter-intuitive, but physics). I found this as I'm putting in a couple of window A/C units that come with some insulation blocks; however, this is a really old house and as such, windows don't match the newer std. sized windows of newer homes. Forrunately, I never throw stuff in the bin and likely have all the parts and will reuse the styro packaging to make custom fitted parts to insulate around the A/C unit. Thanks for posting this.

I used a the adjustment from a bass drum pedal I was able to adjust the wire tension

Very clear and simple. Thank you!

you are a talented and brilliant creature!

That bicycle cable strand was Brilliant! Thanks! 👍😁 ......👣👣👣.

Good work.

Thanks for sharing this video & information. Great design and execution

simple, efficient, light... great!!

hola amigo muy bueno tu aporte, por favor indicar la medida y calibre del alambre nicrom para usar con la fuente que enseñas. saludos

If you used more current and went more slowly, do you think it would cut straighter lines?

Amazing. Thanks for posting.

Great video. I’m starting a project soon and I will need to cut some foam

Thank you!! You are brilliant.

As soon as you chucked the first piece of scrap I knew this video was for me! 🤣

Just watch your video love the idea. If possible can I please have the dimensions you used on the. Legs and back of your cutter and the size of bolts used thank you and greatly appreciated

Thanks bud, nice simple tot he point. Cheers

This is useful, cause you can find stuff anywhere even in rid off stuff in store room

Totally awesome! 🤙🙌🎯

parabens mestre.

Best wishes brother

Well made

Good job. 😆

Parabéns colega gostei muito de seus vídeos educativos ,

Looks like I have to make one of these soon thanks for the tips 👍

Can you add a link for where to buy the electronic components?

I think this is the fit to my dilemma though I am trying to split Foam creating two pieces from a single . I think this would be classified as "foam rubber" but am unsure. This is a great starting point for me

This is EXACTLY what I need to build to cut some viscoelastic PU foam. I will need about 22 inches of wire to cut my object that is 19 inches wide. Any suggestions on power adapter output and wire thickness? Thanks!!

Hi, but what kind of source for 90 centimeters?

What diameter (or Gage) is the steel wire you used? How about a volt-amp-x-section-length formula for those who want to use a different length wire?

32 awg?

what material and what are you cutting

Thank you

Cool channel! I got you Bro!!!✌🇺🇸✌

Nice build, Sturdy and waterproof. The only complaint would be that it's badly underpowered. Don't mean to sound like Tim Allen here but I've seen these types of cutters with proper power and holly crap, what a difference in cut time and quality. Very good build overall though,.. : ) great job,... *: )*

I enjoyed your video and made one just like it only with nichrome wire. I’m using a dc adapter that’s 12v and 2A, so close to yours. It’s just isn’t getting hot enough to cut. Not sure what I’m doing wrong.

excellent.

What Electrical instruments use this sir?

Oh wow awesome exactly what I need to build haha! Thanks a lot! I didn't think to use PVC pipe so far. I'd argue it would be better to use nickel wire instead of nichrome or kanthal. You want to reach a stable temperature, so the temperature coefficient of resistance is highest in nickel. That means the resistance will rise with temperature and lower the current going through the wire and thus stabilize the heat a little. Stainless steel 316L could work well too. The "ideal" would be using a vaping chip or a mod where the temperature is regulated by measuring the resistance of the wire while it gets hot. Also runs off of two 18650 batteries with up to 120 watt. If you really need a high performance "wire saber" :D

Hi! 32awg (0,2 mm) hot wire?

What kind of foam are you cutting in the video?

Can you please give me a rough sketch to cut a 70cm foam?

How about a 18 v at 2amp for a. 700 wire?

Faça para nois uma seladora de sacos plásticos

About time my search turned up the RIGHT way to do this project. Thank you!

Hello, you did a great job, i see you used a 12v output adapter, can it be made with a laptop adapter output 14v 1.79A Thanks.

do you think i can use 24v to heat the wire? I used a 12v transformer in my build and it just does not deliver enough power to cut through depron with the paper on it

Very inspiring...thank you. Im in real need of cutting ice cream bulk into smaller pieces for repacking. Done with knife... big problem with hard frozen ice cream... messy 😖 Hope hot wire would work better. What dya think?

No explicás mucho, ni das las medidas, pero me sirvió bastante tu video. 👍

Design ❤❤❤

Thank you.

I'm insulating my attic and will be cutting up 8foot by 4foot, 2inch thick expanded polystyrene sheets to fit in-between the rafters, can I omit the switch, and just leave the wire hot for as long as the power supply is switched on? Great video by the way, simple and uncomplicated.

Why doesn’t the pvc melt at the bolts?

can someone help me? i have an adapter that outputs 12v yet it so slow to cut styrofoam, is it normal? or my adapter is broken. its not as smooth as the cutter in the vid.

Cool

Finally one that appears to use an outlet instead of short circuiting a battery

Che filo usi per tagliare ?

I made this today I used PVC pipe 12ga power wire 12v 5a power adapter from amazon Crimp on connectors with heat shrink built in. 21 ga 0.7mm nichrome wire. Screw eyelets as shown in another video. No switch. I can get the wire warm but not hot enough to cut any faster than literally sawing with the wire. Any idea what I did wrong?

What’s the tool used in the beginning to cut the PVC? That things nifty

UK?

How much power will I need to heat up a .70 cm wire?

Right on! Question - if you made the wire distance shorter would you be able to cut faster due to more heat? Great vid man.

Hot wire kon sa h our adtopter

I built mine similarly. 22awg nichrome wire, 5 amp adapter and it worked for about 3 minutes, and now it won't work... Still reads like 12 volts is running through it. Just not sure what is going wrong...

Plz can some body tell me why when i do these short circuit occur and not like the video heat is generated (i followed the instructions)

Q tipo d alambre usa y numero

It works great but ... I want a unit that works more like a table saw, with precise edge alignment to make precision cuts. Yours looks like it would be better suited to sculpting freehand something artistic.

Que tipo de alambre es?

Adapter's output anyone ?

Ok buena

Hi friend

I used 12 volt 2amp adapter but after sometime my adapter damaged...is it my fault or the adapter? Plz reply sir 🙏🙏

Its a decent build don't get me wrong, and the effectiveness is unquestionable, but at 2:37 you know those are crimps right? They aren't meant to be soldered on but rather crushed around the conductor.

Cutting cheese with this tool must be a pleasure... 😜🇨🇭

Good job.sir I want to make 1meter long hot wire, I don’t know about this, Please give me few tipS I have adapter 220v~\50Hz/20w 12v and 1000mA Please tell me is it ok for this ?

👍😄

Let's be clear. It's for cutting EPS of expanded polystyrene only.. Styrofoam is extruded in a dye and makes mustard gas or phosphine gas, the other is polyurethane which is also toxic. EPS is not toxic when burning, it can affixiate as any burning material will, but not toxic, blue foam, yellow foam toxic when burning.

Have you (or someone) ever tried cut cheese or a cheese cake with it?

Should be a relay or transistor to switch the power to the wire, that switch will not last long.

Can you give me a list of the components needed

Where did you get the push button and power parts from, I’ve looked online and I can get them from Amazon but I’d prefer to go to an actual shop. Any ideas or suggestions. Thanks.

One nation under CCTV. Love the t-shirt

Would this cut PIR insulation boards?

You got to have 220v? Isn't there something 110v? Maybe a 2amp trickle charger, or a modeler's iron used to put cover on RC airplanes? I have one thats broke but it still heats up, and has the handle.

O problema todo é que ele entrou mudo e saiu calado

followed all the steps but it doesnt work.

Why doesnt mine work grrrr, tries several different power adapters with different V and A.... But nothing.....

ভাই এটা তৈরি করে দিতে পারবেন

life hack if you hold the lighter verticle you won't burn yourself

Could a wire, threaded through a frame like that ...be connected to the posts on a soldering gun and get similar results

Bhai work nahi kar raha hai

Does anyone know how to paint it so it becomes hard?

Those crimp lugs you soldered to the hot/neutral wires should have been crimped. Soldering instead of crimping makes the joint fragile and more likely to break because the wire can no longer flex where it meets the lug. Just a tip for next time!

I have had good success using an ‘e’ string for an electric guitar as the wire

I hope that quote on your shirt is a spoof because I sure don’t like the idea of BIG BROTHER looking over my shoulder 24/7 !
