3 WORDS. GREETINGS, THANK YOU, 🙂
Thank you very much. I was easily able to extrapolate your info to my needs. Xellent
mejejejejeje
Interesting way to produce uniform thicknesses and with none of the waviness caused by cutting or by a moving wire. Great for small production cutting - the hot-wire version of a table saw. Well done.
Very good work! 👏 👍
I made one about six months ago which is 20" wide. Today I built a "mini cutter" which is 10" wide and I did finally break down and purchased a variable voltage power supply.
Well done! This video shows us all that's needed in a simple, straightforward & easily understood manner.
I used a scaled-up version of this tool when fabricating foam insulated doors for walk-in coolers and freezers many years ago. Cutting 3-inch foam at an angle on a table saw was messy and dangerous and the heated wire method saved the day.
I've wanted to build one of my own on several occasions, but never had a good idea of how to go about it. Many sincere thanks for showing me!
Just came across this channel this evening and I gotta say, Bravo! By far, the best tutorial on a diy foam cutter, simple and clear instructions. You can bet I will be making one for my crafting and costume making. Thank you for sharing!
Exactly what I was looking for. Great tutorial.
Smoke on the Water was fabulous! So was the invention!
How could anyone in their right mind give this FREE tutorial a thumbs down?? Cheery music music followed by some creative improv instrumentation, excellent camera work with the added drama of those still shots, and of course an excellent solution to a diy problem everyone will have to deal with at least once in their lifetime. What more could ya want? Thanks brother! Loved it!!
The music sucks and its too loud,I still thumbed it up though.
Good music. Good volume.
@@sirgalah4d20have you tried the volume control to adjust the sound levels!?
I did it, just cause u bitched bout it. But if I had to guess I'd say the music selection..😊 ( otherwise it was a clear and great video) but that elevators slide guitar gets old quick..but he made up for it with the Chinese guitar, then lost me again with the folk hoe down...😪
Thanks for a great easy to follow video clip with no waffle talking just plain visuals and as a bonus in kilograms for the rest of the civilized world like us here in Australia . Congratulations 110%
This was absolutely incredible. Exactly what i was looking for!!
Hi, do you have a link to a calculator for this sort of thing. I need the length to be 28cm and the Nichrome wire I have is 28g.
You made a great adjustable wire, foam cutter from inexpensive components, perfect for making thinner sheets easily. It is like a table saw on its side. Thanks, for presenting the building process and nichrome wire use information.
Great presentation video for the ambitious DIY'er that can afford the current transformer and doesn't require precise measurement in the cuts. However, for all the trouble it takes to make one, I think it makes much more sense to spend slightly over $100 for the exact same thing (with easier adjustments, graduated boards, etc.) from Amazon.
I remember using these almost 30 years ago for polystyrene foam cutting - worked at a special events company that had a lot of props, centerpieces, etc. that were made from polystyrene. This most definitely is THE best way for cutting materials like these with little muss or fuss.
But is it really about the tool or the ingenuity??
When I was a kid back in the mid 60s, I got a toy very much like this for Christmas. It was a bare wire about 6 inches long, strung upright with a base that made it look a lot like a band saw. It came with several sheets of foam with printed lines for various parts of a car, plane and house. I burnt the crap out of my fingers playing with that thing. Great fun back when part of the fun of toys was that they could be dangerous!
Üdv. Nekem is akkortålyt volt ilyen vågóm. 4.5 V elemmel működött.
GREECE- ATHENS ....Good morning my friend ..very important of your construction, with absolute clarity and examples of its use ... as very important is the table you cite..the whole construction is I would say magical for me ....
С удовольствием смотрю ваши сюжеты.
Всерьёз и по существу!
Спасибо. Успехов!
Thanks for mentioning the importance of exhausting those nasty fumes. Perhaps a video on building an efficient and safe exhaust fan would be a great help.
Just use a fan
Excellent! Love the detail, both in the video and the description.
Came for the foam. Stayed for the concert. (Awesome build, by the way.)
Great tutorial. The jig is nice and simple, yet does everything you need.
I'm definitely going to build one. With the ability to re-cut polystyrene form into clean useful shapes it has endless uses in hobby projects and even home renovation if you can get enough of the stuff.
If you want to glue together polystyrene foam then the easiest and cheapest is to use PVA glue (ie. wood glue, but it is also used in many crafting and "childrens glues" due to its non-toxicity, so you probably already have some at home). It's safe, cheap and cleans up with water (before hardening). Note that the white wood glue that dries clear is not waterproof, so for weather-resistant projects go with the (uglier) yellow variants which tolerate water much better.
Old idea very well executed with great results, nice to see someone using tools correctly.
Thanks!
Excellent . I can see great possibilities with this , especially if the table between the wire posts were adjustable up and down . That would eliminate having to reset the wire at different heights . Thanks for your time. 👍👍👍👍👍👍
Yes, adjusting the height of the table is also a great option, thanks for participating!
Love this invention, been looking to make similar and now realized i needed a charger. Great mate.
Not sure I will ever need to use this but you did a great job, it works great and was a great video to watch ,,,,,totally enjoyed the entire video!
P
Excellent video and I especially liked your answers to the rude and inappropriate comments made by the internet trolls.
5:55 was the best part. Thanks for taking us there, like only an old guy can.
I do not speak English
But the google translator serves
I found your channel a minute ago
And you truly have an EXCELLENT CHANNEL
I congratulate you from Colombia
Thank you, greetings from Moldova.
Quick tip- add a fishing swivel between the spring and a tensioning bolt. Nice and simple construction
Not that I would ever have any reason to make such an apparatus, but I must say your video had me intrigued to watch till the end.
Thanks!
I laughed out loud at the "Smoke on the water" bit! Good job!
You did a good job - especially the construct of the shades 4 the roundings ! To make the manufacturing more healthy : Put it to an open window, set a vent that takes the smoke to the opening. That will work….Go on with your videos
SMOKE ON THE WATER - you Rock!
Great foam cutter
As always nice and detailed explanation
Thank you & good job sir
Absolutely genius! Well done! Totally love the video and design!
I just built one following your video!
There are some slight changes since I didn't have all the tools but it works great.
Thanks for uploading this, it really helped me out.
Ah cool instructable. I already made a foam cutter once with guitar string wire. This guide inspired me to order real nichrome wire and change the design of the wire foam cutter I made. I could show you the result when it's ready :) I also made the 3-cell mendocino motor again because one of your other videos inspired me!
It's great! 👍 I'm glad my videos are inspiring.
Hey there, was trying this same project with guitar strings but they don't seem to heat up.
What do I do?
Ps. I also added a 12v filament bulb in series to know if it works. Hope that doesn't affect
Carsan Mario Odds are they’re too thick for the current you’re passing through them (the filament bulb will limit the current). You could try increasing the current (removing the light bulb and using an appropriate power supply), but you’ll need a lot of current for a guitar string. Try with 0.3mm nichrome or Kanthal wire (as in the video), which can be bought or extracted from heating coils.
Üdv. Volfram szál.
You can make nichrome wire of any length, but the longer the nichrome, the more VOLTAGE you need for the same temperature. And you need more tension (in kg) with a greater length of nichrome. I indicated the current and voltage for 30 centimeters from nichrome with a diameter of 0.3 mm.
For nichrome 0.3 mm long 30 cm voltage 8-10 volts, current 2-2.5 amperes, tension of nichrome 1.5-2 kg - 7:35
0.3 mm nichrome - aliexpress.com/item/1-10-0-3/32955677238.html

grain grain I love your vids I asked a teacher if I could watch them and she said yes
👌 Thank!
I think commercial cutter use
tungsten wires
You will find that the longer the nichrome, the more VOLTAGE is required to give you the same amount of current of 2 - 2.5 amps to achieve the same amount of heat.
Hi Looking to make a table that is 600mm of 0.3nichrome, what is the energy output? do you have an English link? I cant read Russian ;)
This was surprisingly entertaining; thank you
Dunno bout anyone else but for some reason, I REALLY love watching videos like this. Making your own tools
Same bug bit me
I did same project to slice Styrofoam for my hydroponics containers. I used 46 gauze nichrome instead 0.3mm wire with a supply of 100V AC. And I ve realized that 46 gauze were too thin for this project as it breaks very often. I could use a ticker version. Thanks for sharing.
Back again ... I couldn't pass up the opportunity to point out that the horizontal wire set-up in this video can easily be reconfigured as a yoke with a vertical wire to do scroll work. For that matter, it seems like we should be able to rig up a hand-held holder for the wire to do free-form carving ... the fusilage for a foam glider perhaps. The idea lends itself to lots of applications.
Anyway, thanks again. You definitely get a hearty like and subscription!
Yes, cutting a finished wing for a glider is a good idea and is used by glider model builders.
Excellent machine very powerful, congratulations my friend, one day I going to make one
Excellent .... Really handy for artists
The thumb-pushing technique is a easy way to get a deep burn acoross the pad of your thumb. A pusher stick and some vertical drag guides to hold the panel down will make for flatter cut surfaces. You want to make cuts pushing the stock against the "upstream" side of the wire.
The wire will be better retained if there was a smoother surface to slide across than the root of a machine screw's thread. A hollow brass rivet can be cut to make a smooth collar with a flange. Nyloc nuts hold their positions better than wire-supporting machine nuts and would help to maintain the set heights of the wire ends.
Bravissimo, un lavoro ottimo e con risultati eccellenti 👏👏
Get a fan kicking and you have a great set up. Nice work!
I did this on a bigger scale to cut foam for a barge I built. Used 120v house current reduced with a standard light dimmer switch. Learning curve. Start low and turn temp up. I started to hot and melted the wire in about two seconds but the dimmer worked really good. Cutting 48 inch foam.
Великолепно!!!!! Просто и полезно!! Удачи Вам!!
Great demonstration. I always put together a cutter in the same principle when I had to cut some styrofoam. But I made it so that I could move it freehanded like a handsaw.
Yes, there is such a design in the form of a stretched bow. For cutting the outline of the template this option is probably better. I know that model fans cut out the profile for the wings of the glider in this way.
.
Loved this hack and demo. GREAT work!
I LOVE this tutorial !! Thank you so much!!
Thumbs up just for the music that was great. Another thumbs up for video. 👍🏼👍🏼
Back in the mid 1960's my dad and I cut Polystyrene Foam Wings cores for model airplanes then we covered them with 1/16 balsa wood glued on using two part epoxy. We also covered some of the with poster board and contact cement, both both techniques worked great to make fast building and inexpensive wings.
Dope Video! Sending blessing your way, Keep inspiring!🎒🙌🏻
I muted the music and played my own. ;)
Thank you very much for doing this video, this is exactly what I was looking for.
Wow...what a beautiful job. Congrats
Love the Deep Purple on Nichrome wire!
I need to make a hot knife and this has helped me a lot. Thank you!
I liked that first song the best. Thank you for the informative vid. 😁
Nice build. A vere good video. And the music great . Thanks for sharing this one
Работал в цехе пенопласта оператором блок -формы 15лет,всю эту кухню знаю на зубок. Но снятие видео мне понравилось. Спасибо Вам за ваш труд. Лайк в поддержку канала.
Nice invention

Well done ,just for my dio project, thank for sharing.👍
Tremendous video. Thanks for posting.
Great video with easy instructions, well done mate.
Great video, not something I could find a use for but well done! Love the music.
Congratulations. Excellent job! Thank u
Brilliant. Entertaining, well done video. Good work.
Best cutter I've seen
ERES UN FENÓMENO, MUY BUENA IDEA.
Great Idea. Plus playing Smoke On The Water was an added plus. One of my all time favorites songs I still even have my LP from back then. It would make cutting very easy. Thanks
🤘
Info at 7:36 is exactly what i was looking for! Thanks!
Excelente video eres un genio, saludos desde México.
Single strand stainless leader line (used for muskie/pike fishing) works well too. Available at most tackle shops.
Perhaps, but I think for steel wire it will take more current to reach the same temperature as for nichrome.
О-о! Execution "smoke on the water" exceptionally exactly! Thank you! And a construction in itself impresses... It is good! even very!!!
I beg pardon - answered with a translator (badly I know English). I hope, it will be got it right...)))
Golden hands!..
Thank you!

Thanks for the inspiration! I made one and comes in very handy for slicing, however my musical skills suck.
Thanks great set up looks easy to use
*C'est tout simple et efficace!! Merci.*
Dude, this is awesome !
Dude thats freakin super rad. Definitely gets my thumbs up
Love this! Not sure if recommendations are acceptable however watching this I can see that building this for vertical (more intricate) cutting would be a great pt2
Just in case you're interested: ruclips.net/video/47cM1lvHEzI/видео.html
A table "jig" cutter. Mark the table where you want the wire to go vertical. Make a hole through the table at that point. Use an eyebolt positioned beneath the surface of the table as the fixed electrical connection and wire anchor. Add a vertical board to the edge of the table. At the top of the vertical board add a cross member. Use an eyebolt for the second wire support and the electrical terminal. Position the spring support on the underside of the vertical board. For straight cuts use a clamped edge guide.
Thats Great Achivement................Weldone Bro
Nice work. My experience with heat cutting of XPS is that pushing by hand has to be done at even speed, which is difficult to maintain on long pieces of material. Using weights to pull the wire through stationary material gave good results.
You think correctly!
Parabéns, muito bom.
Teria alguma solução para cortar espuma de pet em 45 graus?
Muito bom Parabéns nota 10 Obrigado
Greate job! Especially figure cutting. Thanks a lot!
Very informative and I loved the soundtrack. The music that is not the other sounds you emphasized. Maybe your next video you could instruct us as to how to run your fingernails down a chalkboard.
Excellent job. I'm not sure why I watched this, but good job.
Great vid, thanks a lot for sharing. Super useful!!!!
You had my 👍with the music. Good video
My dad made one of these in the 70's for making model airoplanes, I accidentley touched it and sliced my finger to the bone! Didn't even feel it. It was that quick.
Shoot..that's just showing off. Love it!
Excelente trabajo amigo, una pregunta,cómo se llama el aparato donde conectaste los cables? Se que es un regulador, pero tiene algunas especificaciones

Nice machine small & simple eficient and chip !!!! .
good idea. good work. thank you very much indeed.
All I needed to know! Thanks. Subscribed :0)
congratulations friend, I loved your video, especially at rock time....rsrsrs, congratulations people like me and you inventors who need to exist god bless you.
definitely trying this out, thanks, great idea, maddddttt
Genial!!! felicitaciones..!!!
This is exactly what I had in mind. I just need to get some nichrome and banjo music. Then it's go time
Just find a scrap hair dryer, heat gun, heater fan, bread toaster or alike.
Banjo 🪕😅🤣😂
Great video and very easy to understand. Do you think this would cut Closed cell high density foam, the kind that is often used in camera cases thanks
Does styrofoam damage the camera? I think not at all. Just the pores are closed when cutting with temperature. But the foam from this becomes hard on top, it is still better to stick fabric or leather on top, the more aesthetically pleasing it is.
