How I Made my Ultimate Hotwire Foam Cutter - part 1 of 2
HTML-код
- Опубликовано: 8 сен 2024
- A hot wire foam cutter / styro slicer is a great addition to the workshop, useful for prototyping, mold making for concrete and modeling with foam.
I have created a feature rich and versatile hot wire foam cutter with a bunch of jigs to assist in creating exceptionally accurate hot wire cutting.
This hot wire foam cutter includes; an inbuilt LED light, adjustable angle arm, Volt and AMP meter display with adjustable volts up to 15 volts allowing the temperature to be precisely controlled. additional port for hand held accessories, circle and cone cutting jig, 45 and 90 degree with set stops jig, the never seen before quick change straight edge jig, thin rip fence jig, and fence, quick release tensioner, quick wire clamp release, micro adjuster for setting up the nichrome wire to 90 degrees accurately, foot pedal operated. and a bunch of other neat functional and design features.
The foam cutter / styro slicer has a high level of precision and with the innovative straight edge jig you can get very precise straight cuts even in odd shaped scraps of foam.
Building your own hot wire foam cutter / styro slicer is relatively easy , this is part 1 of a 2 part build video with a good overview of the steps to build the hotwire cutter.
I look forward to your comments , feedback and questions about my hotwire cutter.

Fantastic build. Really enjoying it and learning a lot. Looking forward to part 2.
Thanks for saying so! Trying to do a good job of explaining the rest of the build and the electrics in part two so it should be interesting :).
Another great video. The only thing I can think of to add would be a way to angle the wire the other way so longer pieces of foam could be cut on an angle like running a board through a table saw.
Clifton Snider there is a way to do this. The aluminium extrusion conducts electricity so using a drop in t-nut and small bolt I can add a wire mounting point at anywhere on the side of the top arm getting the inward angle, limited to about 45° though. But it I use the rear vertical extrusion I can get steeper angles.. As the whole arm tilts if I side mount I can still get the wire to be at 90° in the side to side direction.
Making that "slot/groove" ( don't know english word for it ) with drill press was new for me. Thanks a lot, haven't tought of that.
Great work, very professional design and finish.
Thanks! For the slot/groove i think i would get a better cleaner finish if i set up a similar jig on the router table and did it in small incremental passes.
Das ist die beste Maschine die hier vorgestellt wird ⭐⭐⭐⭐⭐👍eine hochwertige Arbeit gut durchdacht-Top 💯%🥇
Wir danken Ihnen für die freundlichen Worte. Ich freue mich, dass es Ihnen gefällt!
Thanks! I look forward to the next build video. Planning on building something similar for our makerspace.
This is Simply art
Thanks!
This is a great design Geoff :) Thanks ॐ
The Wood Yogi are you a Hindu
A few improvements i thought of, since the overview video.
1. Set the defaults, for example, there should be a way you can reset the tool to being perfectly perpendicular to the surface without having to reach for a set square and also a notch on top of the armature to indicate the optimal point for tensioning the nichrome.
2. Mark the rules and angles on the tool itself.
3. The circular Jig, make it out of transparent material (i.e. acrylic / plexiglass), in this way lining up and centering the foam should be much less of a hassle, just flip the whole jig up and look through it.
Regarding point 1. You will see in the next video (part 2) a metal bolt in the top of the plywood pivot support. I started to devise a system for some default stops but i found that the arm had a little flex in it and that the way i attached the wire above and below the base had a slight variance each time not giving me the repeatable accuracy. So i decided for the number of times i change the angle or the replace the wire, versus, the speed of setting it back to 90 degrees or any other angle, it just wasn't worth the additional effort. So i abandoned this part of the design.
Point 2. I tried to print on some vinyl to make some angles and dimension grid for the base and the pivot arm but the vinyl i had just wouldn't take the print and sizing was inaccurate. But you are right this would have been a great addition for sure!
Point 3. Yes absolutely clear perspex would have been great, i think by this time i was getting wary of cost on the whole build and was trying to use just what i had in the shop if possible.
I think you have great ideas and really thought through the improvements. Thanks for taking time to share these!!!!!
Great work !
Hello, my name is Adriana and I'm from Brazil, I loved your project, and I'm very anxious to see the second part of this project, thank you for sharing your knowledge
adeiana farias coming soon!
Thank you, I'm waiting
Hello Geoff! I came here from seeing you on our FB group. This is a nicely built little machine. I've also looked at some of your other videos, and I really like your whole channel! SUBBED!
Thanks Bernie! I am already subbed to you on RUclips and just followed on Instagram.
Thank you very much
Wow this is fantastic, well beyond my skills and equipment though :) think I may just have to buy one 😀
I so want to make it though
... /... Muy buen video. Muy buenas explicaciones.
Buen manejo de las herramientas.
Seguridad y Precisión....
¡¡¡ EXTRAORDINARIO !!!
Camilo Fernandez Pacios Muchas gracias por tus amables palabras. ¡estoy contento de que hayas disfrutado el video! Asegúrate de suscribirte.
This is a great project with a lot more features than I have seen anywhere else. Could you tell me what the overall cost to make one would be - you already had a lot of parts to use from your workshop, but if like me, and you had to buy everything, how much are we talking ?
I really liked the video so I've subscribed.
Pebbles The Cat I would be hazarding a wild guess but maybe £100 in materials.
This is certainly an interesting design you have for a hot wire foam cutter. I would like to know where to get the aluminium extrusions you used if it is available somewhere. Keep up the interesting designs. Well done
Tony Gasperini I got them from a company called Oznest. Thanks!
Great job on this foam cutter. Your videos documenting how you made it are top notch also. Can you confirm if the T slot aluminium extrude is 20x20mm?
Yep it is 20x20. Thanks for the comments;)
Hi, I like your video but unfortunately there is no links for the material u used. I dont understand at 1:33 what this laminate is.
It’s a laminate called Formica, you attach with contact adhesive.
Jeff I wrote to you asking , are you selling your machine and selling plans
smith smith no plans to create plans or sell my machine, but the videos series should help you make one.
Do you take commissions? This is some next level foam cutting
Salve, potresti dirmi il costo complessivo volendo ordinartene uno. Io non posseggo laboratorio ma sarei interessato al prodotto. Grazie.
Sorry not for sale
very nie
Great work, looking forward to the next part.
Nice rail track anvil. I need to get one of those.
Where did you get the aluminium extrusion from?
Andy Pugh thanks Andy! The aluminium was purchased from openbuildspartstore.com
Cheers Geoff; I'll check them out.
What Gauge nicrome wire? What is the voltage and current ?
28g
how much did you spend foe this project?
No clue
can you provide a link for the black clamps used on the fence?
Search bessy uni clamp
I had to turn down the intro, then I couldn't hear the speaker.............
Ok sorry
Will do better next time
Is this Ultimate Hotwire Foam Cutter you had built for sale? If so, how much is it?
Arch. Clifford Manuel Lu hello. It is currently a one off that I designed and built. I have no plans to put them into production. Although I have considered putting this prototype on eBay for sale.
So whats the title of this item on ebay and i hope the price is affordable.
How much is it with all accessories?
probably too much, as i have invested a lot of time in it :)
Arch. Clifford Manuel Lu hola q hi5 ero comprar un cutre donde hay
