    I have to cut some 4 inch thick 30h high density foam strips about 4 inch wide of a 2ft x 2ft squ section to glue onto the other square peices as the new ones are just a bit small so building this cutter will help in doing the job instead of buying one for a one of job. The foam cost me an arm and a leg as I'm doing my 2 x 2 seater sofa's as the foam cushions you sit on is way too soft as you sink into it.
    Many thanks for the idea

    Thanx for this cool DIY video! I have some quaestions. You want to use 100W power to cut. And you use serial connection with 3 resistor and an other resistor as a steel wire. Thats a voltage divider. Steel wire become 24V*(1,5 Ohm/6 Ohm) =24*(0,25)=6V. This Wire also have only 6V. This 6V with 4,1A current make cca. 25W to heat. Also the other 75W is to loose on the 3 sistors. Have i may a mistake, or thats is good theory with this 25W heating. (Sorry for my English. I only learned with datasheet readings.) I wait for answers.Thx

    • @philipbowman6415
      @philipbowman6415 5 ปีที่แล้ว +1

      That’s exactly right. The power supply does indeed provide around 100 watts of power, but most of that is warming the 3 resistors under the platform. However, it appears that 24 watts is enough to cut the styrofoam (power through wire I squared x R, 4 A squared=16 x 1,5 ohms=24 watts).

    • @jusmaag
      @jusmaag 5 ปีที่แล้ว

      @@philipbowman6415 Thx for your answer Philip Bowman . My project is immediately done. I prepared out a resistor wire out of a bad hair dryer with 5 Ohm resistant/m. I had hav'nt other used resistors too. It works fine, but the heat can be faster the resistor wire to burnout. Thank for your fine answer ;). And good day for you!

    Great Video and awesome setup! I only found one issue with this, and I am only trying to help you and others out. When you added the resisters it did not do anything but waste electricity. While you added more resistance to the circuit it was added in the wrong place. The point of the resistance is being in the wire it is what heats the wire up. If you add resistance in another section it will heat up that part aka the added resistors. So they serve no point in the build besides wasting power. Besides that great video!

  • @mikemidulster
    @mikemidulster 8 ปีที่แล้ว +1

    Great idea. I should point out that the actual power at the heating/cutting wire is about 24W, the rest being dissipated by the 3 resistors. Would it not be better to power this from the 5volt output of a cheap computer power supply? These can provide about 20 Amps @ 5v or even 30Amps at 3v

    @BillySugger1965 ปีที่แล้ว

    Superb woodworking. The electrical principles though… well…
    When I make one I’ll use this MDF plan, it’s superb. But I’ll constantan wire for higher resistance and a smaller, cheaper power supply. I won’t rely on a cold resistance measurement. Instead I’ll measure current and voltage when operating and calculate resistance. What you have there is something like a 12W wire cutter with a 40W heater underneath.

    • @SwallowForge

      There is an additional variable power supply video on the channel. You are quite right about the heat dump, and but the idea was to make it super simple requiring no electronics. Check out the power supply video using a simple pwm to give better temperature control using nichrome wire.

    I couldn't tell you the difference between ohms law and teslas. But I was wondering why did you pick 100 as your choice? I've always been fascinated with the way people make the indentations in my pistol boxes so smooth and the pistol sits in so perfectly. I've tried with razors and bandsaws but this looks like it would do exactly what I'm looking for. I could come in on the side and profile my weapons and glue the entrance and it'd be perfect. Thanks for sharing since you did all the electronic math, I wish I'd stayed in electronics class back in the 70s.

    Would this work with a power supply that outputs 4.75V and 0.55 Ampère, which would mean a resistance of 8.64 ohms. If i had the same cutting wire as yours then I would have to add a resistor of about 7 ohms. Would this work or did i forget something? Thank you in advance.

    Doesn't shunt simply heats the air with no use? The string dissolves only 25 Watts of power, and 75W of designed 100 are dissolved on shunts. Seems the same efficiency for foam cutting could be reached using some 8 volts transformer.

  • @THOMASTHESAILOR
    @THOMASTHESAILOR 7 ปีที่แล้ว

    Nice Job, You can buy a "Doorbell" transformer at Home Depot. I believe they come in different voltages, 16 or 24 volts.. You can run it with a regular, wall Dimmer switch, instead of using resistors.. That way, You can adjust the heat for thicker Foam.. If you're gonna use the blue foam, It's a little denser and needs a little more heat to cut too.
    I'm not criticizing, just adding suggestion for the viewers that don't have any parts on hand and have to build from scratch..

    • @SwallowForge
      @SwallowForge  8 ปีที่แล้ว

      +amaral sanchez it may be that the power supply you are using cannot provide enough current for the length of wire you have. A bigger transformer may help.
      If you can, measure the resistance across the wire. And use the power triangle to calculate how many amps you require. I found about 100watts gave enough heat to give a nice clean cut. But you may have to experiment.

    You could use kanthal A1 for wire. Its durable and I use it for vaping. I just finished my small foam cutter and used kanthal A1 0.35mm/27AWG 14,95ohm per meter. You might not need those resistors anymore. My foam cutter's total resistance is 1,85ohm and I used one of my batteries for vaping- sony 18650 Li-ion 3.7V 35A. It goes to 2.2~2.4A.

  • @Partysize2
    @Partysize2 8 ปีที่แล้ว +1

    Here are some useable specifications using nichrome wire and a 12 volt car battery. To get 36 watts of power, use exactly 18 inches of 26 gauge type 80 nichrome wire. If it isn't hot enough, shortening the wire to 15 inches will give you 43 watts. Shortening it to 12 inches will give you 54 watts. If you find 36 watts is too hot, lengthening the wire to 21 inches will give you 31 watts, a little down from the 36 watts.
    You might want to experiment with the length before you make the final size of the frame length spacing. If you have made the frame too big (meaning you need the wire to be shorter), just add 16 gauge copper wire to make up the difference. The copper won't heat up.
    Don't use anything but a car battery or a good motorcycle-size 12 volt battery with good connections, using 16 gauge or larger insulated copper conductors. If you have a 12 volt power supply which will put out at least 5 amps, you can use that instead of batteries. Attach the copper conductors to each end of your nichrome wire with a secure mechanical connection. You cannot solder copper to nichrome wire (the solder may melt even if you could).
    Using one of the above recipes will waste almost no power anywhere but in the nichrome wire. The highest current will be about 4 amps, for the lowest wattage about 2.6 amps. Not much for a car battery. Watch out and don't burn yourself. You are, after all, heating a wire hot enough to melt plastic pretty fast.
    You should know that I have never built a styrofoam cutter. I just know how to do the math for wattages etc., so I don't really know how many watts it takes. I assumed from the video that something around 35 watts works because according to the instructions there he was using about that much. The other 70 watts or so were just heating up the resistors.

    • @SwallowForge
      @SwallowForge  8 ปีที่แล้ว

      +Damian Appert Thanks for the great info, However there are certain aspects in practice that mean you need a little more power than in theory. The main one being power loss through heat dissipation. This can even be affected by the temperature of the room you are using it in, If your workshop is 10°C the cutter will need a higher wattage than if you are in a heated workshop as the wire looses heat quite rapidly. Too Hot and the polystyrene melts too much, too little and it won't cut cleanly. A simple way is to use a light dimmer on the transformer (or a basic Pulse width Modulator, although a dimmer is the easiest to source) that way you can adjust the power to the task you have in hand. all the best SF

    • @Partysize2
      @Partysize2 8 ปีที่แล้ว

      +Swallow Forge , good comment. I think I would suggest a variable 30 volt power supply with a capability of at least 3 amps if someone is willing to go for the extra expense. Another easier way might be to stay with one of the recipes I suggested with the 12 volt battery, then just add a little extra resistance wire length for cooler operation and then use a copper shorting clip wire to short out some of the resistance wire to get a higher wattage on what remains. The resistance wire then becomes a variable resistor as more or less of it is shorted out. To be clear, the shorted part would remain cool and the rest would get hotter, so attach one end of the shorting wire to the top and the other end just part-way down the resistance wire.
      This last suggestion may be a little more palatable to those on a tighter budget. I would caution folks to be careful not to accidentally short the entire resistance wire because this would produce some very dangerous heat and sparks. The shorting wire would melt in your hands!

    okay, what if you wanted to start in the middle of the foam and cut out a small hole, etc.? Disconnect wire?

    • @SwallowForge
      @SwallowForge  7 ปีที่แล้ว

      Instead of using a closed loop bolt for the top attachment, use a hook. Twist a loop in the top of the wire and place this over the hook. this way, if you need to cut in the middle, Switch off the power, unclip the wire, pass it through the foam (you may have to push a hole through with a skewer first) and then reconnect to the hook. turn the power back on and start cutting. Hope this helps. All the best SF

    If i use a 9v adapter or charger,is there any problem held?

    • @joe35lok
      @joe35lok 8 ปีที่แล้ว

      It's not only the voltage that matters, it's the Amps, the resistance (the length of the wire) and all components. You have to do the math using a multimeter and Ohm's law as stated in the video.

    Great video , BTW where can we find those resistors? Is there a type ? Because I dont have a spare PS. What is the wire temparature. Are we going to be electrocuted or burned if we touch it , or both :-).

    • @SwallowForge
      @SwallowForge  7 ปีที่แล้ว

      Hello Ogzasu, I only used resistors because thats what I had handy and so didn't have to pay for them. If you are going to spend a little money, I would get a Light Dimmer Switch instead. I would get one that can handle at least 400W. Wire this to the mains side of your transformer and you can regulate the temperature of the wire very easily. as Long as the output of the transformer is under 24 volts, there should be no danger of electric shock from the wire. Hope that helps. all the best SF

      I worked on a sign shop cutting styrofoam letters with a similar hot wire table. It was set up with a regular light dimmer switch like my mom had in her living room. This was connected to a 24 volt transformer you see in home central air conditioning systems.

    Don't use a guitar string, use a piece of constantan wire. You can get constantan in a 0,2mm thickness and 16,1 ohm per meter, ½ meter = 8,05 ohm and so on.
    with the constantan wire you can get the same result with ~25-50W

    Cool video!

    • @SwallowForge
      @SwallowForge  7 ปีที่แล้ว

      You dont need to build any of those things. You can use a hand saw and a drill and a screwdriver. I already have the tools so I use them as its quicker. if you dont have a soldering iron use connector blocks. There are always ways around any problem, just look around at what you have and find a way of doing it.

    I would have used a switching power supply this way you can regulate the voltage (which can be handy with thicker or thinner material cutting) awesome design tho!
