Cheap Foam Wing Cutter




What do you think about this video?

andpet55: The nichrome wire is 18 gauge

archiguitarchi: Dumb question: Where can I buy NiChrome wire?

Soonmush: Thank you from your advice! I got now my own hotwire cutter, similar like yours <3

archiguitarchi: What gauge (or resistance) wire did you use at 12VAC please? THANKS again.

startazz: I used the same sort of thing to power my RC battery charger but i used the 12v rail and it worked really well,that was a good few years back but now i've got a proper PSU for all my battery charges. 

Joe Mountford: I made a hot wire cutter using these instructions and a similar psu, I made it with two outlets 5v and 12v it works perfectly and just what I needed for cutting my own wings etc, thank you very much, Joe

andpet55: On one long wire run I actually put two sets of clips on the wire. It worked really well. The biggest problem I run into as I do these is that the wire heats too hot at first and then cools as I cut. To cure this I start to cut as soon as I put on the clips and then let it go at its own pace. I slow if it needs it around the corners and just pull harder through the longer sections. If you need to reduce the voltage you can put a variable resistor (light dimmer switch) and play with output.

traveller0: Thanks !!!!!!!!!!!!

andpet55: Be sure that when you connect the wires that the "cutting wire" is between the two active wires from the power supply. Connecting the yellow wire directly to the black wire acts as a direct short and will blow your fuse in the power supply. The nichrome wire acts as a resistor and this is why it heats and cuts the foam. There is, however, a point at which you can have too much of the cutting wire and it will no longer provide enough heat to cut.

nilshv: Excelent tutorial. Tried this with my kanthal wire and it worked, but only when the wires from the psu was close to eachother (maybe 20 cm). Tried to add two more cables but it didnt have any effect. How do you do it? Do you have both the + cables together and both - cables together on each side?? Can you please make a video telling how you do it?

mlggeek1: Hey I need help I made the same set up but for me when I did it the fan spun up and then when I cinected vBulletin the wire to my wire is sparked then the dan spun down

PERIKYLLO ELGRYLLO: por favor podrías decirme que colores son los que puenteas para hacer funcionar el ventilador ?? gracias. buen aporte, muy gráfico

andpet55: En el centro hay un hilo de color verde claro. Lo cruzar con cualquiera de los cables negros. Gracias por su pregunta.

anthony16r: Even the minimum output current of 3A would generate a power of 36Watts wich would be largely enough, though the nichrome wire of my bow doesn't heat enough to cut foam just a little...Do you have any idea where the problem might come from? Thank you for your time, greetings from France ;)

Shroom Duke: Very interesting stuff! Where did you get your NiCrome wire? I was thinking of harvesting some from an old heater and straightening it out...

elmonova: Awesome idea. Unfortunately my power supply is to new, it seams to have a short safety shutoff...As soon as I make a short with the wire cutter the voltage drops from 11.5V+ to 0V When I throw the power off and back one, power comes back. Guess I have to look for an older PC. ...Or build one out of a transformer and a dimmer.

andpet55: When using this cutter, connect the green to the black wire before you hook up your clips to the cutting wire. You need to begin cutting right after which will prevent the wire from overheating and melting. This cutter will work on wings up to about 4 feet long. Thanks,

andpet55: I purchased Ni-chrome wire from the local hardware store used in hanging picture frames.

Nat dud: Thanks! Helped me a lot!

PERIKYLLO ELGRYLLO: por favor podrias decirme que colores son los que puenteas para hacer funcionar el ventilador ?? gracias

mlggeek1: Is it beacuse maybay the wire pulled to nany amps? ( I used a 26 guage stainless steel wire) plesesesesese help

Joe Mountford: I made one of these as per the instructions here and it works really great, I tested it on a new piece of foam and cut some wings cores and then realized I have started to build yet another model, oh well, but again great idea which works great, thank you 5*

andpet55: En el centro hay un hilo de color verde claro. Lo cruzar con cualquiera de los cables negros. Gracias por su pregunta.

PirateTravisJohnson1: Screw wings... FOR NOW. I'm gonna try to use this on EVA foam!

Patrik Chovanec: I have problem.. when i connect wire to the yellow and black cable my power supply stop working... ventilator stop rotating... can you help me? i followed your procedure but this is only problem

CCgirl2083: This is the best explanation on how to add a power source for a foam cutter I have found. Thank you so much for taking the time to put it up on here.

anthony16r: Hi, thanks a lot for your videos, this new serie is really nicely made, I actually couldn't find a suitable power supply for my bow for a long time now, The lenght of nichrome wire on this one is aproximately 3 feet and 30Watts would be largely enough to heat it at 600°F. I harvested the power supply from an old computer. It is rated to output a current between 3A and 12A at 12V(yellow wire).
