How to make hot knife cutter Acrylic, Plexiglass, Plastic, PVC and Foam Cutter

[@asrarhassan]

I didn't want to cut the bolt, so I wrapped aluminum foil around the blade and fastened it in the solder iron, it worked too. Brilliant Idea. Tested it on various plastic and acrylic materials, worked like a charm.

[@arunkamal2320]

Wow...Al.foil is still great idea.👍

[@trying2savenature891]

Great. Did you see any plastic melt sticking to the blade after cutting plastic a number of times, Forcing you to change the blade? This is important for me to know, I am doing a small test. Want to gather data from different sources. Kindly let me know. Thanks.

Just found this - I've been looking for a way to cut acrylic without having to make dozens of scores. This looks super easy and doable even for me! Thanks!!

[@Mrbobinge]

Exactly what I need. Brilliant ! I'm an old hand in the workshop making gadgets. Never seen this before. Simple concise demonstration. Thanks.

[@nrich5127]

Very good idea that will help me make a stencil cutter with an existing soldering iron. The way you were cutting was parallel to the jaws and the bolt was rocking as you cut. Just as a tip - when to lock your bolt in a vice and start cutting with a hack saw - cut in the direction that is 90 degrees from the surfaces of the jaws of the vice thus the bolt is always supported by the jaws and it will not move as you cut.

[@ZippedUpKitz]

Excellent tip!

@@trying2savenature891 That would be determined by the heat rating of the soldering gun and the type of plastic.

Brilliant ! A perfect example of how a resourceful mind operates, finds a way, and saves money for investment in more fun at the bench. My kind of guy, whoever you are. Bravo!

[@saadams4937]

Gave me an excellent idea... I'm going to bypass all the efforts at adapting the screw as a receptacle and use the blade holder from the tip of an Exacto knife instead. And the Exacto blade that goes with it, of course. As long as it gets hot - and it should - it should work. Thanks for the idea!!!

[@kevin7rxxx346]

Dang let us know if it worked

[@saadams4937]

@Kevin 7 Rxxx - Well, it kind of worked. I put the Exacto blade with the holder and the collet inside the tip of the soldering iron. I tightened the two little screws around the stem that I had inserted (the collet itself did not fit, but was needed to provide stability to the blade. It all heated up nicely and I tried it out on a plastic takeout tray. Worked fine until I got too deep (about 1.5") and then the edges of the plastic caught the blade and pulled it loose. Need to figure out a way to clamp the blade in firmly.

[@Mehmetyldrm_]

@@saadams4937 The problem with the Exacto blade holder is that it has 2 vertical cuts instead of 1. The screws can only provide pressure from the x axis, but not the z axis :)

[@saadams4937]

@@Mehmetyldrm_ Trouble noted. Solution...? :)

[@Mehmetyldrm_]

@@saadams4937 I am not sure. You can slide in some copper wire in the holes on the z axis maybe?

Thankyou so very much. Have built a caravan with all around dark tinted acrylic windows. Am about to convert it into a coffee kiosk and need to cut our side window for serving hatch. Was debating hot wire and multitool but this looks perfect.

[@molecularaudiocanada]

@@trying2savenature891 Thanks for asking. I experienceed minimal issues when making hot blade cuts with extruded acrylics between the thickness of 1/8 inch - 7/16 inch. I managed to get clean cuts with no plastic beading up or sticking when applied to 1/2 high impact lexan. My only advice is that consistency comes with pacing cuts with a steady hand.

[@gangsub68]

I think that iron made of glow plug (used in car) may be better in cutting plastic, pexi glass, pvc etc. Thanks for your innovative idea and presentation. A thumbs up!

[@GraciaBelievesthatJesusSaves]

I was looking for sumthing like this in the store ,maybe i overlooked it and its somewhere to be found ,but if i dont than this is a great idea 📝

[@mercuriallimit]

thanks to you that encouraged me to try it out!! I found that it cannot cut well if it's too thick (4mm for me) if you have to cut a long line. But if plunge it straight down it will make it to the bottom. Dragging it but not through it makes the reattached at the beginning again so kinda no use LOL Nevertheless thin pieces should work like charm.

I just did that with my wood burner lol… I needed a hot knife and it had different size collets to put different types of tips into the end for,wood burning… so, I just slipped one of the blades from my exact ò knife into it…. Shazam! I have an instant hot knife! Works perfectly!

Great idea. Keep in mind that some bolts have a protective coating that gives off toxic fumes when heated, so use precautions.

[@yippy7951]

And plastic also gives off toxic fumes when melted so it's best to use it in a ventilated area

Wonderful bro very nice idea 💡 👌

[@rgbtvuk]

Brilliant Thank you very much.

[@WarthogARJ]

Good idea. And you can make it better by using a thin piece of copper: no need to be sharp, it's not the edge that cuts, it's the HEAT. And in the same way, use a copper or perhaps brass rod instead of the bolt. Easier to cut too. Well, is a perfect task for a Dremel saw. And to make the cutting process more uniform/even, you could increase the thermal "mass" of the soldering iron: say by wrapping the end with copper wire. That will make it take longer to heat up, but then it will STAY hot as you start to cut thicker pieces. And you could wrap the end with high temperature insulation: can get a ceramic "wool" that won't be affected by the temperature. So the idea is to heat up the end, and KEEP it hot (with the insulation and copper wire-wrap), and use the copper "hot knife" to do the cutting for you. The extra weight from the copper wire wrap won't matter in its new role of being a hot-cutter: it's not like you are trying to do delicate stuff with a light(ish) weight soldering iron.

If you are too lazy, Use only solder itself. Make the tip of solder sharpest as possible with grinder. It works fine and last long. Even the sharp tip will be usefull to glue between the edges of acrylic. Btw, the idea is come from this video 🤙👍

Just use the provided tip flip it cut the slot no bolt needed, then you have two tips in one.

[@milleniumfalcon9677]

It appears that the key to success here is to choose soldering iron of right power for the job, or with voltage regulator: if it's too powerful, plastic will melt too much, but if it has insufficient power, then you'll have to put a lot of pressure.

[@topgrain]

I think that's what I'm looking for, but I wonder if it would work on ABS plastic, like the hard plastic part of a car dashboard. I need it to slice through with minimal melting of the material.
