I'm going to disagree with many other people and say the car alarm really made this video for me. I mean, the mechanism is clever and OP's technique is excellent, plus the opportunity to show grace under pressure.
Very helpful to see how to bend thick Plexiglass. I've been looking for this for a long time. Seeing the wide channel for the heating wire is very useful information. I've read that the gap should be three times the thickness of the Plexiglass, but never seen it in action before. Thanks.

Thanks fellas. I'll save money AND get to make those hi-tech looking enclosures. Maybe repurpose some old junk along the way. I have a bender brake for sheet metal--gotta love that harbor freight. BTW I like how you put the piece still warm and malleable into the final "application" so it would form to ideal fit--very nice technique. So actually you have taught us THREE things. 1) How to make a strip heater out of common materials (rather final product thereof) 2) How to bend plexiglass 3) Final forming as opposed to attempting to pre-form and risking botching it. You guys rock!

@@luminousfractal420 BTW this comment is 7 years old that you're responding to. I can't comment on the current version/revision of a tool. A bending brake is pretty simple though. There's the "bender" part you lay your stock on top of, and the "former" weight (or piece). I'd think it's hard to mess that up, unless they made it out of flimsy aluminum. --Or were you bemoaning the costs to ship it out to you?
I'd rather they did a video on how to install, test, and disable the car alarm. A LOT of planning went into the making of this video-at least 5 minutes worth-enough to get the camera turned on.
***** Car alarms are fairly complex beasts altogether... first you have to find the wavelength or frequency that the radio operates on, then you have to encode and decode the signal required for communication with the alarm. This all could take weeks depending on the intelligence, database and raw processing power of the data integrity team and their hardware. Unfortunately, the heavy-breather behind the camera, and the flipit man may not have the assets required to perform such an intricate and overreaching behemoth of a task. Likely they would resort to either: refilming a 5 minute video (beyond the scope of the intended budget), removing the battery from the vehicle (legal nightmare with attorney paperwork/legislation, not to mention the engineers that would have to be hired on to a contract of unspecified timing), or filming at a different location (possible zoning restrictions and hostility from local governing bodies). Sadly I believe the end result is that the videographic tribulation of blood sweat and hair driers that is layed out before us may be the only recorded documentation that can be produced at the current time. Hopefully future generations will be able to abstract any underlieing truths and key theories from this experiment and reproduce it in a future analogous digitization, documenting the relativity of localizing a thermal concentration and warping the bendy thingy with one's hands. Godspeed.
I just lay out a line with a square and draw it with a black sharpie. then wave a heat gun up & down the line till it's bendable & bend it to the appropriate angle, being careful not to stop the gun anytime or the plexiglass will bubble & froth. It doesn't do well on sharp corners, unless you have a form to clamp it in, but then, I have to have someone else helping me, cause it looses its heat to quickly. I enjoyed your video. It gives me ideas. thanks
Hi OTS, I really wish I was able to do this, but it's hard for me to picture how you set up the coil....would you mind explaining like where you got the coil or how you hooked it up? Great video, thanks!!! - LK
When I was at school (like 40 years ago) we had a commercial version of this in the Art and Craft section. They do a much better job of localising the heat than a hot-air gun does and give a tighter bend. Bedding the element into a bead of fire-cement would be one way to make it marginally safer. But I am guessing this is in the US where the mains voltage barely stings anyway.
I don't want to know what happens if you touch it. The one I had at work (A heater that accepted 1,2 meter wide parts) was low voltage. Burned myself a couple of times when a piece nearly either made contact with the wire or for some other reason, but considering the hot wire breaks the skin barrier that usually saves you from a very nasty shock, I don't want to know what happens when you accidentally make contact with it, 120 or 240 VAC or not. Just use low voltage or make sure you isolate the heater wire from mains supply. The last option is still dangerous should you make contact at two points on the wire, but at least you're isolated from ground. I certainly would not use aluminium foil surrounding such a wire but sturdy profile that you can ground should you NOT use an isolated solution.
It's not the voltage or the amperage like @philgray1023 said. It's wattage. That is determined by the resistance of the coil. You apply voltage to a coil, how much resistance it has determines how much amperage is needed to "push" through the coil. That's wattage. Volts X Amps = Watts. The only thing higher voltages do is allow for less amperage through the same resistance to achieve the wattage. Therefore keeping the electric bill lower and the size of the protection device and wire smaller in effective size. More volts = less amps to achieve the same wattage...
Good video. Just be aware of the potential electric shock hazard if you have mains voltage connected to that hair dryer heater element, and conductive aluminium film covering the MDF!
+Tom Nicholls You didn't read my comment properly before replying. I'll try again: The connection from the mains wire (bzzzzzt, shock, ouch) to the heater element is made above electrically conductive aluminium foil. So if this mains connection touches the foil then the foil becomes live... and then if you touch the foil you could become dead.
pretty awesome. Not sure i'd recommend having tin foil so close to the element. May as well put a knife in the toaster. Still an effective method of bending. Well done
So heat from electric wire allows plexy to bend? That is totally informative! Thanks! I will not be using my magnifying glass any more. So much quicker!
Would the plexi have been easier to put in your mold if you had left it across the heater element! Just curious as I saw what I perceived you struggled to get the fast cooling plexi into the mold. Just a thought.
if you point one of those laser temperature readers on the plexiglass, what temp should it be before you start to bend it ? Obviously a 1/16 thick will reach temp quicker than this expensive chunk you're demonstrating with.
Thank you for the informative video. My apologies for the negative comments made by others. No good deed goes unpunished. I would like to know what material you placed directly under the heat cool. Thanks!
I love your idea, i would even make another heater on the top (mobile, with weight) so you dont need to keep turning over bbq style. What do you think?
Pretty dang cool. Seemed like one of those days, didn't fit and the car going crazy .I was waiting for you to say " Bend it." Then that being followed by an almighty shatter and you saying, " SH**t."
Fascinating... Exposed live wire on surrounded by aluminium foil, covering the whole work surface you touch with your bare hand on each end of culture direction.
The heated coil was the key, but apart from saying it was from a hair dryer, there was no info on how much coil, or how to wire it up or how to stop the foil sheet becoming electrically live and deadly to touch.
could you use a curling iron? I didn't get how you put the hair dryer to the coil but on a small plexiglass window a curling iron might work it isn't very long but it only has to bend in the middle
What's the (barrier viewed @ 0:26) under the hair dryer coil made of and where did you get it? That's the key to using the hair dryer coil, the (barrier viewed @ 0:26) it's like the silver heat resistant board the coils are wrapped around in the hair dryer.
Interesting idea, but you've made the angle significantly weaker by bending back and forth in that way. You should have an even heat source and then mold it around a solid form. Only 'bending' it once.
It's no wonder how many people get divorced because the husband lost his bone and his funny bone! Wtf kind of reply to a funny comment. Don't call people stupid it's not very nice and it's no wonder how many people say stuff like that behind a keyboard because if they said it in person they would have a headache very quick. I'm sure your wife gets them a lot being married to you hahahaha. I'm laughing bwahahahaha. Dumbo
Dude if that coil comes in contact with the aluminum foil one of two things is gonna happen: 1) a big loud pop or 2) a dead hombre if someone happens to be touching the foil at the time.
You know I wanted to see just how long I could hold my thumb on a heating element before it got too hot. The electric shock was prodigious! I guess we all learn stuff at the age of 7 that keeps us alive later on.
Me too, I think when I was 5. I grabbed the element with whole hand then switched it on! Argh.... Shock ramped up quickly and was significant, but fortunate only about half of the 240V. I can still remember the pulses!
I wouldn't consider bending acrylic sheet with the improvised device shown here. Glass fabric-covered flexible heater elements are available that have no exposed conductors and don't glow red-hot, thus not requiring frequent flipping of the workpiece to prevent bubbling and scorching.
Right direction wrong tools guys. We did this 35 years ago. Try a coil from a clothes dryer. No need to flip, just wait for the distortion in the plexi
I'm going to disagree with many other people and say the car alarm really made this video for me. I mean, the mechanism is clever and OP's technique is excellent, plus the opportunity to show grace under pressure.
That's really clever. No stress marks at the bend point. Nice work!
