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!

That's really clever. No stress marks at the bend point. Nice work!

guys thank you so much for this idea!!!! youve saved me so much work, money, and time of trail and error. thank you

Nothing like multiple accidental car alarms to convey that extra feeling of professionalism.

XD that car alarm scared the shit out if me

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.

That fuckin' car alarm nearly gave me a heart attack!. Still a good bend though :-)

If you ever lose your job as a plexi bender, you've got the right skillset for a mcdonalds manager. "Flip it!"

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

The wife said her hairdryer was not "unused" - well, I haven't seen her use it since I removed the element, I'm proven right YET AGAIN!

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.

Good idea! And tx for sharing it with us! I'll make one as I want to make a big aquarium with clear edges!

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!
