This never gets old. Bellows can be encorporate into so many projects.

Thank you, Sir Anthony Hopkins! I was looking for an instructional video on how to make the bellows that I have noted a while back, but you actually showed me much cleverer way of doing it!

Nicely explained. I'm looking to replace the bellows on an old folding camera so at least have something to go by. One thing though, at 05:11 you have to squeeze a bit of tape down the inside of the bellows to complete the seal. Why not have that piece of tape fixed, upside down, onto your board at 04:10, place one side on it and press it down, then the other and then add the outside piece?

Thanks for sharing this awesome project. Would be great if you could put up a link to download your template for this project. I don't know which program to use to draw that template.

Great idea, thanks for sharing!

I'm just looking to make the most basic bellows for my CNC to guard the rails against chips... and who shows up with the solution? Robert of course! It's probably the 10th time now I search for a solution on youtube and you pop up with some gold. Thanks again buddy.

Absolutely wonderful 👍

amazing! great tutorial!!

Thanks for this. I'm looking for options for camera bellows and, for non-tapering, this looks like a good one.

Nice! I will try it. Also couldn't help but notice the nice hacksaws in the background. I recently got a nice one after a lifetime of cheap hacksaws. Once of my true regrets in life is waiting so long to get my first good hacksaw. What a difference.

Hi, thanks for the great videoCould you please comment more on the type of tape you used in this project? I’m having issues to get one that is both flexible and not too thick to work with. Thanks 🙏

I've been wanting to build a manual air pump for my car tires. It's such a pain to get the compressor out, plus i think it's cooler to not use electricity, something i can use anywhere. I have a bike pump but that takes forever, i thought about making a bigger one, but then i thought about bellows, making some kind of accordion foot pump thing. Do you think bellows could get a tire up to 40 psi, i think that's around 3 atm?

Well done rob you did it cut your bellows down the middle to make a U section and you have your CNC machine slide protectors

Do you think bellows can be used as something like expandable conveyor belt?

Once you save the bellows drawing on the computer, you can use one of several programs to scale it to size (for the cross section of the bellows), and add length by putting more pages together. The sky is the limit once you have the base file established.

So useful!

Hello, I'm making some bellows for a wind powered instrument and I'm trying to use what I have to hand. I don't have the recommended tape - would papier mache work? If not, would parcel tape do the trick?

Simple and easy and photo useful. Thanks Rob! Oh, I just thought of something obvious. For the art of it, we could make different shaped bellows to. For instance, use a 30° angle instead of 45°, plus two more columns of slats and Tada! Hexagonal bellows. A Septoganal bellows might make a great prop for a fantasy costume concertina. (The music is beautiful, but sadly, beyond what humans can hear 😄)

Do you think you could sneak in some fiberoptic lights or LEDs into the bellows of an accordion? I've asked all over snd traditionalists say why bother. Engineers say they would've figured it out by now...

great job, difficult simplified!

Thanks for sharing.👍

Do you have any tips for a simple non-return 'valve'?

Way cool Robert

There are hobby CNC papercutting appliances out there that might do a good job on your bellows. Thank you for your very fine video. But I think the flexible vent tubing would be far easier to adapt and would make a very good bellows as well. It is available from 3" diameter up to over one foot (that would move a huge volume of air). "Tech Ingredients" recently published a YT video on a desiccant-based A/C system that really intrigued me. Its efficiency evidently far exceeded even the best Freon systems.

Great video. Why not put the template in a link to this video, for the geometrically challenged DIYers

beautiful video

Nice information thank you sir, what material is used for bellow

nice!

You have given me an interesting idea. An emergency flow battery! So I want to give it back to you because that's who you are! You are the impossible battery guy. Ok so a while ago, a Japanese inventor came up with a zinc or magnesium based foldable box battery that you would just add some water to and it would run. But what if you just wanted to use only a little bit of metal to reduce the footprint? And you still want that big amp output to start a car or something like that where it's a burst of energy that you need rather than a big continuous amount. For example for you want to charge a life saving device quickly. Or you are in the water after a plane crash and you want a big burst of light from a high power photo flash or a big LED... Okay, so you get two belly.... plural for bellows... And you join them to a high surface area cheap fuel cell in between. Next you add dry chemical crystals...a battery salt or ion source. You pack it like that as a product until you actually need it. Finally, the time comes! You need to charge your phone! And quick! Your boat is sinking and three hungry sharks are waiting for you! So you add some sea water, close the plug and you start swishing the bellows back and forth passing a large amount of reactants between the plates on each pass. So with a little bit of water and only a little bit of human work, you can extract a huge amount of current for as long as you got reactants and strength. It's basically a tiny high energy fuel cell which you can keep dry until you need it. Also you have lots of carbon materials to make this device printable and Amazon sellable to make lots of money to continue experimenting.

hey mate what do you say about patent licensing of a new battery technology .. Cheers and great video as usual

Method is everything!! Thanks so much for sharing your technique with us, it looks efficient and effective!! And... dare I say... "first?" 😋

Hello. What is this black adhesive film? Where can I buy it?

Great Knowledgeable video sir but as a physics lover i want to ask one question that in India a state name called Uttar Pradesh there's peoples lift their wife's skirt by using remote as used in tv so i just want to know what's the principles involved in remote based technology..... If you won't believe in this than pls listen song lehenga utha deb remote se with English subtitles....!!!!

When in doubt, gaffe tape!!!!

Rob needs a laser cutter..

You should of placed a link for the tape I googled fabric tape and could not find it.

Can you park a copy of your stencil some place get-able ?

Dry ice smoke ring ejector triggered by speaker coil?

Sir I need ur help in graphene synthesis

👍

Now, what about the rest of the accordion ❓🤔
