Thanks for posting this design. I made mine a bit larger, and found that a ball point pen did the job of the dull knife quite effectively. This creased the paper along the lines without requiring me to dull one of my knives and make sure I didn't press too hard.
Tip: be aware of the direction of the creases, score the paper to the side that the crease goes to, this means you will be flipping the paper over from one line to the next, and reversed on the other side of each corners, this will help the folding process go a lot faster and help keep the paper stronger too.

Many thanks. I signed up to the site. Got the plans in the end. Tried the paper section out. worked great. Thanks again for taking out time to reply. Regards.
Hello James! Thank you for the awesome video! I tried registering on your web site in order to download the plans, but the registration seems to be down. Also, receiving error messages when attempting to contact you via email form. Any chance you can help me obtain these plans? Thank you very much in advance
The easiest way to get a good seal is to unfold the bellow flat so you can roll and join the page end-to-end before refolding. It's trickier to fold this way, but it's not impossible.

I like using a glass cutter for creating the crease lines. It doesn't cut the paper

need double sided drawing for that?
You can recover them with tyvek type bellow material fairly cheaply, if you recover the old ones yourself. Regular paper won't last very long at all.
Why are the folds in alternating directions? Could the same functionality be achieved with uniform folds?
thanks from France it's cleaver tuto!!!
You're welcome!
Well done...!!!
Best wishes from Bavaria / Germany. :-)
with a little stronger material i am thinking how this can be used for making a low-cost patient ventilator ....
Thanks,
Best wishes for Wisconsin, USA.

Your bellows engine reminds me of the Brayton cycle Barber engine of 1792.. it would be great to see a working copy of that engine...

No worries. I don't get on every day either.
Cool
just get a large spring and put a plastic sheet round it.
Is there there a mathematical reason why it is in a hexagonal shape?
bogtheforest nope, at least not planned. It is basically a based what I seen on old time cameras.
JEPLANS Actually I just realized it's not in a hexagonal shape...
