Nice tutorial. I use to do it this way and it is a good way to get into foam cutting. My Vickers VC10 was built using the same feather cut system. I now use my own design CNC foam cutter which I've built many wings and fuselages on. 👍👍👍
Great video mate. I'm inspired to do 2 things now: 1. pull apart an old corflute (coroplast) wing and rebuild with foam, using my shiny new... 2. ...Arduino powered cutter (which I haven't yet built but am inspired to now)! Many thanks and cheers from Sydney, Aust - Dave
It was definitely a learning process, but SO worth it. We can now build and fly just about any design we want. We were doing lots of R&D until we fell in love with the latest design - the Manatee. It just flies so damn well!
Could you do a video of a manually fed cut vs using this pendulum fed? Would be interesting to see the difference, and if the PF is worth adding to the TWC. Thanks.
hello, Hello, Please can you indicate the dimensions of the wing (length, tip chord, chord, sweep) and the profile used . Thank you very much. Great job.
That’s a slick setup! I don’t know what wire you are using but you should look into René 41 wire. It’s what most of us use and it works so much better then nichrome. It doesn’t stretch as much when it heats up. I use 27ga. It more expensive but I only have to change it out about once a year.
Thanks! I will definitely check that out! Do you have a good supplier to recommend? The wire I have been using is certainly nothing special, I'd love an upgrade.
I am using a professioanal cnc wire foam cutter for my wings, and i would say, there is not very less work here)) Nice. By the way, what specific airfoil did you choose?
I bet an arduino and 4 stepper motors could bang these out with a lot less fuss That said, i really like the simplicity in this method youve developed.
IF YOU WERE TO STAND YOUR FOAM BLANK UP, ON EDGE, WITHE THE TRAILING EDGE DOWN TOWARD THE TABLE, AND LEADING EDGE UP, TOWARD THE CEILING), AND CUT MOSTLY IN THE VERTICAL "UP" DIRECTION", YOU MIGHT GET SUBSTANTIALLY CLEANER, FASTER CUTS, (BECAUSE THE WIRE WOULD BE CUTTING INT PREHEATED FOAM, (FOAM HEATED PRIOR TO THE PASSING OF THE WIRE,.. USING THE ADVANTAGE OF THE "RISING HEAT"...
Great video. Are you going to do a follow up to this one? Finalising the build? It's really hard to find a reasonably priced wing in Australia. I wouldn't mind heading down this route and start building my own.
That’s a good idea, we probably should do something like that. We learned everything we know about building wings from cats Firmcore, a small outfit that makes wings in Northern California. Why don’t you hit up David Foster with Team Hazard? I’m not sure if he is cutting these days but he may have some old blanks lying around he’ll send you.
Good question. The hot wire glides along the top of the airfoil template so gravity keeps it flush. The bow I use uses steel rods so they have some weight to them which helps. I am also sure to have the bow at a relaxed angle, maybe 45 or so degrees, so as it moves across the wing panel the wire stays flush. Around 16:00 shows the general way it moves over the airfoil. For the bottom I just turn over the entire wing panel and do it again. I hope that helps. If not let me know! Jeremy
I don't remember if you've moved on to CNC yet, but have you tried adding a foam board shim under the leading edge of the block to assist the initial wire entry instead of pencils? It looks like the pulley forces pull backwards and down, so tilting the leading edge up a little bit might help the wire get around that first curve without needing an assist. My CNC build is taking forever but I think I'm going to build one of these for Nick to mess around with.
Good idea! I’ll give that a try next time. I‘ll have to see how it impacts the trailing edge too. The bow can get pretty close to the table on that side.

I have seldom been so astonished by mans ingenuity.
The most useful video in the history of TH-cam videos
The idea and method for foam cutting is brilliant. Great job.
Cool to see how you did it. Thanks again Jeremy for the Big Mac cut. She's ready to maiden. This summer when I'm down there I'll maiden with y'all.
It will be great to fly with you all again!

Watching him do this is person is even cooler. Nice tutorial J.
What a brilliant idea great video well done that man
Very clean
EXCELLENT tutorial. Thanks mate. Subbed
He speaks so gentle
He touches gentle too
What a great video. Thanks for making it.
well done!
And I was having trouble sleeping, thanks Jeremy
No problem. Best treatment for insomnia on the internet.
Wow that's clever - Thanks
phenomenal
Awesome tutorial Jeremy!!
Thanks man!
impressive that you can actually cut that accurately enough with the wire
Could you do a video of a manually fed cut vs using this pendulum fed? Would be interesting to see the difference, and if the PF is worth adding to the TWC. Thanks.
Good idea. Not sure if we will make that but will consider.
Best part: “... once you get it going and you’re doing a few of these for your buddies, you’ll have it lined up...”
Ha!

Hello,
Please can you indicate the dimensions of the wing (length, tip chord, chord, sweep) and the profile used . Thank you very much. Great job.
Thank you
You're welcome
Awesome!
Great setup... Please share the airfoil template used for both centre and tip..
Check the other comments. I think Jeremy may have put some info in there.
@@lostwing Please share the dimensions of the template
Too cool
Hello,
Would you have any Zagi plans? Or outline shape of Zagi wing? Thanks.

You should definitely try cutting your own. It takes some trial and error to get the cuts to come out properly but the end result is worth it.
Hey, is there any chance to get the airfoil and drawing of that wing?
??
What is the profile number you're using for the root and tip
Liked and subbed.
Thanks!
I'm a little puzzled about what keeps the hotwire flush to the template? Is there some tension in the ceiling line to pull upwards?
I will have Jeremy get back to you.
Good question. The hot wire glides along the top of the airfoil template so gravity keeps it flush. The bow I use uses steel rods so they have some weight to them which helps. I am also sure to have the bow at a relaxed angle, maybe 45 or so degrees, so as it moves across the wing panel the wire stays flush. Around 16:00 shows the general way it moves over the airfoil.

That makes sense. In the video it looked like the wire was cutting to the under side of the template.
I don't remember if you've moved on to CNC yet, but have you tried adding a foam board shim under the leading edge of the block to assist the initial wire entry instead of pencils? It looks like the pulley forces pull backwards and down, so tilting the leading edge up a little bit might help the wire get around that first curve without needing an assist.

Do you think I could build this in a weekend?
Yes, but a long weekend!
Where can I get this airfoil template?
What is the best sweep for a wing?
Do you make Cores for clients?
No. Just a hobby.
Is there a link to the drawing?
What weight is needed? Below table is some water bottles?
We are using a small plastic diet coke bottle about 2/3 full of water.
What's the size of wing?
We have different size wings. The smallest is about 37" and largest is about 52".

I never did have any success using a bow.

Good tips. This was a spontaneous idea. Next time we’ll do it right.
