Foam Wing Core Cutter. How to BEST use a hotwire cutter.

- เผยแพร่เมื่อ 30 พ.ย. 2022
- If you've ever wanted to make a vacuum bagged wing for a #dlg scratch build, then watch how this gravity cutter will help you get a super smooth accurate cut.
Currently using it for a #f3k build, but would work for any #rc aircraft airfoil or any project
needing #hotwire foam cuts.
In principle it's very basic, but you can't argue with the results and you won't have to waste time sanding out imperfections.
I've left a link for you if your interested in the plans and all files for this build.

You're the Bob Ross of foam cutting. Great videos 😀
Very nice video demystifying how a pulley rigged/gravity fed foam wing cutter works. As others have mentioned - Thanks for sharing!
Brilliant!! Your device solves a bunch of issues with foam core cutting.
Great video. Your instruction is easy to follow. Thanks
thank you, and I'm happy you liked it. More to come..
By far the best homemade foam cores i ever see, congratulations!
thanks!
Really enjoyed the vibe in your video. Was well done and the cutting technique is interesting. Subbed and looking forward to more!
Thank you so much
Randomly found this video, but this seems like a really awesome technique and the video is made quite well! Subbed
Thank you. Glad you found the content interesting 👍
Very nice tool and technique. Thank you.
Glad you liked it!
Very nice foam core cutting! I just use my hands for it but your cutting machine is amazing! Bravo! Nice videos from You! Thanks for sharing!
thank you for the kind words. I'm glad you liked it 😎
Very impressive. Keep posting on the rcg thread! (Dan81)
thank you! I'll document the entire build for all to see and keep rcg up to date :)
Map nice! That’s the way to do it!
GREAT DEMO VIDEO!!!... THANKS FOR "SHARING"!!!!!!!!!!!!
very welcome 🙂
Pretty slick. In the early 90's, I wrote the software for a CNC hotwire cutter that a friend used to cut foam wings for pattern fliers. It was bit of a challenge to get it to cut tapered wings.
glad you liked it.
I'm working on making a cnc that will be able to cut a wing half at once, eliminating the joints and providing a smoother transition 👌 😎
you are a genius
great low key presentation thanks
Glad you enjoyed it!
Thanks. Going to apply this method to my foaMWARi RC airplane ❤
great!...let us know how it worked out :)
Wowww, tankyou i've refrence now
Wow impressive
thanks for the kind words
Simple awesome technique
thanks so much
very nice
thx for the kind words
THANK YOU.................. SURWEEEEEEET
best fot wire foam cutter out there, but it takes ages to cut. still really good tho that cut is awesome
thanks for the kind words
Amazing resource! Thank you! Is there a reason you chose to cut the bottom template before the top?
yes. If you cut the top first the core will end up slightly thinner than desired. Thanks for the question.
Love it. Do you have drawings of this

Found this video informative and easy to understand. See you have posted additional videos.
Like, and subscribed. :)
great!...thank you
Thanks for a great video!
What foam is that?
Thanks for watching and the compliment!
I use Owens Corning FOAMULAR CodeBord XPS Rigid Foam, which is available to me locally at
the HomeDepot. It's meant for exterior walls in new home construction.
It's the lightest XPS foam I've found, without going into exotics like Rohacell.
I'm so proud of being a human
me too...the other options are no gouda 😆
You said you had to change the long side string to 79. But it appears to be about at the 81.5 mark in the video @ 6:18. Is that correct?
Hi
I think I had to splice in another clip at that mark if I remember correctly to show unhooking the latch.
Now you just need to make it so if you try to turn it on without releasing the latch it gives you a electrical shock
right
Good job! You deserve a subscripe 😂
thank you!
Shame the Synergy 2 section is not available in clasic x/y coordinents :-(
hmmm, I've never used X/Y. I'm sure you probably know, but here is a link to all the Synergyll files.

Maybe something there could help you.
@@amonus-air2160 I have taken the liberty of converting to X-Y coordinates in a DAT file as well as loading them into a DXF file at unit scale. If you are agreeable and anyone is interested they could PM me and I would send.
thank you John. If anyone inquires I'll let them know 🙂
I really want to build a DLG glider, but now it looks like I have to build a foam cutter first. I can't think of a thing that could go wrong.
edit: The nails are for extra weight, correct?
thanks for the question. Yes, I used what-ever I had to add a little more weight on the arms to force it down more 😎👍
@@amonus-air2160 I have plastic sheaves on my shopping list today, wish me luck!
Any reference you can share on the power supply for the hotwire?
yes, Google hotwire Cutter Power supply diy. There's a guy who goes through it in detail, forget his name.

I used a 12V 15A 180W Power Supply . Bought it from Amazon...www.amazon.ca/gp/product/B07DN7MYD1/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
@@johnnichol9412 yep!...sounds about right. I get more consistent results when you eliminate variables like amperage and feed speed
what is the longest block (span wise) that you can cut with this
Hi!
I've personally done a 55cm span for a 2 airfoil dlg, and I had zero issues. I can only assume that at some point in going extremely wider, wire dragging would be a concern.
Thanks for the question.
@@amonus-air2160 thanks for the answer!
Great work :-) Our Community are looking forward to the full series and following you :-) The Book Group -- DLG / HLG COMMUNITY for Newbies, Starters & Kids
Thank you for the compliment. I feel honoured to be followed by you and your group, and I'll be posting the entire build as time goes on.
sunny skies 😎
