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

Рет қаралды 29,710

Жыл бұрын

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 😀

Without getting in the mud myself I don't understand what is being solved here, but clearly it's something. I'm sure I'll will be back here after I build a hot wire cutter and screw up some foam.

in a nutshell, the feed table will give you a consistent travel speed which gives you a smooth cut that you can't do by hand.

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 👌 😎

Amazing resource! Thank you! Is there a reason you chose to cut the bottom template before the top?

@amonus-air2160 Жыл бұрын

yes. If you cut the top first the core will end up slightly thinner than desired. Thanks for the question.

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.

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.

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.
