Default Foam Wing Cutting Service

I need some recommendations for a CNC foam wing cutting service that will cut a core to my design. I use AutoCad. Thanks, Dan.

I was looking at some RCM plans, a few I considered asked for foam core wings, If companies can do these I would certainly review some of the kits.

On the topic of foam, what type of foam do you use? I've seen others using afoam for cowl plugs etc using a foam which is sorta pale blue in colour. Anyone know whatits called? If there are any other Aussies out there who know the answer to my questions, can you also add places where you can buy it.

Thanks in advance

Adverse, I’m not a foam expert but here’s the little I know. Polystyrene foam is the beaded type of foam that is use to make foam cups, coolers and our foam wing cores. You can pluck the beads out with your finger nail. It is usually white but could be any color. Polystyrene foam is the cellular type. It sands very easy and is the kind that is used for molds. Polyester resin that is used to make the cowls, etc. does not affect it. It is usually colored. Now with that being said, I hope I am not too wrong because lately I have seen a multitude of foam names and types available. Maybe someone out there can pitch in and give you the latest information. You can find them at your local plastics/foam shops in the telephone book. Here’s a thread where a good technique was very well described. Dan.

Interesting Thread.

I need some small tapered wings hot wired and cut.

I'll take help from anyone.

Information or better yet, someone who can do the cutting.

Yes, I expect to pay for this service.

There are lots of videos on Youtube with cheap bows and transformers. It is (or can be) pretty basic unless you want the cnc stuff. I just use a 10 amp battery charger and a 30" 1" x 3" bow with .020" wire, and it works OK, a bit wavy. The pink or blue foam sands out the waves nicely. None or these take polyester resin, the white beaded foam either. Around here there is a brown foam sheathing that takes the resin. I believe the white is EPS expanded polystyrene, the pink and blue is EPU Expanded polyurethane, the brown is polycyanurate or something? Nastier fumes. Then the EPP polypropylene which is nice and flexible for the little foamies. For normal glow planes I like the pink, it is a bit lighter than blue, and sands nice. (I make a lot of mistakes) Anyway, check Youtube, lots of info there, some is good, others are fluff. Practise a bit, and after a while you will get acceptable results.

Airspeed,

Thanks for the reply.

I probably should have mentioned I cut foam wings years ago. I haven't cut a wing in 30 years.

This job is a one-up. Only six small pieces.

So, I'm really looking for someone to cut them.

The information I was looking for was CNC cutting.

One Vendor made it sound like a great deal of work. Set-up he wanted 125.00 even though I sent him a file with all the drawings plus airfoils.

CNC is suppose to make everything quicker?

Yes, I did look at You Tube.

I am pretty sure that he uses a wire with the root and tip airfoils CNC controlled. Templates are not used. Dan
