Wanted to post it into current cnc foam cutter thread, but I think, it is worth separate one. Making a fuse mold from foam slices.



Using this piece of software : http://www.devcad.com/eng/devfusfoam.asp

Tried with 10000 mm long fuselage, and 100 of slices - looks to be working slow, but ok. And you can make even thinner one slices, but cutting from same piece of foam, make sanding close to none,, and with foil on foam plug making - do it in really fast manner.

Totally Awesome Dude!

That method is new to me, and now have me reconsidering the materials I was going to use for my design. Thank you so much for sharing your awesome methods.
You know a hot wire and some blocks of foam a regular homebuilder could cut out some radical fuselages.

You are the KING in my opinion!!!!!!!!!

Please tell the WORLD more about your product.
I gotta say this is gonna open up a lot of design possibility minus the nightmare, complex mold building.
The thing that jumps out at me is how simple it would be to optimize each individual slice.
Hard point installation simplified!
Futher optimize by hotwireing the "slice into inner and outer " cut lighting holes, epoxy back together!
An incredibly light part!!

Did I already say you are the KING?

1. It is not my product. Nor it is new one.. Download ut, and try. It is free to try and ply with it..
2. Yes, it did export to g code/step + simulation.

I think a KR Super 2 would be a better choice
A Mazda ( Twin Rotor) Rotary Powered KR Super 2!
That's the ticket

The pic I posted was my personal project. Basically slimming up the kr2 for more of a fat man's single place (30" wide), with the standard 14' longerons stretch that's usually being done now.

Used symmetry's turtle deck and lower fuselage curve. And the new AS504* airfoils

KrSuper2 has been dead for a few years now. Unfortunately the plans never had a lot of the issues of their design resolved.

However, a full composite KR2 is likely in my future, just pushes my math skills. And CAD skills if you notice how bad the ballpark of the longez canopy fits the fuselage :confused:

Dead?
The killer for the 2 was the core foam choice.
In my opinion, the OP has introduced the super2 resurrection.
This method could put the 2 in a whole new light.

September 2014 was the last update of the super2. So 5 years later yes dead.

Cnc hotwired foam makes a lot of sense. Big "dock foam" EPS blocks are cheaply bought local, and can be hotwired...
