Hello,

Looking for someone who has a cnc router table to do some cutting of Depron foam... any ideas?


thanks

If its 2d cutting, try your local signmaking shop. Most of them are set up for this pretty good. I had these aluminum honeycombing jigs made from autocad files a few years back & the price wasnt too made (considering the Armstrong Alternative). If its 3d profiling, most likely a different ($$) outfit altogether.

Scott,
Let me know what it is and I may be able to CNC it on my mill 2D or 3D. I have played around some cutting a foam plug to make an engine cowl, and I'm getting ready to make some floats out of foam and then glass them. You can e-mail me or post it here.

ptxman,

Your wing looks great. How do you get your bow through each of those holes? (assuming that its hot wired)

I made a pilot hole in the middle of each cell with a rod in a soldering iron. It is hot wirred but not with a bow. I dont have a pic handy but its just 2 wood handles which have the power wires running to a metal screw hook in the ends of the handle. The hot wire stays on one hook but the other is kind of a question mark shape (?) so the hotwire can slip on & off but still hold tension. When the handles are connected it starts to heat up (the circuit is "on"), or you can rig up a foot pedal switch. I clamp the jig & foam assembly perpendicular so it is easier to steer the hotwire around the cell. Its very easy once youve done a few, just very boring work.

Cool. Is that a white foam wing that gets sheeted, or a epp type wing?

Regular white polystyrene virgin bead 1 pcf (lb/ft3) foam.

PATTERNPILOT-
If you are looking to do a lot of CNC work you may want to set up your own machine. Check out the following that I came across. I can't vouch for anything, just simply remember seeing it once.

They may have something you like, or not. Worth a look anyway.
