Hoping to have the first two CNC machines ready to ship later this week. Who wants one? Reasonably priced and I can build custom sizes.

Putting the business prep aside for a bit. Going to visit friends in Newport Oregon the end of March for a week. Perfect opportunity to pull out one of my old projects to put together the prototype for the coast. 96" Pitcheron with a full flying stab added, carbon socked foam fuse, Bling, carbon foam cored wings and stab. Possible "thing that goes up" and split rudder aribrake if time permits.

I've been working on designing a professional grade CNC Foam Cutter for the last couple years. Heres a couple pics of one side of the machine. Unfortunately the rest of my pics died with my HD. I tore down the machine after I was satisfied that it met my expectations. I'm in the process of fine tuning the individual parts and building jigs to be able to to start producing it.

For a few years I've wanted to do a VS Sailplanes VMax scaled down to a 60" wingspan. My wife finally kicked my butt in gear, after listening to me all this time talking about alot and not doing much.

I like to use laminated layers to do my plugs because each layer gives me a guide to sand to. I can finish a plug with almost perfect symmetry and with out the use of templates quite easily and quickly this way.

I used to do my laminations vertically with copies of left to do the right side but you can easily end up with a bend in the plug, so now I do it this way, horizontally. Bend from side to side is less likely, however you now run the chance of puting a bow in the plug longitudinally, but I think that is alot better to deal with than an bent fuse.

1. I modeled it up in Rhino.
2. Placed horizontal planes in 1/8" increments the height of the fuse.
3. Laid in some 1/8" rods for alignment purposes.
4. I then used the intersect tool which gave me the outline of the fuse at each of these heights.
5. Next I took each of these layers and spread them out on 1 plane.
6. Labeled each part. Set this aside, oh and made a copy.
7. Laid out a plane that would be the stock that would be laser cut and made copies of these.
8. Start nesting the outlines from the intersect onto the stock planes ( I had to do staggered cuts to the length of my pieces to accommodate the available stock and cutting area of the laser. Make sure you...Continue Reading
