Cutting the parts
| The next step is to cut all the parts needed to build the plane. When finished you should obtain a nice puzzle like this: |
|
 
Isn't
it nice? It looks like a kit. The 2 plywood rings shown on the bottom
right of the photo should be made with depron foam instead. It will be
much lighter.

To cut the parts:
Option 1: You have a CNC milling machine.
In this case you can download the dxf parts files and import them directly into your favorite CAM software.
But you have to remember that I organized the files depending on my
machine and my working habits. You may have to reorganize them.
If you have already downloaded the file DHC2_decoupe_cnc.DXF, you don't need to download each file individually.
 
Option 2: You don't have a CNC. How can you live without it? Time to build one! you can have a look at the CNC section of this site to find more information.
But for now get yourself a cutter and some new blades!
Most parts are made of 3 and 6 mm depron foam. Nothing really complex
here. Just be careful to make clear cuts, assembly will be easier.
The few plywood parts will be cut using a jigsaw.
If you want to use the bitmap files (gif) to print your parts, check
that the size is correct when printing them. Full size is achieved wheb
printing at 72 DPI. For a better quality printing you should use the
DXF files.
The size of each panel is there as an indication. It has a margin of 5 mm around the parts.
