Step #1: Prepare filesPrevNext
- Download the files and assembly instructions from OpenDesk (opendesk.cc/designers/will-holman), and translate the DXF drawing into toolpaths using your favorite CAM program.
- The toolpath order, as seen in the drawing, should be:
- Green: Drilling toolpath
- Cyan: Pocket toolpath, cut on the vector, 3/16" deep
- Red: Profile toolpath, cut through the material on the outside of the vector. Add at least 3 tabs per piece to hold parts in place.
Step #2: CutPrevNext
Secure the plywood to the spoil board with screws. Note that there’s a 1-1/4" border built into the file for screw clearance. Choose your tooling. I used a 1/4" upcut endmill. Home the x and y axes, then calibrate the z-height. Run the toolpaths.
Step #3: FinishPrevNext
Cut through the tabs with a pull saw. Sand the faces with an orbital sander and ease the edges with a sanding block. Apply finish of your choice — I used butcher block oil and citrus based wax for an Earth-friendly shine.
Step #4: AssemblePrevNext
- Fasten the arms to the side frames by feeding zip ties through the matching holes and pulling tight. Secure the sides to the front and back frames, forming a box.
- Hitch the 3 seat panels together in order of descending size, without tightening the zip ties all the way, to form a flexible “hammock.”
- Attach the seat to the base through the middle of the first and last seat panels. This is a bit tricky; it helps to lay the chair frame on its side so you don’t have to support the weight as you attempt to tighten the zip ties. Then snip off the tails of the zip ties. Add a thin cushion made from closed-cell foam camping pads for extra comfort.
