You can take the Flexbow anywhere easily by its efficient way of flat packing. It can be made from sheet steel / carbon / spring steel and fiber glass. let's get started.
Step 1: Materials
For this project, you will need:
1. Sheet steel 2 m long, 3 cm wide, 0.5 cm thick.
2. Lock bolt with nut galvanized Diameter M5, 20 mm long, total 8x
3. 8x hexagon nut plastic ring
Step 2: Technical Drawing
On the technical drawing you can see an exploded view where you can see how the bolts and pieces exactly come together.
The nuts and bolts are rotated each time facing each other so that it can absorb more torque with the bow and therefore better bind together .
Step 3: Size Sawing Pieces
There should be cut:
5 pieces having a length of 35 cm
1 piece having a length of 24.5 cm
Step 4: Sheet Metal Laser Cutting/ Metal Drilling
In step you 4 have the possibility to choose for laser cutting all the pieces or to drill all the pieces himself with a metal drill and then filing off the wide slots to the desired size.
When the pieces of board make sure you sign off the documents in advance. This works well with a utility knife. Then mark where you have to get the holes with a sharp point and hammer.
All holes must be drilled with a diameter of 5mm and 6mm galvanized because the lock bolt with a nut must be galvanized with a fit of 6mm .
Step 5: Assemble Pieces
In building the arch you should consider how the bolts come into the holes.
On the pictures you can see how they have to fit exactly.
All dimensions can be found on the previously mentioned technical drawing.
Step 6: Chucking
In order to fold the bow you can push the two ends , where the string comes around in the middle of the arc between the two plates.
Because the ends are rounded, the process goes smoothly and there should be no spacers between the arch.
Step 7: Flat Packing Instructions
Here you see the system how you can fold the bow for easy to carry / transport
Step 8: Presentation Video
In the clip is you see how you can tension the bow efficiently from the flat pack form.
