In this DIY tutorial I'll show you how to make a bamboo bed with very basic hand tools and without the use of any metal nails or screws.
Cut two bamboo canes of 220 cm length (the tip of the cane should include a node). Continue by drilling two double holes in each bamboo bed frame rail (A). The first hole should be made at 8 cm from the tip of the bamboo cane and the second hole at 202 cm from the first. The holes should be 7 cm in diameter.
Rotate the bamboo canes (A) 90° and drill 4 single holes (not penetrating the two sides of the cane). Drill the first hole at 24 cm from the tip of the cane (the one with the node), and the other ones 56 cm from the first. All holes must be 7 cm in diameter.
The first cut is made with an angle of 45° starting at the end of the cane (B1). This cut must be made at both ends of the bamboo.
The second cut is also made at 45° using the previous cut as a reference point.
Finally, the inner edges of the fish mouth joint must be sanded or carved out, and the tips must be rounded. This is to create a better fit at the time of assembling the bamboo bed frame. This video demonstrates another technique to make bamboo fish mouth joints.
Drill a 7 cm diameter single hole in the center of the longest side of the bamboo cane (B1).
Drill two double holes at both ends of the bamboo cane (B2). These double holes should be drilled at 8.5 cm from the ends of the cane and have 7 cm in diameter.
Drill 3 single holes in the (B2) cane. The first and the last hole at 30.5 cm from the end of the bamboo cane, and one in the center which should be at a 22 cm distance from the others.
Place the 4 bamboo crossbars (D) in the holes that were previously made in the bed frame rails (A).
