العفو يالغالي ....
صحيح كلام اخونا الغالي ابوعمار نوعا ما ,, وهذي طريقه لتقويسها ولكن مكلفه والله اعلم :
ممكن تستغني من طريقة الـ Heat Colour وليس الـ Heat Bending وتضعها في ماء حار , والله اعلم ...
وهذي طريقه اخرى اظن انها تنفع ولكن فيها غموض عندي نوعا ما اتفضل :
Bamboo is a renewable resource used around the world as a building material. Many people use bamboo as a medium for craft projects or even fine art. To work with bamboo for a craft project, you'll first need to learn how to bend it. One method is to soak the bamboo and then bend it to shape while it is still waterlogged. It is then placed in a jig or guideline to dry. Once dry, it retains its new shape. Freshly harvested bamboo works best with this method.
1
Make a jig or guideline. Make a lifesize drawing of the shape you want your bamboo to become. Transfer the drawing to a piece of plywood. Hammer nails every inch or so along the outline of the drawing. Hammer a second row of nails parallel to the first row. Separate the two rows of nails by slightly more than the diameter of the bamboo.
2
Soak bamboo for several hours, until it feels pliable.
3
Bend to desired shape. Grasp firmly in both hands and gently bend until bamboo is the shape you desire.
4
Let dry. Place bent bamboo in your jig or guideline to hold its shape until dry. Make sure the bamboo is waterlogged enough before you start to bend it, or it will break.
