SAWING OF TIMBER

Sawing of timber is a timber that is cut from logs into different shapes and sizes. Sawing of timber is generally cut into varying rectangular widths and lengths, but may also be wedge-shaped. Common  Sawing of timber products include solid timber beams and more rectangular timber sections.

  • The process of giving the required shape and size to the timber section is termed as conversion sawing of timber.
  • By sawing, timber can be converted into transferable parts.
  • Various methods of Sawing of timber are…

i. ORDINARY/ FLAT/ SLAB SAWING:-

  • parallel cuts made throughout the length of the log i.e. tangential to the annual rings.
  • Easiest and economical method.
  • Causing twisting and warping of planks.

ii. QUARTER SAWING:-

  • When applied to wood not having distinct medullary rays, this method produces very fine wood.
  • In this method saw cuts are made at right angles to each other.
  • The tendency to cup i.e. to curve in a transverse direction.

iii. TANGENTIAL SAWING:-

  • In this saw, cuts are made tangential to annual rings that meet each other at right angles.
  • It is suitable for those sections which have distinct annual rings and indistinct medullary rays.
  • Not suitable for flooring.
  • The section observed to have the least strength.

iv. RADIAL/ RIFT SAWING OF TIMBER:-

  • Saw cuts are in a radial direction parallel to medullary rays in this method.
  • Wastage of timber is observed to have maximum in this method.
  • Section obtained is having maximum strength and induces decorative effect too.

मैं रावन, लंका का राजा, मैं वह रावण हूं जिसने अपने सीस रूपी पुष्प चढ़ा चढ़ा कर उमापति महादेव की पूजा की है। जब मेरा हाथ खड़क की ओर जाता है तो आसमान में लोकपाल भय से कांपते हैं। जिन भुजाओं ने स्वयं कैलाश को उठा दिया था उस भुजाओं के फड़कने मात्र से देवता गांधार और नक्षत्र भी भय से सांस लोग लेते हैं।
