All  |   Discussion (0)Bending wood

There are several methods to bend wood: (i) using heat, (ii) laminating, (iii) cutting notches, (iv) chemicals.

(i) Heat: Dry heat may burn timber; to avoid this, use a steaming box, or more cheaply, wrap wetted timber in black plastic and leave in the sun for several hours. The timber will bend far more easily.
(ii) Laminating: Bend thin timber strips then glue in layers for strength.
(iii) Cutting notches: Cut parallel grooves 10-15mm apart to two-thirds the depth of timber. After bending, glue veneer over the bend to strengthen the bend.
(iv) Chemicals: Chemically pure anhydrous ammonia is used in commercial applications to bend timber, but is very dangerous and can weaken timber.   kellyjones00 (593)
