Name and write brief notes on any THREE methods of veneers used in construction. (i) knife cutting (ii) rotary cutting (iii) saw cut – NABTEB QUESTION

(i) knife cutting
(ii) rotary cutting
(iii) saw cut

(i) Knife cutting: A squared log is fastened to a machine bed. As the bed moves up and down, a sharp knife slices off the veneers’ grain and figure
patterns. They are used as the face veneer.

(ii) Rotary Cutting: A round log is turned in a lathe. While it is turning, a sharp knife peels off the veneer. This passes over a long bench where it is cut up into lengths by a second knife called a guillotine.

(iii) Saw cut: Veneers cut under this method are the stoutest and most costly. They are the most costly because about 50% (percent) of the log disappear in dust. This method is seldom used today because of this reason.
