Australiaâs tallest trees can be found in the south-west of Western Australia in the Valley of the Giants. Giant tuart, karri, and rich red jarrah which live for up to 500 years can be found here.
Feeler gauge set. A feeler gauge is a tool used to measure gap widths. Feeler gauges are mostly used in engineering to measure the clearance between two parts. They consist of a number of small lengths of steel of different thicknesses with measurements marked on each piece.
With feeler gauges 25, etc., in the gap 51, it is obvious that the pipe can be drawn up tightly against the gauges. Thereafter the heavy strong-back clamp elements 31, 31a, etc., can be tightly engaged at both ends tohold the pipe elements against further relative movement.
