Abstract:
1. A method of shimming a structural surface, comprising: defining a reference plane in a fixed condition relative to the structural surface, said reference plane being spaced apart from said structural surface, a respective distance of said spacing being different at least a first position and a second position along the structural surface; providing a measuring device comprising a reference portion fixable in relation to said reference plane and a measurement portion, said measurement portion being operable, by movement relative to said reference portion, to ascertain a differential distance between said structural surface and a reference position of said reference portion which is coincident with, or has a predetermined spacing from, said reference plane; locating said measurement portion at said first position along the structural surface; fixing said reference portion in a predetermined relation to said reference plane at said first position; operating the measurement portion to take a first differential distance measurement representative of the respective distance of said spacing present between the structural surface and the reference position of the reference portion at the first position to determine a first differential distance; relocating the measurement portion at said second position along the structural surface; fixing said reference portion in said predetermined relation to said reference plane at said second position; operating the measurement portion again to take a second differential distance measurement representative of the respective distance of said spacing present between the structural surface and the reference position of the reference portion at the second position to determine a second differential distance; and preparing a first spacer having a thickness based upon said first differential distance and a second spacer having another thickness different from said first thickness based upon said second differential distance.
