As near as damn it, depending on tolerance, although in many shipyards on the Lagan tolerance wasn't tolerated. Neither was abstinence
Slow chaps like myself assumed there was about 40 thou in 1 millimetre and then multiplied or divided as necessary. In A-Level maths this is called calculus or matrices or something complex. Ah the good old days. A white boiler suit with a wee notebook in the breast pocket sodden from sweat, engineroom boots without socks or laces, an 8 inch (50,000 mm) Bacho shifter and a yellow or orange USA safety torch which never worked and 4 hours of bliss.
