Thread sizes and machinery
I spent 13 years turning wrenches in the boiler rooms and engine rooms of warships in the Canadian Navy.....consider this conundrum....the Gear Boxes were Swedish, the control system was Brit/Can, the engines USA Pratt and Whitney....the HP air compressors were Brit, the LP compressors were US the Diesels were German and so on and so on....
we carried British Standard Whitworth, SAE and Metic of all sorts up to the big buggers for the main shaft bolts....3+ 4 Inches /Cms across. Not to mention Fine, Coarse, double start acme and triple start Acme threads.....Sheeesh I forgot to mention all
de tum renches to bye.
cheers
Mike
