  • Hi John!  I didn’t work on this gearbox but I do remember it being built, some pretty impressive gearwheels being used there!

    I seem to remember the whole assembly being turned at a reduced speed to bed the gears in, and, if I’m not mistaken, a small amount of ‘lapping paste’ was used to get a good ‘bedding-in’ of the gear teeth. For anyone not knowing what lapping paste is, it is a gritty and slightly oily substance which was used primarily to lap/bed-in valve seats. In photo 3 you can see the small electric motor that was used to drive the gearbox during testing etc. Oh, and behind that, the tea machine outside the tool stores!

    In photos 1,3 & 4 is Steve Bick and in number 2 is Graham ‘Taffy’ Hall. A great man to work with and an excellent fitter!
