Hi! I work in school's Design and Technology department and presently trying to sort out which parts fit with which particular machine. We have two Harrison lathes, one is a Harrison 9" L5 type and the other is a Harrison 140 which has an 11" swing and is a gapbed lathe, also an L5 type. I need to find out which of the loose gears match which machine, so that they can be stored with the relevant machine as neither machine is kept in the same room.
Below shows the gears with their number of teeth which are currently fitted to the machines and a list of the loose gears I have. Where there is a number in brackets following the quantity of teeth, this indicates how many gears there are of that size and teeth number.
Harrison 9" - fitted gears: 20/80/100 Harrison 140 - fitted gears: 25/100/80
Loose gears for Harrison lathes : 40(x2) / 50(x2) / 60(x3) / 63 / 65 /70 / 80 / 120 / 127
Any help would be greatly appreciated!
