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!
