EXACTO HELICAL GEARS
With the latest additions to the Exacto family of helical gears, 60 and 48 teeth, available both in right-hand and left-hand versions, greater possibilities have been added to the range. Exacto has been a leader in expanding the original Meccano limited family of helical gears. Now transmission ratios from 1:1 to 1:5 between parallel or perpendicular shafts are possible. Moreover, all the Exacto range of helical gears (12, 24, 36, 48 and 60 teeth) share a most practical property: they all mesh at hole distance or at half-hole distance.
Exacto also provides the traditional 14 and 35 teeth helical gears provided by Meccano , both in right-hand and left-hand versions.
