If however, it was necessary to cut six flutes, the indexing would be 80/6 = 13-1/3
turns. 13 complete turns are easily made, however, the 1/3 of a turn involves the
use of the index plate and the sector arms. Remove the handle from the worm
shaft and mount the proper index plate, sector arms, and index crank.
To get 1/3 of a turn, choose any hole circle which is divisible by the denominator 3,
such as 15, then lock 1/3 of 15 = 5 holes on a 15 hole circle. Therefore, the
indexing for seven flutes would be 70/6 = 13-1/3 turns or 13 complete turns plus 5
holes on the 15 hole circle.
EXAMPLE: Calculate the indexing for 9 divisions.
80/9 = 8-8/9 turns = 8 complete turns plus 24 holes on a 27 hole circle.
Divisions 2 to 100 are possible when the additional dividing attachment is used.
Table 1 precalculated provides a quick answer to the problems of index plates
and sector arms settings.
