There is compound indexing as worksI stand corrected; the dividing for 359 does require differential indexing; I did not look far enough to the right on the page to see the change gears; MY BAD! "The book" was one of my apprenticeship textbooks; it has the front cover missing now, but the contents are intact, so no excuses, except old age and lack of attention!
You do need to do calculating
I just use a Excel work sheet for calc
This also found in old books
Most B & S charts go to 230 teeth or 250
But in this case he using a rotating table.
Most are 90 tooth worm
Eather calc or use 20 & 30 gears to the B &S charts
