    I would think the teeth were cut in three operations.

    1. Vertical slide was set over to the required angle for one side, the clapper box tipped away from the cut face, then cut using the down feed. and cross feed in sequence.

    2. Repeat for other side.

    3. centre the vertical slide and clapper box to clean up the bottom.

    Maybe cut a centre slot first?

    Love all the heavy old iron, made to do a bit of work. The place i served the last year of my apprenticeship was formerly a marine engineers, no work at that any longer, so they were getting rid of the big stuff for cnc small stuff.

    I would love to know how long the horizontal shaper gear took to cut?

    Quicker than you'd think but still long enough to be misery!

    Photos on the budikarya-teknik.com website suggest this Indonesian company has a lot of big old-ish machine tools, but presumably these don't include Sunderland planer, which would surely have made the job a lot easier and quicker.
