Disassemble the chassis and put the two plates together in the register pins. Scribe out the positions for the great wheel arbors, at 2 1/4" from the bottom and 1 9/16" either side of the centre line. Drill and ream to fit.
Next depth the 96tooth great wheel to the centre wheel pinion on a simple homemade depthing tool. Scribe an arc across the centre line, drill and broach. Then depth the centre wheel to the Scape pinion and scribe that arc which will be 2 1/16" furthur up the plate.
