The earlier spiked type has the worm machined, hardened, ground etc and is then spiked onto the shaft with the thrust washer. Then the spikes are machined flush. I always check the spikes are not cracked when rebuilding a box by tapping with a small chisel and hammer.
If they are cracked or missing, the repair that I have done is to chop the shaft higher up and machine a new end with new spikes, silver solder together, replace worm and spike it over as described above.
Hope this is of help.
