Lots of mortices. 2 each for the 8 legs/stiles and 1 each for the 4 top and bottom rails of the sides. 20 altogether. These are deeper than my router would go, so I drilled out as much as I could with the pillar drill and then used a chisel to clear out the rest. Harder work than just using the router for everything, that's for sure! Gives me new respect for the time and effort it would take to do everything by hand, like they did in the olden days!
