The next step was to dry fit everything, unfortunately I didn't take any pics of that until after I primed the parts:
Pic 1: Parts all layed out on cardboard ready to be painted (and of course I still got paint on the floor (nuts), oh well )
Pic 2: Gantry dry fitted
Pic 3: Same setup, different angle
Pic 4: Making sure the table is square when being glued up (the primer paint 'overspray' was removed shortly thereafter).
