Drilled the rearmost bearer and corner pillar ready for the bolts to attach the steel reinforcement plates.  I first drilled pilot holes in one of the steel plates then used these as a template to through-drill the bearer.  This bearer has a steel insert so it was quite hard work and tough on the drill bits.  Once the bearer had been drilled 1/4″ clear for the fixing bolts, the two plates for this section were aligned then drilled clear for the bolts.
