I had decided to use epoxy and screws as pins to fix the mitre joints... one of the problems of putting in screws (over dowelling) is it creates a hole where the screw goes in... tada! tapered plug makers!!... obviously you can't just buy a piece of dowel to plug the hole 'cause the figurative pattern would be disrupted ... so you have to match the 'figure' or grain in the wood and create your own tapered plug from very near the hole (and with Silky Oak having so many different patterns each set of holes - four all up - have to be individual sourced)

first select a piece from the immediate cut of below the leg... then jigsaw from that a piece about 7mm wide and match the grain to the screw hole...

... then using a tapered plug cutter cut the plug naking sure you pencil in an arrow for the grain direction...

then carefully massage it into place... and cut it off with a flush cut saw. You'll have to see the finished result!
