Cut off three notches from every dowel so that they fit the
capping.

Cover corners with the angle plate.

You may
need to use an extra dowel here.

Fit the
pre-mitred
capping so that the square end is over the middle of a BlocX.

You may need to cut one or both pieces to achieve this. Cut half way between the holes.

Work to the next corner and cut the mitred pieces to suit

Fit full lengths of the capping by starting at one end and hammering them on with a wooden
block.
