Take care to ensure that the WC is kept vertical and is well stuck down (100g
“inner layer” resin was used). Hold the stringer in place with a weight (a G-
clamp was used here).
5: Leave this to dry (2hr minimum, overnight if possible).
6: When dry, the stringer must be cut (using tin snips) or ground down to the
correct height using an angle grinder. Firstly grind slightly down at one point
along the blade (it is best to start at the blade tip). Place a simple flat edge
(ruler etc) at the grind point. When at the correct height, the ruler should rest
on all three points: both edges and the stringer. If the straight edge does not
lie flat, grind down slightly and test again with the straight edge. Do this until
the straight edge lies flat on all three points. Be careful not to go too far.
Cut a ‘V’ notch into the stringer.
It is at the correct depth when a straight rule
exactly touches all three points, A, B and C
