The Toe is quite hard to do, you need some off cuts of wood and place on the back, so when its clamped its like a square block and not at an angle on the back (due to the shape of the toe, its never square or rectangle). Hope that makes sense.I use wooden doorstops and bits of wood.
Thanks. I did wrap up with plastic like Julians video shows and then clamped it tight for more than 24 hrs. Still, it doesn't look that tight. Maybe needs longer/tighter clamping and then fiberglass tape.
