1. Prototype three now a bigger fit by 15mm. Much more comfortable. I've modified it so that the bottom plate at the back of the head now swivels up inside the helmet to allow room to put the helmet on, then swivels back down into position behind the head.
2. Resized helmet on the left 15mm larger than the one on the right.
3. Aluminium templates marked ready for cutting.
4. Cutting aluminium templates on the bandsaw.
5. Cutting with the bandsaw, staying 1/2 millimetre to a full millimetre outside the edge line to be filed flat.
6. Chin piece cut out.
7. Stitch drilling the shaped hole out, staying a couple of millimetres inside the edge line to be filed flat.
