Yes, the volumes were made by myself. Initially I used my track saw which took a bit of time lining everything up for each cut, but I later worked out that with a small enough piece of plywood I could manage with a sliding mitre saw (AKA
Fergus). This was much quicker.
The board wasn't just for me and we're at different abilities (although I hadn't made much improvement for years and the same couldn't be said for my wife!), especially on steeper things, so the board was 'designed' with that in mind.
