The next one has gone for a machine cut!
I’ve refined the ‘forty one two’ to now include full single into double concaves in the AKU file.
I’ve also tweaked the rails.
In these screenshots, you can see the comparison to the ‘forty one two’.
Interesting thing I realised is that ‘adding in’ the concaves in AKU actually increased the volume. Which is the total opposite of what you get when you hand shape in the concaves (i.e. you take off foam to make the concaves when doing it by hand). That’s then lead me to realise that the rocker is also different, albeit the rail rocker and not to the centre / stringer rocker …
This then led me to think that when I cut in the concaves by hand on the last one, I have actually flattened the centre / stringer rocker.
Hand shaping vs machine design … bit of a mind twist!
