Hi Klaus,

as smooth as possible is an "unclear" target In your opinion, how smooth should a homebuilder aim for? The combination of surface roughness and a true section is a challenge if working by eye and hand accuracy.
Is there a crossover point between the importance of sectional trueness and surface smoothness?

A CNC millcan work down to 0.001mm accuracy and some light sanding will give smoothness (or the machine can produce that as well if it is good enough).
