If nothing ever clamps to it, is it necessary to be perfectly square?
It's so easy & quick to use a rotary saw (with a diamond wheel for carbon) I'm wondering why all the recommendations are to use a saw guide and a tungsten carbide saw blade? Sure, using a rotary saw will never be perfectly straight and perpendicular but it's close after sanding and if the top cap is only ever clamped to a spacer or stem, does it need to be?
Please correct me
