Don't worry about it. Wait until you start seeing how the canard lines
up, or the keel lines up, or the nose lines up so that the gear retracts
thru the center of the nose, or the whale tail lines up with the wiring
ducts. The center line of a Velocity isn't even a line, it is a curve.

During construction I noticed this happen also. I carefully line up the
spar, the gear legs, the gear camber, trimmed the ends of the legs, put
on the brakes and wheel, put the plane on jack stands and test the
retract. Eveything fine. A year and a half later, after wing and strake
construction, I test go to test the retract and discover this 3/8"
difference only towards to ground, not the nose. I also had to add 3/8"
to the left canard bushing to get the canard to line up with the wing
